Full textAbstract:
The scent of scented cyclamen flowers weakens when the plants are displayed for long periods, and this phenomenon is affected by the environment in which the plants are displayed. Counteracting environmental effects on scent intensity requires an understanding of floral scent emission during display. Here, we used gas chromatography-mass spectrometry and sensory analysis to evaluate the influence of light intensity on floral scent emission from scented cyclamens kept indoors and in a greenhouse. For the greenhouse cyclamen, odour intensity was nearly constant throughout the study period. In contrast, the odour intensity of the indoor plants had decreased by 13 days after flowering, and the odour intensities of the indoor and greenhouse cyclamen differed significantly. Rank correlation analysis showed a positive correlation between odour intensity as determined by sensory analysis and the total amount of volatile compounds released as determined by gas chromatography-mass spectrometry. That is, the sensory analysis results could be explained in terms of the emission amounts of odour compounds.

Agriculture is a vital sector for a nation's livelihood. However, in the near future, the agricultural sector faces various challenges, particularly related to environmental and cultural issues. In this era of digital transformation, technology plays a crucial role in the agricultural field. Research is conducted to control the quality of nutrition and water intake for hydroponic plants to ensure their healthy and high-quality growth. The controlled parameters for nutrition include pH and nutrient solution availability, while water intake involves temperature, acidity (pH), electrical conductivity, and nutrient dosage. These parameters are detected by pH sensors, temperature sensors, EC (electric conductivity) sensors, and controlled by microcontrollers. The sensor detection results control the pump operation, ensuring a continuous and quality water intake rate. The growth of Brazilian spinach plants under study is observed with water pH controlled at 6.5 – 7 and nutrient electrical conductivity at 2 – 2.1 ms/cm. Test results demonstrate that the growth of plants in the research growth medium and the comparison growth medium significantly improves, even though the growth is not uniform across all plants. Plants in the research growth medium exhibit significantly better growth compared to those in the comparison growth medium.

"Is there potential for hops production in an indoor system using LED lighting?" OBSERVATÓRIO DE LA ECONOMÍA LATINOAMERICANA 22, no. 7 (July 9, 2024): e5740. http://dx.doi.org/10.55905/oelv22n7-124.
Full textAbstract:
Hops production largely depends on daylength shortening for proper flowering. Innovative systems like indoor cultivation with LED lighting allow a precise control of photoperiod regardless of season. However, such systems are still under development for most crops and there isn’t a solid framework on which indoor hops cultivation can be referred to. The aim of this study is to provide a descriptive report on how hops plants can develop and flower in an indoor system. A growth chamber was designed to accommodate hops plants, providing lighting and two training methods: parallel and spiral. Within 90 days of vegetative growth the plants had substantially developed and photoperiod was reduced from 16 to 10 h. Flowering began 6 days after photoperiod shortening. Spiral training can provide a more ergonomic usage of vertical space, allowing hops plants to better develop length-wise. Although structural adjustments and further research are still needed, there is potential for hops production in an indoor system using LED lighting.

Orchids are epiphytic plants with high popularity. Orchid is a plant that can process its own nutrients with the help of other media. Parameters that need to be monitored include air temperature, air humidity, and soil moisture. These parameters greatly affect plant growth. Plants can grow well if humidity, temperature, and light intensity are met properly. Good orchid humidity ranges from 50 – 80%. Humidity should not be too high at night and not too low during the day. In addition to humidity, the temperature where you plant orchids must also be maintained. The ideal temperature for orchids is daytime temperatures between 27-30 degrees Celsius and night temperatures between 21-24 degrees Celsius. Based on these problems, a Design and Development Tool for Monitoring Soil Temperature and Moisture on the Growth of Indoor Orchid Plants is Based on WeMos with Indoor Energy. In this design, the results of sensor readings will be displayed in the form of data which will be accessed via the web server on WeMos. To read the temperature, air humidity, and soil moisture, several sensors are used, namely: DHT 22, soil moisture sensor, and a relay connected to a mini water pump using an indoor cultivation method where the energy source uses UV waves by LED light. From the results of the implementation and testing, the growth period will be obtained more faster than the normal cultivation. hopefully, this research will help people who care for orchid plants to be able to monitor their orchid plants efficiently in indoor conditions so that these orchid plants can always be in the best conditions of temperature, light, and soil moisture.

Full textAbstract:
Vertical farming is a novel type of food production in indoor environments with artificial lighting and controlled cultivation conditions. In this context, sustainability in small-scale indoor cultivation systems is crucial. Sustainability can be achieved by optimizing all the cultivation factors involved in the production process. The effects of different photoperiod conditions under different timing during plant development—from sowing to germination and maturity—have been studied in a small-scale indoor cultivation area. The main objective of this research was to investigate the possibilities of an optimized photoperiod for basil plants to reduce the energy demand cost of the cultivation unit. Three different photoperiod treatments (P8D16L, P10D14L, and P11D13L) were applied to basil plants with stable light intensity. Furthermore, the photoperiod was shortened to test the reaction of the biomass from the plants in a reduced energy demand system. The dry biomass produced was measured along with the energy consumed in each treatment. The basil quality was assessed by measuring different physiological indices, such as chlorophyll a (Chl a), chlorophyll b (Chl b), total chlorophyll (Chl tot), the fraction of photosynthetically active irradiance absorbed by the leaf, and leaf temperature. The results of the study showed that a shorter photoperiod did not negatively affect the quantity and quality of the basil plants. Continuously, the evaluation of the energy demand variation under the different photoperiod treatments can provide a significant positive impact on the energetic, ecological, and economic aspects of small-scale food production.

Full textAbstract:
With intensification of urbanization throughout the world, food security is being threatened by the population surge, frequent occurrence of extreme climate events, limited area of available cultivated land, insufficient utilization of urban space, and other factors. Determining the means by which high-yielding and high-quality crops can be produced in a limited space is an urgent priority for plant scientists. Dense planting, vertical production, and indoor cultivation are effective ways to make full use of space and improve the crop yield. The results of physiological and molecular analyses of the model plant species Arabidopsis thaliana have shown that the plant response to shade is the key to regulating the plant response to changes in light intensity and quality by integrating light and auxin signals. In this study, we have summarized the major molecular mechanisms of shade avoidance and shade tolerance in plants. In addition, the biotechnological strategies of enhancing plant shade tolerance are discussed. More importantly, cultivating crop varieties with strong shade tolerance could provide effective strategies for dense planting, vertical production, and indoor cultivation in urban agriculture in the future.

Full textAbstract:
Interest in cultivating cannabis for medical and recreational purposes is increasing due to a dramatic shift in cannabis legislation worldwide. Therefore, a comprehensive understanding of the composition of secondary metabolites, cannabinoids, and terpenes grown in different environmental conditions is of primary importance for the medical and recreational use of cannabis. We compared the terpene and cannabinoid profiles using gas/liquid chromatography and mass spectrometry for commercial cannabis from genetically identical plants grown indoors using artificial light and artificially grown media or outdoors grown in living soil and natural sunlight. By analyzing the cannabinoids, we found significant variations in the metabolomic profile of cannabis for the different environments. Overall, for both cultivars, there were significantly greater oxidized and degraded cannabinoids in the indoor-grown samples. Moreover, the outdoor-grown samples had significantly more unusual cannabinoids, such as C4- and C6-THCA. There were also significant differences in the terpene profiles between indoor- and outdoor-grown cannabis. The outdoor samples had a greater preponderance of sesquiterpenes including β-caryophyllene, α-humulene, α-bergamotene, α-guaiene, and germacrene B relative to the indoor samples.

Full textAbstract:
Greenhouse cultivation has no seasonal limitations and research is being conducted globally to assess control of environmental factors within greenhouses to optimize growing conditions. Attempts to improve the environmental factors in greenhouse cultivation include control of temperature, relative humidity, light intensity, carbon dioxide level, and air flow rate. Furthermore, indoor cultivation systems (growth chambers) have been developed and researched for comparison with greenhouse cultivation. In our study, comparative environmental data were collected in association with cannabis cultivation for a greenhouse and growth chamber, since commercial cannabis cultivation can include such methods. Accordingly, the data in this research were collected by choosing the same cannabis cultivars for both cultivation methods and by controlling the internal growing environments that affected cultivation. Data also were collected on the plant biochemical properties over the same time period and the collected data were analyzed using psychrometric charts. The findings of this research show that if the internal environment of the indoor cultivation method is well-regulated, better results in cannabidiol (CBD) extraction from blossoms can be achieved as compared to greenhouse cultivation, in which environmental regulation is less precise. Therefore, we conclude that if we can control the internal environment of greenhouse cultivation to be similar to the indoor cultivation method, the productivity of the two methods should be similar. The findings of this research can be used to develop greenhouse cultivation methods for other plants in order to improve future productivity and efficiency.

Full textAbstract:
Bacopa monnieri, a cognitive-enhancing herb crucial in health supplements, faces quality variations and contamination by toxic substances in conventional field cultivation, which hinders industrial use. Here, indoor cultivation of diploid (2x) and tetraploid (4x) B. monnieri using hydroponic and soil systems was studied. Soil cultivation promoted longer shoot lengths but resulted in lower biomass and chlorophyll contents compared to hydroponic cultivation. Conversely, soil cultivation significantly elevated total phenolics, total triterpenoids, bacoside A3, and bacopaside X contents in both lines, showing 1.7- to 3.3-fold increases over hydroponic cultivation. Furthermore, 4x plants grown in soil had higher bacopaside II and total bacoside contents than hydroponically grown plants, with 2- and 1.5-fold increases, respectively. Yet, no significant differences were observed in growth and pigment between 2x and 4x lines under the same system. Similarly, no significant differences in bioactive compound productions were found between 2x and 4x hydroponically grown plants. However, in soil, 4x plants exhibited higher total phenolic content, bacopaside II, and total bacoside contents compared to 2x plants. Interestingly, 2x plants grown in soil were the top performers for bacoside production per plant. These findings optimize cultivation practices to meet industry demands, warranting further research into large-scale production techniques.

Full textAbstract:
The use of cannabis for medicinal purposes dates back well before the era of modern medicine, but in recent years research into the use of medical cannabis in the medical and pharmaceutical sciences has grown significantly. In European countries, most cannabis plants have been and still are grown for industrial purposes. For this reason, hemp cultivation technology is relatively well researched, while little is known about the key factors affecting cannabis cultivation for medical purposes. The active substances of cannabis plant targeted by this review are called phytocannabinoids. The biosynthesis of phytocannabinoids is relatively well understood, but the specific environmental factors that influence the type and number of phytocannabinoids have been much less studied. Indoor or greenhouse cultivation, which uses automated lighting, ventilation, irrigation systems and complex plant nutrition has become much more sophisticated and appears to be the most effective method for producing medical cannabis. There are many different cultivation systems for cannabis plants, but one of the essential elements of the process is an optimal plant nutrition and selection of fertilisers to achieve it. This review summarises the existing knowledge about phytocannabinoid biosynthesis and the conditions suitable for growing plants as sources of medical cannabis. This review also attempts to delineate how nutrient type and bioavailability influences the synthesis and accumulation of specific phytocannabinoids based on contemporary knowledge of the topic.

Saving energy along with reducing carbon emission is an unavoidable new trend in response to continual global warming. In Taiwan, the energy consumed by commercial buildings and residential houses accounts for about 18% of the total energy consumption with 31% consumed for HVAC (heating, ventilation, and air conditioning) to emit 21 millions of carbon dioxide annually. Hence, in this research, an integrated energy-saving system combining green architecture, recirculation and reuse of water resources, indoor plants to purify indoor air quality, and solar energy and hydrogen energy is proposed for providing HVAC and illumination. The research has accomplished the following: (1) roof-top plants will lower the indoor temperature during summer; (2) utilizing aquatic plants to purify the wastewater for recirculation and reuse will effectively remove BOD and COD from contaminated water; (3) indoor plants are effective in lowering loadings to air conditioners and energy consumption; (4) the solar air conditioner has excellent overall energy saving features; (5) the solar hydrogen generating system and reformed methanol system have been developed applied to develop a 100 W PEMFC (proton exchange membrane fuel cell); and (6) a portable plant cultivation system has been developed to enhance plant growth for removing indoor carbon dioxide so that the building needs not be ventilated much to maintain adequate indoor air quality.

Tomato plants are sensitive toward climate changes thus affecting growth development and pollination of the plant. This study was conducted to assess energy performance and environment in greenhouse agriculture to support tomatoes cultivation using Computational Fluid Dynamics (CFD) and OpenStudio EnergyPlus software. To achieve efficient energy performance and to balance it with the environment in tomato greenhouse, architectural and engineering design have been integrated in the study. Analyses on indoor environment and energy consumption of the greenhouse are carried out by installing various electrical equipment such as exhaust fans and humidifier in the greenhouse to meet indoor environment requirement of good tomato cultivation. Three properties of the greenhouse were monitored and these are temperature, relative humidity and energy consumption. Results show that the proposed greenhouse model in this study could meet the required temperature and relative humidity for good tomatoes cultivation.

Full textAbstract:
The development of various types of plant factories is central to improving agriculture. In one form, it is expanding from the existing commercial plant factories to home cultivation systems or cultivators. The plant cultivation system grafted into the living space for people produces differences in the growth of the plant depending on the lifestyle (cooling and heating, residence time, number of residents, etc.) of the resident. In this study, identical home cultivation systems that automatically adjust environmental conditions (temperature, photoperiod, light, and nutrient solution supply) other than the carbon dioxide level were set in an office and warehouse. The study confirmed how plant growth can differ depending on the amount of carbon dioxide generated by humans occupying the space. In addition, it was confirmed whether the growth of plants can be further promoted depending on the external air exchange speed by a ventilation fan even if the indoor carbon dioxide concentration is the same. Due to the nature of the cultivation system that controls the temperature, the type and speed of the fan were set to minimize heat loss in the cultivator. The airspeed from ventilation fans attached to the indoor cultivation systems of an office and warehouse was adjusted to one of three levels (0.7, 1.0, or 1.3 m·s−1). In this study with two species, Ssamchoo and Romaine, it was confirmed that the office space was significantly advantageous for the growth of Ssamchoo, especially in terms of the fresh weight, root activity, and chlorophyll content. Romaine also had a significantly higher fresh weight when grown in the office. Shoot length, leaf length, and leaf width were longer, and there were more leaves. When comparing the relative yield based on an airspeed of 1.0 m·s−1, the yield increased up to 156.9% more in the office than in the warehouse. The fan airspeed had an important influence on Ssamchoo. The higher the fan airspeed, the greater the yield, root activity, and chlorophyll. However, fan airspeed had no consistent effect on the growth tendencies of Romaine. In conclusion, carbon dioxide produced by humans occupying the space is a significant source of carbon dioxide for plants grown in the home cultivation system, although both the speed of the ventilation fan that can promote growth without heat loss and delayed growth caused by the photorespiration in a carbon dioxide-limited situation require additional experiments.

Full textAbstract:
This review paper highlights about the emission of volatile organic compounds (VOCs) of Cannabis plants. Volatile organic compounds (VOCs) are a large group of chemicals harmful to human health that are readily released into the atmosphere and participate in atmospheric photochemical reactions. Floral Volatile organic compounds (VOCs) are often involved in defence and pollinator attraction. Cannabis cultivation and consumption may lead to additional environmental impacts. Studies found out that Cannabis plants emit a significant amount of biogenic volatile organic compounds (BVOCs) which could cause indoor air quality issues. Indoor Cannabis cultivation is energy-consuming, mainly due to heating, ventilation, air conditioning, and lighting. Energy consumption leads to greenhouse gas emissions. Common compounds to all the tested hemp cultivars include β-myrcene, ϒ-caryophyllene, α-pinene, β-pinene and limonene, reflecting species specificity in the emission of these compounds. β-Myrcene was the most abundant compound in most of the outside hemp cultivars. The terpenes had an earthy musky, and fruity smell may contribute to the odour in Cannabis samples at the vegetative stage, flowering stage, and drying/curing stage. All hemp cultivars are the prolific emitters of terpenoids. The oxidation of highly reactive Biogenic Volatile organic compounds (BVOCs) from Cannabis plants can lead to the formation of ozone and secondary Volatile organic compounds (VOCs) (e.g., formaldehyde and acrolein). In hemp production, considerable odorous emissions occur during field retting. However, more research is needed to address how outdoor air quality is influenced by Cannabis cultivation facilities (CCFs) emissions.

Lettuce or in Indonesia better known as bokor lettuce is a commodity that has bright prospects for cultivation. Green Curly Lettuce is harvested at the age of 25 - 35 days. The price of Green Curly Lettuce on the market can reach Rp. 10,000 to Rp. 15,000 per kg. One of the hydroponic methods that can be carried out for cultivating Green Curly Lettuce plants indoors is a hydroponic system with fog or commonly called Fogponic. Fogponic is a hydroponic system developed from the Aeroponic method, using an ultrasonic fogger or atomizer to atomize nutrients to plant roots. The aims of this research are 1). Designing a water temperature control system device, solution concentration and light height of Fogponic nutrient water in Indoor Agriculture. 2). Create an Automatic Ultrasonic Fogger to maximize nutrition to the roots of Green Curly Lettuce plants. 3), Evaluate the performance of the Automatic Ultrasonic Fogger system by integrating it with the Internet of Things (IoT) via the Thingspeak website. Fogponic design using Ultrasonic Fogger can maximize the little water needed by plants. Even though the use of LED Grow Light cannot replace sunlight in Greenhouses. Automatic Ultrasonic Fogger works according to schedule at 06.00, 08.00, 10.00, 12.00, 14.00, 16.00 and 18.00. Besides that, it will work when the fogging machine detects the water level is decreasing so that it gives a notification to add nutrient water. The Fogponics work system can revive green curly lettuce plants and is better than Deep Water Culture (DWC) Hydroponics. However, it is not significantly different from Bubbleponik and still inferior to simple Aeroponics.

Saccharina sculpera is highly valued for human consumption and value-added products. However, natural resources of this kelp have decreased sharply and it is in danger of extinction. Resources recovery through cultivation is being trialed to enable the sustainable use of this species. In this study, the temperature range for survival and optimal growth of juvenile S. sculpera was identified and applied to field cultivation. This study investigated the survival and growth of juvenile S. sculpera under six temperatures (i.e., 5, 10, 15, 16, 18, and 20°C) and two light intensities (i.e., 20 and 40 μmol photons m-2 s-1) in an indoor culture experiment. In these experiments, the blade length decreased at 16°C under the both light intensities. The thalli died at 20°C and 20 μmol photons m-2 s-1, and at 18‒20°C and 40 μmol photons m-2 s-1. During the field cultivation, early growth of S. sculpera was highest at the 5 m depth and growth decreased as the water depth increased. When the initial rearing depth was maintained without adjustment throughout the cultivation period (from December to October), all the cultivated S. sculpera plants died during August and September. However, S. sculpera plants lowered from 5 to 15 m and grew to 90.8 ± 13.1 cm in July. The seawater temperature at 15 m depth was similar to the upper level of thermal tolerance demonstrated by juvenile S. sculpera in the indoor culture experiments (16°C or lower). The plants were subsequently lowered to 25 m depth in August, which eventually led to their maturation in October. The present study confirmed that improved growth rates and a delay in biomass loss can be achieved by adjusting the depth at which the seaweeds are grown during the cultivation period. These results will contribute to the establishment of sustainable cultivation systems for S. sculpera.

Objectives : In this study, the absorption of heavy metals in the soil from smoking areas using indoor plants and electrical grounding was investigated to increase the utility of indoor plants for soil decontamination.Methods : Soil from plant pots in a smoking area was collected for the experimental plant pot preparations. Some of the prepared pots were connected to electrical ground via an electrode. Kidney beans (<i>Phaseolus vulgaris</i>) were seeded, and their growth were observed. After 30 days of the cultivation, TOC (Total Organic Carbon), and metagenomics profiles in the soil was analyzed. To estimate the behavior of the heavy metals in soil and plants, Cadmium concentrations in the samples were analyzed using ICP-MS (Inductively Coupled Plasma-Mass Spectrometry).Results and Discussion : The connection of the electrical ground to the plant pot induced the rapid growth of plant (48.2 ± 2.3% increase in stem growth), compare to the plant in the pot without the electrical ground. TOC analysis showed that the soil from the grounded pots showed the highest value, compared to the control soil (3.08 ± 1.22%), and the soil from the pot without ground connection (2.3 ± 0.1%). The ICP-MS analysis indicated that the plant body in the grounded pot had the highest cadmium concentration at 0.33 ± 0.018 μg/kg. Using the metagenomic analysis, biomineralization related bacterial species (<i>Nocardioides</i> sp., <i>Streptomyces</i> sp., <i>Sphingomonas</i> sp. etc.) were identified from the grounded soil sample. These results suggested that the indoor plant cultivation with the electrical ground connection as an electrical fertilizer enhances the cadmium absorption by plant, exudate secretion from the plant root, and bacterial flora change in the rhizosphere.Conclusion Cadmium in the soil from the smoking area was absorbed by indoor plant with the electrical ground. Therefore, the application of the electrical ground connection (earth) to the electrically insulated outdoor plant pots might enhance the plant growth rate and physiological activity. This application could be a novel soil decontamination method using plants.

The objective of this study was to evaluate the potential of reusing domestic rinse water in an indoor hydroponic system and compare the growth pattern of Coleus plants using tap water and rinse water. A preliminary survey evaluatedthe knowledge about, home gardening, hydroponics, water usage and utility of rinse water in urban households. The experimental setup consisted of water culture hydroponic system with peat moss media. Data were collected and analyzed from 4 sample groups: Group A (tap water), B (tap water with NPK fertilizer), C (rinse water) and D (rinse water with NPK fertilizer) in a randomized experimental design (N=20) with five replicates.The study was conducted indoors in an urban household under controlled temperature (78ºF), light and humidity (60-70%). Parameters analyzed for assessment of plants growth included height (in millimeters), number of new leaves and leaf surface area. Environmental parameters including, pH and TDS (Total Dissolved Solids in parts per million) of the hydroponic solution, and pH and moisture of soil were also recorded. Descriptive statistical analysis and independent comparisons were done with a 95% assumed significance level (p<0.05).During the 20th, 25th and 30th day, plant height in Group A was significantly (p<0.05) higher than that of Group B and plant height in Group C was significantly higher than in Groups B and D.In terms of the environmental parameters, while rinse water had an alkaline pH, the addition of NPK fertilizer (Groups B and D) resulted in significantly lower pH.Based on the present study results, domestic rinse water can be reused as a successful alternative for tap water in indoor hydroponic cultivation of plants without the need for any additional fertilizer.

Nevertheless, there is much to be done in automation and control technology in this area to achieve the best results in both quantitative and qualitative terms of the product. This applies especially to horticultural crops that are sensitive to the cultivation environment and microclimate. This work aims to characterize the microclimate parameters in a confined agricultural environment with perforated ducts for air conditioning supply. For this work, a microclimate control unit was used instead of a lettuce crop. It was placed into a confined agricultural environment at different locations in the space to obtain the main microclimate parameters. After setting the input of the microclimate environment, the instrument measured a series of physical quantities (temperature, radiant temperature, humidity, and air velocity). Tests were carried out by taking the optimum day temperature constant for growing lettuce and by varying the supply airflow rate by setting the fan speed at 30%, 50%, and 80%. The results of these tests are essential for performing real-time control of the microclimate environment and for managing parameters for optimization of the entire system. In addition, the air velocity test showed adequate velocity reduction and good air mixing. The values obtained are generally acceptable for indoor cultivation and the conditions created are suitable for growing plants in such an environment. Light is an essential need for plants so that plants can carry out the photosynthesis process properly. In indoor DWC hydroponics system, the source of UV light is LED lights for plants. Some of the advantages of using LED light include a small light spectrum, less heat production, low power consumption, and wavelengths of 660 m and 450 m that are needed by plants. This research project aims to create a DWC hydroponic system for growing red lettuce in an indoor hydroponics and see the effect of LED grow light on the growth of red lettuce. DWC hydroponics uses AB-Mix nutrients that are channeled through inch PVC pipes using pump power. The hydroponic rack used has a height of 1.7 m and a width of 40 cm and has 3 shelves, where each shelf has 9 nutrient containers. The red lettuce plants in the DWC system were provided with different light treatments by installing shading nets with different percentages of light penetration, namely, 75%, 50%, and 0%. From the results of these treatments, the average yield of red lettuce was 300 grams on the top shelf, 400 grams on the middle shelf, and 600 grams on the bottom shelf.

This study was conducted to determine the optimal temperature difference in day–night indoor cultivation conditions to enhance the flower yield and functional component contents of female hemp plants. Hemp clones were cultivated under five distinct day and night temperature differences (DIF) during the reproductive stage. The daytime and nighttime temperature settings were as follows: 18:30 °C (negative 12 DIF), 21:27 °C (negative 6 DIF), 24:24 °C (0 DIF), 27:21 °C (positive 6 DIF), and 30:18 °C (positive 12 DIF). Seven weeks after transplantation, the growth parameters, leaf gas exchange, total phenolic compounds, 2,2-diphenylpicrylhydrazyl scavenging activity, and cannabinoid contents were analyzed. The total shoot biomass based on dry weight was highest at 21:27, reaching 41.76 g, and lowest at 30:18, measuring 24.46 g. However, the flower biomass, which is the primary production site, was highest at 24:24 and lowest at 18:30, showing a 4.7-fold difference. The photosynthesis-related parameters were temperature-dependent and strongly correlated with biomass production. The cannabinoid content of the hemp leaves increased at 21:27, whereas that of the hemp flowers increased at 27:21. The findings of this study indicate that the optimal temperature condition for female hemp flower production in a limited space is positive 6 DIF treatment, which corresponds to 27:21 °C. These results can contribute to advancements in indoor crop cultivation technology.

Full textAbstract:
Stevia rebaudiana cultivated in non-native tropical conditions tends to flower early, halting vegetative growth, resulting in lower biomass and yields of its valued steviol glycoside metabolites. While indoor cultivation allows manipulation of artificial lighting to mimic optimal conditions, it introduces an additional energy cost. The study objectives were to assess photoperiod manipulation as a lighting strategy to increase overall biomass and metabolite yields as well as to improve the efficacy of the electrical energy used for indoor cultivation of Stevia rebaudiana in non-native environmental conditions. Stevia was grown under artificial lighting with red, green, and blue wavelengths with photoperiods of 8 h, 12 h, 16 h, and intermittent light amounting to 16/24 h, each with a constant Daily Light Integral (DLI) of 7.2 mol m−2 day−1. Yield was measured as leaf dry weight biomass in combination with Liquid chromatography–mass spectrometry (LCMS) analysis of Stevioside and Rebaudioside A content. The photon flux density of the artificial and natural light as measured by a spectroradiometer, and the energy use data collected with a three-phase power quality logger, were compared for each treatment tested and to that from plants grown under natural light irradiation in a greenhouse. Yield and energy data were used to determine the efficacies of the lighting systems tested. Stevia plants under a continuous 16-h photoperiod (16H) had the highest productivity, resulting in the highest biomass accumulation and metabolite concentrations. The Stevioside and Rebaudioside A yields per plant were 975% higher than those obtained under natural daylight and day-neutral tropical photoperiod. Overall energy use and photon conversion efficacies were also highest under 16H at 65.10 g kWh−1 for biomass accumulation, 12.40 g kWh−1 for metabolite yields and 7.5 mg mol−1 for photon conversion. These findings support the application of photoperiod manipulation as a viable approach to increase productivity and improve energy use efficacies for indoor cultivation of Stevia rebaudiana plants under artificial lighting in non-native environments with the 16-h photoperiod under red and blue artificial light supplemented with green spectrum as the best option.

Full textAbstract:
Light is a key factor that affects phytochemical synthesis and accumulation in plants. Due to limitations of the environment or cultivated land, there is an urgent need to develop indoor cultivation systems to obtain higher yields with increased phytochemical concentrations using convenient light sources. Light-emitting diodes (LEDs) have several advantages, including consumption of lesser power, longer half-life, higher efficacy, and wider variation in the spectral wavelength than traditional light sources; therefore, these devices are preferred for in vitro culture and indoor plant growth. Moreover, LED irradiation of seedlings enhances plant biomass, nutrient and secondary metabolite levels, and antioxidant properties. Specifically, red and blue LED irradiation exerts strong effects on photosynthesis, stomatal functioning, phototropism, photomorphogenesis, and photosynthetic pigment levels. Additionally, ex vitro plantlet development and acclimatization can be enhanced by regulating the spectral properties of LEDs. Applying an appropriate LED spectral wavelength significantly increases antioxidant enzyme activity in plants, thereby enhancing the cell defense system and providing protection from oxidative damage. Since different plant species respond differently to lighting in the cultivation environment, it is necessary to evaluate specific wavebands before large-scale LED application for controlled in vitro plant growth. This review focuses on the most recent advances and applications of LEDs for in vitro culture organogenesis. The mechanisms underlying the production of different phytochemicals, including phenolics, flavonoids, carotenoids, anthocyanins, and antioxidant enzymes, have also been discussed.

In recent years, there has been an explosion in the number of commercial plant tissue culture (TC) units in India. More than 25 such companies have production capacity of two to five million plants per annum. Almost all units are export oriented, but the target crops are the same. Indoor foliage plants dominate the export market. Micropropagation industry in India is providing major support to Indian agriculture in four crop groups: Fruits, ornamentals, spices, forestry/plantation crops. Banana is the largest selling TC fruit crop. TC papaya plants are now marketed for extraction and processing of papain. TC anthuriums, orchids, and gerberas have attained commercial importance. TC rose plants are used as pot plants. Nearly 500 ha are under TC cardamom cultivation in southern India recording 20% to 30% increase in yield. Vanilla cultivation is expected to increase from the existing 50 ha to more than 400 ha in the coming years using TC plants. Sugar companies have in-house units for micropropagation of sugarcane. There is demand for bamboo and eucalyptus for selective reforestation. The TC Industry is constrained by the non-availability of international varieties, high infrastructure and electricity costs, and lack of managers with commercial experience. A shake-up is imperative, during which many of the existing TC units may not survive the year 2000.

Background and objective: In order to develop basic data for horticultural education and activities for college students struggling to overcome various stress and practical problems, this study is designed to understand the actual conditions of college students' horticultural experience, knowledge, and preferences.Methods: First, the experiences of horticultural activities were classified and analyzed using Google Forms. At this time, the horticultural experience was investigated by dividing it into whether there was a plant cultivation experience, a personal plant experience, and plant purchase experiences. Second, gardening activities and knowledge and preference were analzed. Third, the correlation between plant experience and plant knowledge was analyzed, and a factor analysis was conducted to determine preferred horticultural activities and class programs.Results: In the case of experiencing plant cultivation, there was a high interest in companion plants, understanding plant management methods, preventing pests, packaging or storage methods of flowers, and social media related to plants. In the case of no experience in plant cultivation, plant indifference, difficulty in cultivation, and mental and time leisure were cited as conditions for plant cultivation. While personal plant purchasing experience is about two to three times a year, gift purchasing experience was very high, and the reason why flowers were not purchased except for gifts was because they were discarded or did not know how to store them. Plant knowledge, such as plant types, names, and breeding methods, was very low, but plant terriers showed high interest, and preferences for flower plants, foliage plants, succulent plants, and fine dust removal plants and gardens, gardens, and plantation activities were high. "Plant experience" was highly connected with the latest knowledge such as "understanding fine dust plants" (<i>p</i> < .001), especially "plant interest" was highly connected with all the horticultural knowledge presented (<i>p</i> < .001). As a result of the arithmetic factor analysis, the rotational factor analysis of the six factors showed the highest number of "plant activity" types, and the factor load was important in the order of flower complex tour, plant shop tour, water cultivation, terrarium, and indoor gardening activities. The second factor was "horticulture and horticultural activities," and the factor load was high in the order of correctional care, garden care, gardening, herb raising, and vegetable raising activities.

Indoor vertical hydroponics is one of the most recent agricultural technologies to be introduced as it is a method of growing plants in vertically stacked layers using water and nutrient solution instead of soil. When cultivating such a system, the technique used to utilize and maintain the quality of water and nutrients is critical for plant growth. Additionally, the use of LED growth lights has a significant effect on plants. Despite developments in LED lighting and IoT-based smart agriculture systems, there is a lack of information on the use of LED lighting for hydroponically grown crops in vertical culture, due to the fact that vertical agriculture is a relatively new field of study. Thus, the aim of this research was to develop an IoT-based agricultural system to automated control LED-based artificial lighting on crop cultivation, as well as to explore the effects of different LED light on plant growth. In terms of the IoT-based system, numerous sensors were installed and monitored to measure the pH, EC, and other parameters. Using the Blynk application, those who can remotely control the LEDs and monitor the entire sensor and actuator. As for the effects of LED light, particularly the red and blue light, we utilize a case study of three LED grow light models from the manufacturer as light treatments for cultivating green leaf lettuce (Lactuca sativa). The result showed that increased R light (R/B = 2:1) resulted in an increase in plant height, leaf width, and leaf length on both harvesting days (10 and 20 DAT). The lettuce plant shape and size signify that the lettuces in each tier are of good standard and comparable in size.

An environmental chamber is a specialistic device used for testing effects of given controlled conditions on a variety of objects. In case of plant growth chambers, the conditions are controlled usually for plant cultivation and propagation or botanical examination undertaken on living plant material. The aim of the project was to design and build a prototype of a desktop device with a control system capable of being used as a chamber supporting plant cultivation and propagation processes by the means of partial automation of environment control. The conditions controlled in the chamber are based on the environmental requirements of plant genera, such as Heliamphora, Drosera, Orectanthe, Cyrilla, Stegolepis, Maguireothamnus, or Utricularia. These plants occur naturally in the Guiana Highlands region of Venezuela, Brazil, and Guyana, especially around the upper parts of table-shaped mountain massifs called tepuis. The chamber was designed to simulate some of the peculiar natural factors and phenomena occurring in the high-tepui and surrounding mid-elevation wetland habitats, being the most significant for amateur-level plant cultivation, keeping the design as simple and low cost as possible. It was proven on the basis of the results of several tests made during the evaluation phase that the designed prototype of the chamber operates in a satisfying way, providing basic functionality matching the base assumptions.

Ensuring the required microclimate parameters of a cultivation structure, including indoor air temperature, relative humidity, and soil surface temperature, plays a crucial role in obtaining a rich harvest of vegetables and fruits in the winter season. Creating favourable conditions for growing plants in the protected ground is possible only by using modern, high-tech heating systems that will compensate for heat energy losses and maintain a set temperature regime in the room. Gas-fired radiant heating is one such system. This heating method, using ceiling gas infrared emitters as heat sources, directs the required heat flux directly to the soil surface. At the same time, direct or indirect emissions of harmful substances into the environment are minimal, and due to the absence of heat losses during heat production and heat carrier transportation, this type of heating is effective from both energy-saving and economic points of view. The article investigates the influence of meteorological, aerodynamic, heat engineering, and other factors on the air temperature in a cultivation structure under gas-fired radiant heating conditions using a developed software calculation method. An analysis is performed, and explanations are given for the nature of the change in indoor air temperature depending on the changing environmental conditions—the example of the industrial greenhouse “Farmer 7.5” (Russian Federation).

It was made in order to understand the current trends of Green Urbanism and in particular regarding the diversity of floral and ornamental arrangements used in the design of modern interiors of public spaces. The aim of the article is to grasp current trends of Green Urbanism regarding the diversity of floral and ornamental arrangements used in the design of modern interiors of public premises. Cross-cultural comparative methods have been used, partially using the hermeneutics of old-printed texts in accordance with the modern system of scientific knowledge. The historical antecedents of ornamental gardening, horticulture, forestry and vegetable growing, new trends in the ornamental plants cultivation, modern aspects of Green Urbanism are discussed. The need for the introduction of indoor plants in the residential and office premises interiors is argued in order to create a favorable atmosphere for work and leisure. The extreme importance of selecting an assortment and developing environmentally friendly ways to increase the resistance of indoor plants against pathogens and pests in conditions of insufficient lighting, humidity, abnormal fluctuations in air temperature, etc. has been revealed. In conclusion, the world experience in the use of ornamental garden plants testifies to the eternal desire of man for unity with nature, which is especially growing in conditions of progressive urbanization. The current global trends of Green Urbanism are of particular importance in Ukraine in terms of the Ukrainian public aspirations to integrate the state into the European community.

The impacts of different growing substrate compositions, consisting of peat (PM), peat substituted with 30% green fibre (G30) and coco coir fibre (CC) growth media, were investigated in regard to the plant height, biomass and floral yield, biomass nitrogen (N) content, root growth, and cannabidiol content (CBD/A) of two phytocannabinoid-rich cannabis genotypes in an indoor pot cultivation system. Genotypes and substrate treatment combinations were randomly allocated to 36 plants according to a Latin square design. The results showed a higher total plant height for PM (39.96 cm), followed by G30 (35.28 cm), and the lowest in CC (31.54 cm). The N content of leaves indicated the highest values for plants grown in G30 (52.24 g kg DW−1), followed by PM (46.75 g kg DW−1) and a significantly lower content for CC (37.00 g kg DW−1). Root length density (RLD) increased by 40% (PM) and 50% (G30), compared to CC treatments, with no significant differences in root dry weight. Both genotypes, Kanada (KAN) and 0.2x, reacted in a genotype-specific manner. KAN indicated a reduced floral yield of plants grown in G30 (4.94 g plant−1) and CC (3.84 g plant−1) compared to PM (8.56 g plant−1). 0.2x indicated stable high floral yields of 9.19 g plant−1 (G30) to 7.90 g plant−1 (CC). Leaf DW increased in PM (5.78 g plant−1) and G30 (5.66 g plant−1) compared to CC (3.30 g plant−1), while CBD/A content remained constant. Due to a higher biomass yield, the CBD/A yield of flowers (549.66 mg plant−1) and leaves (224.16 mg plant−1) revealed 0.2x as an interesting genotype for indoor pot cultivation in a peat-based substrate substituted with 30% green fibres. Overall, the demand for organic green fibres to partly replace fractionated peat showed a genotype-specific option for a homogeneous plant development, with comparable high biomass yields and stable cannabinoid contents compared to a peat containing standard substrate.

Full textAbstract:
Cannabis sativus L. is an annual, deciduous, dimorphic, flowering plant that is distributed all over the world. Despite its tremendous and handy usage in medicinal and other areas, the cultivation, production, and trade of cannabis are illegal in most of the countries. It is so because of some of its harmful side effects on human health when consumed haphazardly or addictively. Following the declaration made by the UN Assembly, some countries, including the Republic of South Africa, Canada, Germany, Australia, Colombia, and Indonesia, have legalized the indoor cultivation and production of cannabis, as well as cannabis-based products. Cannabis can thrive in a wide range of climatic and ecological conditions. Cannabis can be propagated via seeds, cuttings, grafting, micropropagation, etc. The plants are mainly cultivated for their chemical constituents like tetrahydrocannabinol (THC), cannabidiol, cannabinol, etc., which are extracted from their dried flowers. This study illustrates the production technology, current legal status, and botanical characteristics of Cannabis sativus.

Full textAbstract:
Tomato (Solanum lycopersicum Mill.) is one of the widely cultured vegetables under protected cultivation, in which insufficient light is one of the major factors that limit its growth, yield, and quality. Chlorophyll b (Chl b) is exclusively present in the light-harvesting complex (LHC) of photosystems, while its synthesis is strictly regulated in response to light conditions in order to control the antenna size. Chlorophyllide a oxygenase (CAO) is the sole enzyme that converts Chl a to Chl b for Chl b biosynthesis. Previous studies have shown that overexpressing CAO without the regulating domain (A domain) in Arabidopsis overproduced Chl b. However, the growth characteristics of the Chl b overproduced plants under different light environmental conditions are not well studied. Considering tomatoes are light-loving plants and sensitive to low light stress, this study aimed to uncover the growth character of tomatoes with enhanced production of Chl b. The A domain deleted Arabidopsis CAO fused with the FLAG tag (BCF) was overexpressed in tomatoes. The BCF overexpressed plants accumulated a significantly higher Chl b content, resulting in a significantly lower Chl a/b ratio than WT. Additionally, BCF plants possessed a lower maximal photochemical efficiency of photosystem II (Fv/Fm) and anthocyanin content than WT plants. The growth rate of BCF plants was significantly faster than WT plants under low-light (LL) conditions with light intensity at 50–70 µmol photons m−2 s−1, while BCF plants grew slower than WT plants under high-light (HL) conditions. Our results revealed that Chl b overproduced tomato plants could better adapt to LL conditions by absorbing more light for photosynthesis but adapt poorly to excess light conditions by accumulating more ROS and fewer anthocyanins. Enhanced production of Chl b is able to improve the growth rate of tomatoes that are grown under LL conditions, indicating the prospect of employing Chl b overproduced light-loving crops and ornamental plants for protected or indoor cultivation.

Full textAbstract:
Over the last several decades, plants have been developed as a platform for the production of useful recombinant proteins due to a number of advantages, including rapid production and scalability, the ability to produce unique glycoforms, and the intrinsic safety of food crops. The expression methods used to produce target proteins are divided into stable and transient systems depending on applications that use whole plants or minimally processed forms. In the early stages of research, stable expression systems were mostly used; however, in recent years, transient expression systems have been preferred. The production of the plant itself, which produces recombinant proteins, is currently divided into two major approaches, open-field cultivation and closed-indoor systems. The latter encompasses such regimes as greenhouses, vertical farming units, cell bioreactors, and hydroponic systems. Various aspects of each system will be discussed in this review, which focuses mainly on practical examples and commercially feasible approaches.

Full textAbstract:
Proper waste management has been emergent attention in varied human habitats. Following the best practices for waste management is essential for a sustainable living environment. This research work proposes a technology-supported self-sustainable aquaponics environment that automatically manages and controls the system by integrating with IoT technology and Naive Bayes algorithm for automated fish feeding. Water quality is monitored with sensors such as pH, temperature, humidity, dissolved oxygen, and water level sensors. Solid waste of fish is filtered and the nitrification process has been carried out by bio-filter. The water level of the fish tank is monitored and maintained by an auto system. Fish feeding requirements have been attained using ML model. The nutrient film technique-based planting system optimally extracts nutrients. The Vertical farming technique helps to reduce the land and water used for cultivation. The sensors are operated on microcontrollers namely Arduino UNO and Raspberry Pi. The sensed values are communicated through a mobile application for constantly monitoring the aquaponics environment. The prospect shows the self-sustainable smart aquaponic platform for farmers to grow fish and plants in a single system simultaneously to get increased production with fewer natural resources such as land and water.

Full textAbstract:
Urban lifestyle is identical to stressful life and sedentary habit, leading to the increase of chronic conditions such as diabetes and cardiovascular-related diseases. Antioxidants are renowned for maintaining cellular function by quenching radicals produced in stressful conditions or infection. Fresh fruits and vegetables are the primary sources of antioxidants, but the long postharvest and transport system may reduce the benefits for the urban population. Hence, we designed a cultivation method to produce wheatgrass microgreens with high antioxidants in an urban indoor farming system. Generally, plants require light at the wavelength of 663 and 642 nm (red) and 430 nm and 453 nm (blue) to allow photosynthesis and production of secondary metabolites, such as antioxidants. We applied the LED lights with an RGB ratio of 91R/9B, 83R/17B, 47R/53B, 35R/65B, and white florescent as the control. Our results showed that 91R/9B reduced fresh mass and chlorophyll content, which might be due to the suppression of photosynthesis capacity. Interestingly, we found a significant (p<0.05) increase in carotenoids and flavonoid contents due to light combinations of 35R/65B and 83R/17B, respectively. However, the total antioxidants capacity was similar among all treatments. Carotenoids and flavonoids are among the antioxidants with a significant role in decreasing the risks of chronic diseases and their potential as antiviral agents. This cultivation system of wheat microgreen could be a promising solution to routinely supply carotenoids and flavonoids to the urban population. Further, it is also considered more environmentally friendly as it could be performed in a limited amount of land (vertically) and potentially use less energy for distribution.

Chili plants are one of the horticultural commodities that have economic value and are widely planted in Sungai Geringging Village, Kampar Kiri District, Kampar Regency. The main obstacle in achieving the quantity and quality of chili production is the attack of pests and diseases. This service aims to provide knowledge to chili farmers in Sungai Geringging Village about the types of pest and disease that attack chilies, symptoms of attack, and methods of control. The extension methods are lectures, questions and answers, discussions, demonstrations and practices with regard to chili plants. Extension is in the form of indoor presentation using LCD and in-focus tools by demonstrating the types of pest and disease that attack chilies and their attack symptoms, discussion and question and answer about pests and diseases of chili plants and their control techniques. Service programs in the form of counseling and demonstrations have been very well responded by chili farmers, counseling and demonstrations with material on how to introduce and control chili pests have never been received, plus in the cultivation of chili plants the obstacles that are often faced by farmers are problems with pests and diseases therefore participating farmers pay closer attention.

Pre-Cultivated under LEDs—Possible Mitigation Treatments and Their Energy Consumption." Forests 11, no. 3 (March 21, 2020): 354. http://dx.doi.org/10.3390/f11030354.
Full textAbstract:
Year-round cultivation under light emitting diodes (LEDs) has gained interest in boreal forest regions like Fenno-Scandinavia. This concept offers forest nurseries an option to increase seedling production normally restricted by the short vegetation period and the climate conditions. In contrast to some horticultural crops which can be cultivated entirely under LEDs without sunlight, forest seedlings need to be transplanted outdoors in the nursery at a very young age before being outplanted in the field. Juvenile plants are less efficient using absorbed light and dissipating excess energy making them prone to photoinhibition at conditions that usually do not harm mature plants. The outdoor transfer can cause stress in the seedlings due to high sunlight intensity and exposure to ultraviolet (UV) radiation not typically present in the spectra of LED lamps. This study tested possible treatments for mitigating light shock stress in seedlings of Picea abies (L.) Karst. and Pinus sylvestris L. transplanted from indoor cultivation under LEDs to outdoor sunlight exposure. Three sowings were carried out in 2014 (May and June) and 2015 (May) cultivating the seedlings during five weeks under LED lights only. Afterwards, higher light intensity or UV radiation treatments were applied during one week in order to adapt the seedlings to natural outdoor conditions. After transplanting a transition phase was introduced using shading cloths for one or three weeks as outdoor treatments for light shock mitigation. Chlorophyll fluorescence (ChlF) levels and CO2 assimilation rates were measured before transplanting and followed outdoors during 5 weeks. The ChlF results revealed stress symptoms in the photoreceptors during the first days after transplanting. After five weeks outdoors the ChlF levels had recovered and the light saturation points had shifted, allowing higher CO2 assimilation rates. By the end of the vegetation period the morphological attributes showed no major differences between treatments.

Full textAbstract:
Optical Camera Communication (OCC) systems have a potential application in microalgae production plants. In this work, a proof-of-concept prototype consisting of an artificial lighting photobioreactor is proposed. This reactor optimises the culture’s photosynthetic efficiency while transmitting on-off keying signals to a rolling-shutter camera. Upon reception, both signal decoding and biomass concentration sensing are performed simultaneously using image processing techniques. Moreover, the communication channel’s theoretical modelling, the data rate system’s performance, and the plant distribution requirements and restrictions for a production-scale facility are detailed. A case study is conducted to classify three different node arrangements in a real facility, considering node visibility, channel capacity, and space exploitation. Finally, several experiments comprising radiance evaluation and Signal-to-Noise Ratio (SNR) computation are performed at different angles of view in both indoor and outdoor environments. It is observed that the Lambertian-like emission patterns are affected by increasing concentrations, reducing the effective emission angles. Furthermore, significant differences in the SNR, up to 20 dB, perceived along the illuminated surface (centre versus border), gradually reduce as light is affected by greater dispersion. The experimental analysis in terms of scattering and selective wavelength attenuation for green (Arthrospira platensis) and brown (Rhodosorus marinus) microalgae species determines that the selected strain must be considered in the development of this system.

Full textAbstract:
The production cost of greenhouse cultivation depends mainly upon significant amounts of energy consumption in order to keep the optimum environmental condition for plant growth. Τhe expenditure on energy, either for heating or cooling, ranges between 30% to 60% of the total production costs, and any attempt to save energy will result in a positive effect on the potentiality of production accordingly, affecting the greenhouse product prices. Research has shown that CO2 enrichment in greenhouses significantly increases the yield of most indoor cultivation of plants of the C3 category. For these plants, when the CO2 concentration increases by three times above that of the atmosphere (380 ppm), the optimum plant growth temperature shifts higher by 5 °C to 10 °C reaching up to 30 °C to 32 °C. Therefore, huge amounts of solar energy can be captured inside the greenhouses, as the ventilation can be decreased. Alongside this, the use of a simple passive solar system consisting of plastic sleeves filled with water is considered to be an improved way to increase the energy inside greenhouses. In this work, three experimental trials were conducted to examine the benefit of the solar energy captured inside a greenhouse during CO2 enrichment at high temperatures. Finally, a modeling approach based on the heat loss equation was developed in order to establish the energy saving inside the greenhouses under the circumstances mentioned.

Full textAbstract:
An enumeration of the genus Dendrobium Sw. (Orchidaceae) in Manipur, India was attempted. Literature review revealed the occurrence of 67 species under the genus from the state. The study was carried out through repeated field explorations in different natural forests of Manipur since 2012. Out of the total taxa reported from the state, only 42 species could be traced in the field. All these taxa are presented here with their flowering phenology and places of occurrence. Twenty-five species were untraceable in the field; however, nine species out of these 25 are represented by authentic herbarium specimens and supported by published documents. The remaining 16 species were reported only in literature, but no live plants or herbarium specimens were found. Out of the 42 species inventoried from the field, many taxa are under threat owing to habitat loss due to felling of trees, deforestation, and ‘jhum’ cultivation. So, there is an urgent need of conservation of those species through in situ and ex situ means for their sustenance. A photographic plate of some taxa is provided here which might be useful for their easy identification in the field and for taking care of their conservation. Large-scale uses of these species as cut flowers and indoor & outdoor plants may be practised through micropropagation and cultivation in nurseries which may help in revenue generation for the state.

Pak choi is a group of plants in the mustard family. The production factors affecting pak choi cultivation are seeds, nutrients, and pesticides. This study aimed to (1) test the seed viability and vigor of two pak choi cultivars and (2) determine the effect of different cultivars on the growth and yield of pak choi plants. The plant cultivars used in this study are ‘Brisk Green’ and ‘Nauli’. Viability and vigor testing of two pak choi cultivars showed no significant differences between pak choi cultivar ‘Brisk Green’ and cultivar ‘Nauli’ in the viability of seeds, with the percentage of Maximum Growth Potential (MGP) being 95.5 and 97.0%. Germination Potential (GP) was 86.5 and 84.0%. The vigor of seeds showed that the Seed Vigor Index (SVI) was 84.5 and 81.5%, and the Speed of Gemination (SG) was 12.4 and 12.0% at 5-7 days after sowing. Evaluation of plant growth showed that Pak choi cv. ‘Nauli’ has the highest number of leaves and fresh weights than ‘Brisk Green’, and it showed more resistance to watery soft rot due to the fungus of Sclerotinia sclerotiorum. This experiment also showed that growing plants in the indoor hydroponic planting system could be prospective for developing pak choi plants.

Full textAbstract:
A reduction in crop productivity in cultivable land and challenging environmental factors have directed advancement in indoor cultivation systems, such that the yield parameters are higher in outdoor cultivation systems. In wake of this situation, light emitting diode (LED) lighting has proved to be promising in the field of agricultural lighting. Properties such as energy efficiency, long lifetime, photon flux efficacy and flexibility in application make LEDs better suited for future agricultural lighting systems over traditional lighting systems. Different LED spectrums have varied effects on the morphogenesis and photosynthetic responses in plants. LEDs have a profound effect on plant growth and development and also control key physiological processes such as phototropism, the immigration of chloroplasts, day/night period control and the opening/closing of stomata. Moreover, the synthesis of bioactive compounds and antioxidants on exposure to LED spectrum also provides information on the possible regulation of antioxidative defense genes to protect the cells from oxidative damage. Similarly, LEDs are also seen to escalate the nutrient metabolism in plants and flower initiation, thus improving the quality of the crops as well. However, the complete management of the irradiance and wavelength is the key to maximize the economic efficacy of crop production, quality, and the nutrition potential of plants grown in controlled environments. This review aims to summarize the various advancements made in the area of LED technology in agriculture, focusing on key processes such as morphological changes, photosynthetic activity, nutrient metabolism, antioxidant capacity and flowering in plants. Emphasis is also made on the variation in activities of different LED spectra between different plant species. In addition, research gaps and future perspectives are also discussed of this emerging multidisciplinary field of research and its development.
