Full textAbstract:
The present paper discusses about the status of Hitech floriculture industry in India. The present status of commercial floriculture industry is discussed. Alongwith this, the problems and prospects of the industry is are highlighted. The floriculture industry is characterized by traditional as well as modern cut flowers. The cutflower industry is rapidly growing worldwide. While this industry is dominated by selected European countries as well as US and Japan, the production base is shifting from these countries to low cost countries like Kenya, Colombia, India and China. While much needs to be done, Indian floriculture industry has lot of potential of growth. The consumption within India is increasing with changing socio economic structure as well as effects of globalization. At the same time, India is preparing itself to take an increasing role in the world trade of floriculture, which at present is miniscule. The government has recognized the importance of this industry and hence given a special focus to this industry. The National Horticulture Mission is an endeavor of the government to promote holistic development of floriculture and with an integrated approach towards cluster development.

In recent years, the commercial greenhouse industry has begun to implement sustainable production practices. However, floriculture certification programs for sustainable production practices are a relatively new phenomenon in the United States. Between July and Oct. 2008, a commercial floriculture grower survey was conducted to determine potential barriers to sustainable floriculture certification. Using a logistic regression model, seven potential areas were evaluated: risk, profitability, economic viability, prior experience, education, operation size, and customer types. Although respondents had positive attitudes toward sustainability and had adopted sustainable practices, respondents had little knowledge and interest in U.S. certification.

Full textAbstract:
Plastic products have revolutionized commercial floriculture. Even plastic flowers have caused a new marketing consideration because they are quite competitive with the marketing of live material. Plastic pots are used widely because they are lightweight, attractive, and relatively inexpensive. Plastic flats and trays have been readily accepted by the consumer, and were instrumental in the development of plug culture. Major components of automatic watering systems are made of plastic, and much of the plumbing practiced in commercial floriculture is done with plastic pipe and fittings. Plastic foams are used in floral arrangements, growing media, and propagation cubes or strips. Plastic is used to make steam-sterilization covers, shading material for the manipulation of both light intensity and photoperiod, and mulches or ground covers to help control weeds. Very large quantities of plastic are used in commercial floriculture, and recent landfill restrictions have necessitated procedures for recycling. Recycling procedures are known, but logistics and economics of recycling have not been resolved completely.

Full textAbstract:
Filled with caustic statements on artificial plant breeding and florist flowers, John Ruskin's botanical essay collection, Proserpina (1875–86), advances a cogent argument against commercial floriculture and, by extension, the commodification of vegetal life. However, the eco-political stakes of this text have received limited attention. Past studies have primarily interpreted Proserpina as a testament to Ruskin's disquiet about Darwinism and as a memorial to his late love, Rose La Touche. In this article, I argue that beneath these scientific and personal imperatives, Proserpina urges readers to resist the consumption of floral commodities engineered by Victorian nurserymen and florists. My reading draws together the history of nineteenth-century flower breeding with recent inquiries from the field of critical plant studies in order to illuminate how Ruskin's botanical prose dovetails with present-day debates on vegetal ethics. Flower-breeding motifs figure prominently in a series of letters written for Proserpina by Rose's mother, Maria La Touche, whose contributions to this book have long been overlooked. Analyzing Proserpina's floricultural subtext will not only recover La Touche's letters from the shadow of Ruskin's love life but also underscore an unexplored facet of Ruskin's antipathy toward Darwin, who celebrated florist flowers in his own botanical writings.

AbstractRoses are the most important crop in the floriculture industry and attract both pollinators and human admirers. Until now, a lot of research focusing on postharvest physiology including flower senescence has been conducted, leading to improvement in vase life. However, few studies have focused on the physiology of petal growth, the perception of light by petals, and the relationship between petal growth and environmental conditions. Regarding roses, whose ornamental value lies in the process of blooming from buds, it is also important to understand their flowering mechanisms and establish methods to control such mechanisms, as well as focus on slowing the aging process, in order to achieve high quality of postharvest cut roses. Elucidation of the mechanisms of rose flower opening would contribute to enhanced quality and commercial production of floricultural crops as well as greatly advance basic scientific knowledge regarding plant biology. In this review, we describe the progress and future prospects in the study of petal growth physiology of cut roses.

Full textAbstract:
A soil moisture sensor-based automated irrigation system was trialed in a commercial floriculture greenhouse to determine what benefits these types of systems may offer to herbaceous ornamental producers. Water use, crop quality and growth, and grower behavior toward adoption of the new technology were monitored, when all decision making related to system operation was carried out by the grower. Two cultivars of poinsettia (Euphorbia ×pulcherrima) and three cultivars of geranium (Pelargonium ×hortorum) were produced in side-by-side trials over the course of 2 years while comparing grower-controlled, sensor-based automated irrigation with traditional grower-managed (timer-based) irrigation. Plant quality was equivalent between irrigation treatments across all five trials. Differences in plant size were noted in four of the five trials between irrigation treatments, but in all instances these differences were not judged by the commercial grower to impact marketability of the crop. No reductions in irrigation water use were noted with the sensor-based irrigation system, which differed from previous research using this technology in ornamental production. Over the course of 2 years, the number of plants produced using sensor-based irrigation control was scaled up, indicating increasing confidence in, and adoption of, the technology. Managers at the facility found that sensor-based irrigation facilitated reallocation of labor from irrigation management, which was especially valuable during peak production and shipping periods. The payback period calculated from labor savings would be roughly 1.5 years if the sensor-based irrigation system was implemented throughout the facility.

Full textAbstract:
ABSTRACT Tropical floriculture has increased significantly in the last decade due to a growing worldwide market trend of consuming exotic, colorful, beautiful and durable flowers. Among the tropical floriculture products, ornamental gingers, species belonging to the families Zingiberaceae and Costaceae, have high potential for ornamental use, both for landscaping, for cut and potted flower and foliage. However, little information can be found in literature when it comes to crop fertilization, mainly concerning nitrogen fertilization, quite important to tropical soils which are poor in organic matter resource. Thus, this study aimed to evaluate application of nitrogen doses, using fertigation for growing ornamental ginger under protected cultivation. The experiment was carried out from 2012 to 2016, using seedlings produced in vitro multiplication. Plantlets remained for a period of acclimatization in a nursery and, then were planted in pits spaced 1x1 m in a greenhouse. The agronomic parameters and recommendation of nitrogen using SPAD were evaluated from the beginning 2013 until 2016. The experimental arrangement was in randomized blocks with five nitrogen doses (0, 100, 200, 300 and 400 kg ha-1) and 4 replicates. The increase of nitrogen doses, up to 400 kg ha-1 via fertigation, produces 77 100-cm-height commercial flowers/tussock/year, favoring the commercial production and standardization of ornamental ginger.

Full textAbstract:
The article aims at an introductory exploration of the theme of sustainability in Brazilian floriculture, both in its segment of cut flowers and foliage and in landscaping. The study is based on bibliographic review, data collection and interpretation on the recent performance of the flower and ornamental plants market in Brazil, with emphasis on the role played by the importation of genetic material from exotic species to support commercial activity in the country. From this phenomenon and the productive and distributive concentration of the flowers and plants in the State of Sao Paulo (Holambra, Santo Antônio de Posse, Campinas, Atibaia and Mogi das Cruzes), discusses the national homogenization of taste and consumption habits and requirements for adapting exotic species. In the end, the research points to future ways of investigating the potential of native species exploration in favor of better results for the environmental and socioeconomic sustainability of the floriculture and ornamental plants sector in Brazil.

This work aims to study the panorama of the floriculture and ornamental plants sector in Brazil, highlighting the main aspects related to area, production and distribution in the national scenario and consumption, the material used to obtain the data regarding the research carried out, was extracted from sources of research. Floriculture was an activity that was restricted only in the Southeast, more specifically in the State of São Paulo. Currently, due to the work of several institutions, this sector can be expanded to other regions of the country. Floriculture has great socioeconomic potential, generating jobs mainly for small producers. Although floriculture has great potential for expansion, it still has great difficulties due to the lack of habit of Brazilians in consuming flowers. The results showed that the domestic market generates a considerable source of income for the population in general, the ease of access of these products, makes the consumption of flowers in the country have gained more and more space, although it is very low in relation to other countries. Brazil has resulted in annual growth of 6.26% in recent years, moving around US $ 750 million per year, with a per capita consumption of US $ 4.70 and has 18,000 sales points throughout the country. The foreign market, however, has a remarkable growth, however, it needs to conquer much more space with other South American countries, corresponding to only 0.22% of the world market. Brazil exports to 40 destinations, with Holland being the largest buyer, followed by the United States. In 2011, Brazil exported US $ 20,699,521, 40.33% of which was related to ornamental plants, 48.37% for bulbs, rhizomes and similar, 3.67% fresh flowers and 7.63% of other products. It is concluded that there is a need to formulate strategies to manage in a way that the productive and commercial sectors grow in order to strengthen the market.

Full textAbstract:
Isolates of Phytophthora in floriculture crops were collected from North Carolina commercial greenhouse facilities in 2007 and 2008, identified, and characterized for mating type and mefenoxam sensitivity. In all, 163 isolates from 13 host species at 11 locations were identified primarily as Phytophthora nicotianae (59%), P. drechsleri (23%), P. cryptogea (9%), and P. tropicalis (4%). Multiple Phytophthora spp. were found at five locations. DNA sequencing was more reliable for differentiating P. cryptogea and P. drechsleri. Only the A1 mating type of P. drechsleri was collected; however, both mating types of P. nicotianae, P. cryptogea, and P. tropicalis were found. Overall, 66% of Phytophthora isolates were resistant or intermediate in resistance to mefenoxam at 1 μg a.i./ml. Three groups of P. drechsleri isolates had effective concentration of mefenoxam providing 50% growth inhibition (EC50) estimates over 700 μg a.i./ml. EC50 estimates for P. nicotianae ranged from 246 to 435 μg a.i./ml. Isolates of P. nicotianae exhibited phenotypic heterogeneity at several locations, suggesting multiple separate introductions to the facilities. In contrast, P. nicotianae and P. drechsleri isolates from two locations were phenotypically identical to a previous survey, suggesting that the facilities have Phytophthora spp. established onsite.

Full textAbstract:
Swainsona formosa (G.Don) J.Thompson (Sturt’s desert pea) is used in commercial floriculture for cut flowers and ornamental pot plants; however, accurate identification of the growth stages is critically important in making management decisions in floricultural crops. This plant was investigated by stereomicroscopy and scanning electron microscopy (SEM) to identify flowering time and stages of floral development. This is the first work to describe the complete floral ontogeny in a member of tribe Galegeae. Conversion from vegetative to reproductive stages began within 40–46 days after seed germination for axillary branches and within 46–52 days for central stems. Plants required 807.5 days °C growing degree-days for axillary branches and 921.5 days °C for central stems to reach 50% flowering. The central stem grew more nodes (11.1 ± 0.97 nodes) before the initiation of the first flower than did the axillary branches (7.2 ± 0.93 nodes). The order of floral organ initiation within each whorl is unidirectional, except for the petal whorl, which is simultaneous; the flower is organised into five whorls and shows a pentamerous arrangement of sepals and petals, 10 stamens in two whorls and a central carpel.

Full textAbstract:
Ethephon [(2-chloroethyl) phosphonic acid] is a plant growth regulator that releases ethylene on application and can abort flowers, stimulate branching, and inhibit stem elongation. Although ethephon is used as a foliar spray during the commercial production of many ornamental crops, its effectiveness as a drench has not been widely investigated. We performed experiments to quantify the effects of an ethephon drench on growth and flowering of a range of bedding plant and Narcissus cultivars and to assess the effect of lime on ethylene release from a peat substrate. A substrate drench of 0, 100, 250, or 500 mg·L−1 ethephon was applied to 12 potted Narcissus cultivars at one location, and up to 200 mg·L−1 was applied to 24 cultivars of bedding plants at three locations. Compared with untreated controls, ethephon generally reduced plant height at flowering and the effect increased with increased concentration. For example, Narcissus treated with a 250 mg·L−1 ethephon drench had stems that were 20% to 40% shorter at the end of flowering than control plants. However, ethephon drenches generally caused a 2- to 3-day flowering delay, and two cultivars had a phytotoxic response. Among the bedding plants studied, a 100-mg·L−1 ethephon drench suppressed plant height at flowering by greater than 30% in Catharanthus, Celosia, Dianthus, and Verbena, but by only 10% to 15% in Lobelia, Lycopersicon, and Tagetes. The drenches also delayed flowering in 10 of the 16 crops measured and decreased dry mass accumulation in all of the crops measured. Ethephon release from peat substrate became maximal ≈120 h after application and was dramatically increased by incorporation of dolomitic lime up to a rate of 9.5 kg lime per m3 of peat. Collectively, these studies show that ethephon substrate drenches inhibit stem elongation in a broad range of floriculture crops, but can also delay flowering and reduce biomass accumulation.

When breeding floriculture plants, one must have a targeted phenotype and genotype in mind before the initial cross-pollination event is performed. In the case of the floriculture breeding program at the University of Illinois, our initial goal was to develop a commercially acceptable, yet novel, Impatienswallerana(bedding plant impatiens) phenotype with improved resistance to the western flower thrips, Franklinella occidentalis, a significant insect pest in production greenhouses. This study describes the process used to obtain a large impatiens phenotype (>61 cm tall and >125 cm wide) with acceptable branching, leaf color, flower size, flower number, flower display, and flower colors with improved resistance to western flower thrips. A reliable and simple evaluation technique, based on the number of leaves expressing western flower thrips feeding damage after inoculation, was developed and utilized to create more resistant impatiens genotypes based on generation means. Using a 1 to 9 scale, mean damage ratings for the original germplasm populations 1, 2, and 3 were 5.18, 6.02, and 6.11, respectively, with the trend for populations 1, 2, and 3 skewed toward susceptible plants. Germplasm with novel phenotypes were derived from crosses with plants in populations 1 and 3 with commercial cultivars. These novel phenotypes had improved levels of resistance with a mean rating of 5.06 and a normal shaped distribution. The potential for improving resistance to western flower thrips feeding exists within available germplasm and the tools necessary for proper evaluations are available.

Integration of desirable traits into commercial ornamentals using genetic engineering techniques is a powerful tool in contemporary biotechnology. However, these techniques have had a limited impact in the domain of ornamental horticulture, particularly floriculture. Modifications of the color, architecture or fragrance of the flowers as well as an improvement of the plant tolerance/resistance against abiotic and biotic stresses using plant transformation techniques, is still in its infancy. This review focuses on the application of Agrobacterium-mediated transformation, a major plant genetic engineering approach to ornamental plant breeding and the impact it has had to date.

Jasmine is an important commercial flower crop in Tamil Nadu. The crop has a main floweringseason during March to October and an off-season from November to February. During thisoff-season, flowering is very poor or there is no flowering in many growing areas. In recentyears, growth regulators are valuable in floriculture for manipulating growth and flowering ofmany crops and hence and attempt has been made to induce flowering during off season usinggrowth regulators in Jasmine in the Floriculture unit of the Department of Horticulture, Facultyof Agriculture, Annamalai University, Tamil Nadu during November, 2016 to February, 2017.The treatment comprises of three concentrations of each of two growth promoting substancesviz., NAA and GA3 and two growth retardants (Cycocel and Maleic Hydrazide). The experimentwas laid out in randomized block design with three replications. Among the various treatments,application of NAA @ 75 ppm (T6) recorded the highest plant height (130.6 cm and 178.5 cm at90 and 180 DAP respectively), number of primary shoots (21.68 and 35.68 at 90 and 180 DAPrespectively), number of nodes (9.86 and 15.89 cm at 90 and 180 DAP respectively) and numberof leaves (1250.0 and 2689.5 at 90 and 180 DAP respectively). Earliness in flowering (26.38DAP) and maximum duration of flowering (171.00 days) was noticed in (GA3@ 150 ppm T3).From the above studies, it is inferred that application of GA3 @ 150 ppm could be recommendedfor enhanced growth and higher flower yield in Jasminum sambac.

Abstract Floriculture is very lucrative to small producers as it requires small land areas, with usually short production cycles. The region of Santa Catarina West in Brazil has growth potential in the cultivation of ornamental plants, although it is not practically observed, as the productive chain of this sector has little or no organization, making it imperative to study the causes of this problem. Therefore, the aim of this study was to characterize the productive chain, market, and commercialization of ornamental plants in Chapecó-SC. The proposed study was carried out in an integrated manner in Chapecó-SC, through structured interviews with farmers, traders, and consumers of flowers and ornamental plants. The study sample consisted of 45 consumers, 24 producers, and 18 commercial establishments. Only three producers of ornamental plants in Chapecó were identified among the participants interviewed, although 84% believed that the municipality has demand for floriculture products, and only 21% of the interviewees have thought about cultivating ornamental plants. The market and commercialization of flowers and ornamental plants in Chapecó are dependent highly on the supply of products from the state of São Paulo, especially form the region of Holambra. The commercialization is predominantly in supermarket chains, for ease of access to consumers. The primary factor affecting the commercialization of ornamental plants is the price, because a dearth of producers in the region leads to an increase in the price, especially due to the long transportation.

Full textAbstract:
Phytophthora isolates were collected from floriculture crops grown in commercial greenhouses in North Carolina for species identification, compatibility type determination, and mefenoxam sensitivity tests. Isolation from 41 symptomatic plant species at 29 production locations resulted in 483 isolates from eight crops at seven locations. Phytophthora cryptogea (184 isolates) was recovered from dusty miller and gerbera daisy. All isolates of P. cryptogea were insensitive or intermediate in sensitivity to mefenoxam at 1 μg a.i./ml and were A1 compatibility type. P. nicotianae (273 isolates) was isolated from African violet, lavender, pansy, petunia, and vinca. Of these isolates, 21% were insensitive to mefenoxam at either 1 or 100 μg a.i./ml. Isolates of P. nicotianae from five locations were A2 compatibility type, whereas isolates on pansy at one location were A1 compatibility type. English ivy grown at two locations was infected with P. palmivora. All 26 isolates of P. palmivora were sensitive to mefenoxam and were A1 compatibility type. Mating type and mefenoxam sensitivity were uniform among isolates of P. nicotianae and P. palmivora from a given crop at a given location, suggesting that epidemics within a location may have originated from a single source of inoculum.

Limonium sinuatum and Dianthus chinensis are plant species of great importance in Brazilian floriculture, being propagated by seed, therefore, the characteristics of the substrates used are respectable in seedlings emergence and development process. Thus, the objective of this research was to evaluate the influence of two commercial substrates on emergence and development of Limonium sinuatum and Dianthus chinensis seedlings. The experiment was conducted in a greenhouse (Pad & Fan type) at São Paulo State University. The treatments were: T1 – Basaplant® and T2 – Tropstrato®, for both species, whose seeds were germinated in expanded polystyrene trays of 128 cells, being eight replicates, containing 8 seeds/replicate. The evaluated traits were: percentage of emergence, emergence speed index, mean emergence time, shoot height, root length and seedlings fresh and dry mass. The substrate characteristics evaluated were: pH, electrical conductivity, macroporosity, microporosity, total porosity, density and water retention capacity. The experimental design was completely randomized, and data were submitted to analysis of variance to Tukey test at 5% to compare the means. The emergence of Limonium sinuatum and Dianthus chinensis were impaired, possibly due to low electrical conductivity provided by substrates. However, Basaplant® substrate favoured the development of evaluated species in relation to aerial part length, root length and total fresh and dry mass, which is recommended for using as substrate for both species.

Full textAbstract:
The evolutionary history of Phytophthora cryptogea and P. drechsleri isolates previously collected from floriculture crops in North Carolina commercial greenhouses was explored with coalescent- and parsimony-based analyses. Initially, 68 isolates representing 13 location–host groups were sequenced at multiple loci. Sequences of all isolates within a group were identical. A subset of isolates were selected, cloned to resolve heterozygous sites, and analyzed with SNAP Workbench. The internal transcribed spacer (ITS) region of the ribosomal DNA and cytochrome oxidase II gene genealogies were congruent and indicated that P. cryptogea and P. drechsleri are sister species diverged from a common ancestor with no evidence of gene flow. In contrast, genealogies inferred from β-tubulin (β-tub) and translation elongation factor 1α (EF-1α) genes were in conflict with these loci. Coalescent analysis based on a nonrecombining partition in β-tub and EF-1α showed an initial (older) split between P. cryptogea and P. drechsleri, with a later (recent) event separating the remaining P. cryptogea haplotypes from P. drechsleri. A parsimony-based minimal ancestral recombination graph inferred recombination between P. cryptogea and P. drechsleri isolates in the ITS region and β-tub, suggesting genetic exchange between species. Also, putative recombination between A1 and A2 mating types of P. cryptogea suggests that sexual reproduction has occurred in the history of these P. cryptogea isolates.

Full textAbstract:
The University of Georgia trial garden has been in existence since 1982, and the method of evaluation and distribution of taxa has evolved over the years. Annual and perennial taxa are evaluated systematically, over the entire season, providing season-long summaries for each one. Annuals are evaluated every 2 weeks, and scores are based on plant performance, including foliar health, flower numbers and the appearance of disease and insect damage. Perennials are evaluated similarly, however flowering time, flowering persistence and height in the landscape are also noted. Summaries for each taxon are presented in tabular and graphic form. Many new crops have been evaluated and introduced to the floriculture industry. New crops are placed in the horticulture gardens and evaluated by garden personnel and by commercial growers and landscapers. Plants have been distributed free of charge to propagators and growers, resulting in rapid market acceptance of successful taxa.

Full textAbstract:
Ozone treatment has many advantages for control of fungal diseases. There are no residue concerns, no registration is required, and it is non-specific, therefore potentially effective against a broad spectrum of pathogens. However, ozone is known to cause plant damage. There is little information available on either the ozone tolerance of floriculture crops or the levels required to kill plant pathogens under commercial conditions. Nine floriculture crops (begonia, petunia, Impatiens, Kalanchoe, pot roses, pot chrysanthemums, lilies, snapdragons and Alstroemeria) were subjected to increasing levels of ozone. Trials were conducted at 5 and 20 °C (90% to 95% RH) and ozone exposure was for 4 days for either 10 hours per day (simulating night treatment) or for 10 minutes every hour. Damage was assessed immediately after treatment and after an additional 3 days at room temperature in ozone-free air. Trials were terminated for the crop when an unacceptable level of damage was observed. Trials to determine the lethal dose for actively growing pathogens (Alternaria alternata, Alternaria zinniae and Botrytis cinerea) and fungal spores were conducted under identical conditions. Ozone tolerance varied with plant type and ranged between <0.2 and 3ppm. Generally, the crops surveyed were more susceptible to ozone damage at the low temperature. As a group, the bedding plants were the least tolerant. Fungal spores were killed at treatment levels between 0.8 and 2 ppm ozone. The actively growing fungal mycelium was still viable at 3 ppm ozone when the trial had to be terminated due to ozone-induced structural damage in the treatment chambers. Under the trial conditions, only the Kalanchoe would be able to tolerate the high levels of ozone required to kill the fungal spores.

Full textAbstract:
Protective border barriers were established at three sites in commercial floriculture, and strawberry fields in San Diego County, Calif. These border plantings were used to provide a physical barrier between agricultural fields and adjacent urban development, and to evaluate the effects of border plantings on insect populations, spray drift, and crop/barrier interactions. Border plantings consisted of native plants with overlapping flowering periods to provide nectar and pollen to beneficial insects throughout the year. Yellow sticky traps were used to monitor insect populations, and water sensitive paper was used to evaluate the reduction of spray drift by the border plantings. Results indicate that protective border plantings: 1) can be used to form attractive physical barriers that reduce visual pollution and spray drift; 2) provide habitat for pests as well as beneficial insects; 3) support beneficial insects that may help reduce the population peaks of pest insects during spring and summer months; and 4) have little effect on adjacent crop fields.

The article presents long-term data on the study of yield, biochemical parameters (tannin and extractive substances) and quality of tea raw materials (by the average mass of three-leaf fl ushes) of perspective mutant induced forms of tea breeding by Georgian scientists: 582 (radio mutant – aneuploid 2n = 36); 2264 (сolchicine mutant – mixoploid 2n = 38); 3823 (radio mutant – myxoploid 2n = 42). Standard Kolkhida variety was chosen as a control. The collection was planted in 1986 in CJSC «Dagomyschay» and is administered by the Russian Research Institute of Floriculture and Subtropical Crops. Vegetation of radio-mutant forms proceeded more actively, adaptability to summer drought was quite pronounced. By productivity, the following radiomutant forms can be distinguished: 582 (49.8 kg / ha) and 3823 (55.2 center/ha), with an excess over the control variety Kolkhida on 13.4-25.7 %. To a greater extent, the colchimutant form 2264 (30.2 C/ha) was inferior to the control, the credible diff erence was 31.2 %. In terms of the average weight of three-leaf fl ushes, the advantage was also in the mutant forms, it is 1.0 g and 0.96 g for the forms 3823 and 582, respectively, in the control variety the average weight was 0.89 g. It should be noting that the average mass of 3-leaf fl ushes was 0.4 g on the commercial plantations fi lled with local tea population. The biochemical parameters on tannin and extractive substances showed highest quality of fresh leaf yield of all mutant forms. At the same time, on this position, the mutant form 582 dominated, the tannin parameters exceeded the control variety Kolkhida by 2.6 %, the presence of extractive substances by 0.9 % (the infusion was moreintense). All the studying induced mutant tea forms represent practical interest for gene pool replenishment, breeding and implementation in commercial tea growing.

The 8th annual Southeast Greenhouse Conference and Trade Show (SGCTS) will be held in June 2000. This meeting is the result of cooperative efforts among the Alabama Nurserymen's Association, Florida Nurserymen and Growers Association, Georgia Commercial Flower Growers Association, North Carolina Commercial Flower Growers' Association, South Carolina Greenhouse Growers Association, Tennessee Flower Growers Association, Virginia Greenhouse Growers Association; and the Cooperative Extension Services and Land Grant Universities of all seven participating states, including Auburn Univ., Clemson Univ., the Univ. of Florida, the Univ. of Georgia, North Carolina State Univ., Univ. of Tennessee, Virginia Polytechnic Institute and State Univ., and Virginia State Univ. Through pooling of efforts and resources, the SGCTS has become one of the major floriculture educational and trade show events in North America, and it has grown from an initial participation of 347 and a trade show of 89 booths in 1993 to 2407 participants and 398 booths in 1999. The SGCTS serves as an excellent example of cooperative partnering among grower organizations, Cooperative Extension, and faculty at Land Grant Institutions. It eliminates duplication of efforts among individual states, each historically holding their own state meeting. Proceeds from the conference support grower organizations, which in turn support research and educational programs at the cooperating universities. Over $55,000 were disbursed back to the state associations in 1999.

Full textAbstract:
Most commercial and university substrate testing laboratories' recommended floriculture nutritional values are based on the saturated media extract (SME) method. With the recent gain in popularity of pour-through nutritional monitoring, alternative recommended values are needed for nutrient analyses based on pour-through extracts. Pour-through nutritional values were compared to the SME values to develop calibration curves and recommended nutritional values. Euphorbia pulcherrima `Freedom Red' Willd. ex Klotzch. were grown for two consecutive growing seasons in 16.5 cm plastic pots with Fafard 4 P root substrate and fertigated with 200, 300, or 400 mg·L-1 N from a 13N-0.88P-10.8K fertilizer. Linear relationships existed and inverse calibration curves for pour-through and SME comparisons were developed for (r2): EC (0.98), NO3- (0.98), P (0.97 to 0.99), K (0.99), Ca (0.94 to 0.97), and Mg (0.91). In addition, recommended pour-through substrate value ranges were developed for comparison with SME values. The established calibration curves and pour-through substrate value ranges will allow substrate-testing laboratories to make nutritional recommendations based on pour-through extractions.

The objective of this research was to determine the suitability of a steel slag product for supplying micronutrients to container-grown floriculture crops. Geranium (Pelargonium ×hortorum L.H. Bailey ‘Maverick Red’) and tomato (Solanum lycopersicon L. ‘Megabite’) were grown in 11.4-cm containers with a substrate composed of 85 peatmoss : 15 perlite (v/v). A group of containers referred to as the commercial control (C-control) were amended with 4.8 kg·m−3 dolomitic lime and fertilized with a commercial complete fertilizer providing macro and micronutrients (Jack’s 20N–4.4P–16.6K–0.15Mg–0.02B–0.01Cu–0.1Fe–0.05Mn–0.01Mo–0.05Zn) at a concentration of 100 mg·L−1 nitrogen (N). Another group of containers, referred to as the micronutrient control (M-control), were amended with a commercial granular micronutrient package at 0.9 kg·m−3 and dolomitic lime at 4.8 kg·m−3. The M-controls were fertilized with 7.1 mm N (100 mg·L−1 N) with ammonium nitrate and 2 mm potassium phosphate. A final group of containers were amended with 1.2, 2.4, or 4.8 kg·m−3 of steel slag and fertilized with 3.6 mm ammonium nitrate and 2 mm potassium phosphate. Both control groups resulted in vigorous and saleable plants by the conclusion of the experiment. In both crops, chlorophyll levels, root ratings, and shoot dry mass were lower in all steel slag–amended plants compared with either control groups. In geranium, foliar nutrient concentrations suggest Cu and Zn were limiting whereas B and Zn were limiting in tomato. Based on the results of this research, steel slag does not provide sufficient micronutrients, most notably B, Cu, and Zn, to be the sole source of micronutrient fertilization in container-grown crops.

<p>Rose is the principal flower of the world floriculture industry that is being exclusively used as cut flower, potted plant and garden plant. It plays significant part in numerous industries viz. food, perfumery and cosmetic industries. About 96 % of women’s perfumes contain true Bulgarian rose oil. Roses are well acclimatized in Jammu & Kashmir because of its suitable agro climatic conditions which can permit its large scale production and rose products produced in the state are at par with the international standards. But the aesthetic and commercial value of roses is greatly lowered by numerous insect pests resulting in low yield. However, its major pest include aphid species most notoriously Macrosiphum rosae that pose many challenges and threats to rose plant cultivation. Aphid colonies on roses result in reduction of medical value of the plant and cause economic losses to growers particularly during spring and summer season. In order to reduce the economic losses inflicted by rose aphid, it is necessary to study different biological parameters of this pest species so that an effective management plan can be formulated.</p>

Full textAbstract:
Prohexadione-Ca (ProCa) is a relatively new plant growth regulator (PGR) that inhibits internode length in rice, small grains, and fruit trees. However, little is known about its efficacy and potential phytotoxicity on floriculture crops and how it compares to other commercially available PGR chemicals. The effects of two foliar spray applications (2 weeks apart) of ProCa (500, 1000, or 2000 ppm), paclobutrazol (30 ppm), or a tank mix of daminozide plus chlormequat (2500 and 1000 ppm, respectively) were quantified on Dianthus barbatus L. `Interspecific Dynasty Red', Ageratina altissima R. King & H. Robinson (Eupatorium rugosum) `Chocolate', Lilium longiflorum Thunb. `Fangio', and Buddleia davidii Franch. `Mixed.' All plants were forced in a glass-glazed greenhouse with a constant temperature setpoint of 20 °C under a 16-h photoperiod. Two weeks after the second spray application of ProCa at 500, 1000, or 2000 ppm, plant height of Dianthus and Lilium was shorter than control plants by 56%, 60%, and 65% and by 6%, 26%, and 28%, respectively. However, ProCa bleached and reduced the size of Dianthus flowers. ProCa at 2000 ppm and daminozide plus chlormequat were effective at controlling the height of Eupatorium (64% and 53% reduction, respectively); however, leaves of Eupatorium were discolored and showed symptoms of phytotoxicity 1 week after the first ProCa application. Only daminozide plus chlormequat were effective on Buddleia. ProCa is an effective PGR for most of the crops we tested; however, its discoloration of red flowers and foliage may limit its application for commercial use.

In floriculture, more specifically in the segment of ornamental packaged plants, Adenium obesum has gained popularity. This is due to the important role it plays in the market of ornamental plants. Although its aesthetic standardization as a potted plant has not been defined yet, studies with focus on reducing its size are necessary. Thus, this paper aimed at evaluating the effects of different doses of the vegetal growth retardant paclobutrazol (PBZ) in Adenium obesum plant development and quality, in order to enable a differentiated product for the market of flowers and potted plants. The experiment was conducted in a vegetation house in randomized complete blocks with four repetitions. Six treatments were provided, that is, one single application of: 5; 10; 20; 40 and 80 mL of the active ingredient of PBZ, and the control treated with water only. For the biochemical evaluations, we verified the effect of treatments for the anthocyanin variable, with PBZ impairing the concentration of anthocyanin present in leaf tissues. The dose of 80 mL of PBZ reduced the length of aerial part in 37.29% in relation to the control. Despite the decrease observed in the plant final size, the phytotoxic effects caused by PBZ prevented its utilization in the Adenium obesum commercial production.

Cymbidium aloifolium (L.) Sw. is an epiphytic orchid distributed locally in Bangladesh. Natural populations of this orchid are under threat due to its high commercial value in the floriculture industry by over exploitation. Mass propagation provides an alternative means of satisfying the demand. In this study, half strength of MS supplemented with BAP or different combinations with NAA was evaluated for seed germination and early protocorm development of C. aloifolium (L.) Sw. The maximum percentage of seed germination (98) was obtained on modified MS (half strength of micro and macro nutrients and full strength of vitamin) supplemented with 0.5 mg/l BAP and 0.5 mg/l NAA after three weeks of culture. Maximum number of shoots (9.6 shoots per single shoot) were developed from shoot tip explants on half strength of MS supplemented with 1.0 mg/l BAP and 0.5 mg/l NAA. The most effective auxin source promoting root production (3.2 roots per shoot) was 1.0 mg/l IBA in combination with 0.5 mg/l BAP. The seedlings were successfully acclimatized (survival percentage 99) in a nethouse using a rooting medium of crushed sterile brick, cocopit and charcoal (1 : 1 : 1 v/v).

One of the many functions of sunflower (Helianthus annuus L.) is related to the use of its inflorescences in the flower market, which has guaranteed space for this species in floriculture in recent years. Sunflower has been highlighted as an ornamental plant for cutting. Studies have been performed aimed at reducing the size of this species, in order to improve its commercial production, which facilitates the production in field and in protected environments. The use of color shading nets can lead to growth manipulation and to the development of this species. The objective of this study was to evaluate the effect of full sun and the use of color shading nets Aluminet®, blue and red (Chromatinet®), on the development of ornamental sunflower cv. Pollenless Sunflower Sunbright. The studied variables were plant height, leaf number, diameter of the floral stem, inflorescence width and dry matter of leaves, stem and inflorescences. By the anatomical analysis of the leaves, it was possible to determine stomatal density, polar (DP) and equatorial (DE) diameters, as well as the relation DP/DE of adaxial and abaxial epidermis and leaf thickness. It is concluded that the best development of ornamental sunflower plants is observed in full sun and under Aluminet®.

Full textAbstract:
Impatiens (Impatiens walleriana) are currently among the most valuable and widely cultivated floriculture crops in the world. Attractive floral display is a primary goal for breeders of impatiens. Although breeders have selected for this trait, little consideration has been given to floral longevity as a means to increase the floral display of bedding crops. In this study, 259 commercial inbred lines of impatiens were grown in a greenhouse and evaluated for floral longevity as defined by the time between when a flower was completely open to when all of the petals abscised from the pedicle. Mean floral longevity of inbreds ranged from 3.3 ± 0.4 to 15.8 ± 2.5 days. Twelve inbreds (six with long floral longevity and six with short floral longevity) were chosen and crossed in a half diallel to create 66 hybrids that were analyzed for floral longevity in three greenhouse environments. Mean floral longevity of hybrids across greenhouse environments ranged from 2.8 ± 0.4 to 14.1 ± 2.8 days. Significant general (GCA) and specific (SCA) combining abilities for floral longevity were detected. GCA mean squares were 37 times larger than SCA mean squares, revealing that additive genetic effects play a more important role in the inheritance of floral longevity in impatiens. This information, coupled with the significant amount of variation for floral longevity among inbreds, indicates that there is good potential for breeding for floral longevity in impatiens to improve the floral display of hybrids.

Full textAbstract:
Many new vegetative annuals are available in the floriculture market today. Their growth habits may be trailing or vigorous and more conducive to hanging basket or container garden culture. Today's gardeners are living busy lives and housing is sometimes confined, with little land on which to garden. These factors all contribute to the popularity of hanging baskets and container gardens. Whereas container garden trials are more common in industry, few universities have added container gardens and hanging baskets to their trial gardens. The objective of the hanging basket and container garden trials at Univ. of Tennessee (UT) initiated in Summer 1999 was to demonstrate and promote this timely trend to commercial growers, landscapers, and the public. An attractive brick walkway and wooden arbor were built by a UT landscape construction class to display the containers and hanging baskets. Several challenges had to be met: funding the purchase of expensive containers; planting and placing the heavy containers in the garden; combining plants within the containers; grouping containers together; labeling plants within the containers; displaying the hanging baskets; maintenance and pruning; and most of all, keeping the containers watered throughout the summer. The color wheel proved to be a useful tool for grouping plants and containers. A handout was developed to guide visitors through the container garden. Despite the challenges, the container garden and hanging basket trials proved to be a successful demonstration and were popular among visitors.

Full textAbstract:
The gladiolus is an important cut flower that is cultivated in all parts of the world, and it is very appreciated to be used in floral arrangements. The growing concern with the environmental contamination and the look for production with higher quality have resulted in increasing the number of studies on the use of organic inputs and microorganisms in floriculture, in particular, the vermicompost and the Trichoderma sp. This work was conducted with the objective to evaluate the development and the quality of gladiolus floral stems in function of the use of vermicompost and Trichoderma sp. applied to the substrate. The experiment was conducted in a greenhouse during the period of August to December of 2015. It was done by utilizing four treatments: T1 = control substrate (50% soil and 50% commercial substrate Carolina Soil); T2 = vermicompost (40%) and control substrate (60%); T3 = Trichoderma sp. added to the control substrate; T4 = Trichoderma sp. added to the vermicompost (40%) and control substrate (60%). The gladiolus variety used was the Peter’s Pears. The variables analyzed were main plant height, Falker chlorophyll index, length and diameter of the main stem, tassel length, quantity of main stem florets, proportionality between tassel and stem, and time until the start of flowering. It was concluded that the development and the quality of the gladiolus floral stem were favored by the use of vermicompost in the concentration of 40% added to the substrate.

Full textAbstract:
The objective of the paper is to provide an overview of the situation and performance of Croatian farms. Croatian farmers rarely keep business books and therefore farm level business data are deficient. Croatian accession to the European Union in 2013 brought numerous innovations to agricultural sector. One is introduction of Farm Accountancy Data Network (FADN) which aims to determine the impact of the Common Agricultural Policy on national agriculture of EU member states. The sample of Croatian FADN comprises 1,250 commercial farms. The paper brings results of agricultural sector financial analysis for the period 2011-2013. Total farm output decreased, but since the stronger decrease trend occurred in total inputs, this led to positive trend of gross and net farm income in the year 2013. Positive results are also shown at efficiency and productivity of Croatian farms. In the years 2011 and 2012 farms operated below the efficiency level while in 2013 efficiency increased above the efficiency level. In the observed period there was a 70% increase in productivity. The analysis shows that the most efficient farms are those in vegetables and flowers type. It also has the highest debt ratio due to their capital intensiveness. The vegetable and floriculture farms have the largest gross farm income in all three analysed years, but with a large drop in 2013, while the farms in type pigs and poultry have largest increase of gross farm income in last observed year.

Lupinus albus ssp. graecus, L. Fabaceae (Boiss. and Spruner) Franco and P.Silva, is being studied at the TEI of Heraklion since 1998 as a new plant with potential use in floriculture and ornamental horticulture. The plant has been recorded botanically; however, little is known about its physiology and genetic profile. Lupinus albus ssp. is a herbaceous annual plant 10 to 20 cm tall, growing at roadsides, field margins, vineyards, and olive groves up to 700 m altitude. The leaves are 5 to 11 cm wide, palmate shaped in alternate orientation, with five to nine leaflets 10 to 18 mm wide, all arising from the same point. The flowers are borne in terminal or lateral spike-like racemes 10 to 20 cm long. Florets are 15 mm long, dark blue occasionally with a white patch, stamens forming a tube. Pods are 60 to 70 mm long,with four to six black-spotted seeds. In the present work, seed germination studies were conducted combining chilling pretreatments with physical scarification (scratching). Mature seeds chilled at 5 °C for 6 weeks germinated readily (83%) when scarified with sand paper. Furthermore, we tested the effects of several plant growth regulators (chlorocholine chloride, paclobutrazol, maleic hydrazide and Ethrel 48) on young plants of Lupinus in order to obtain compact pot plants with more flowering racemes. Paclobutrazol at 5 and 10 mg/L achieved the best retardation effect, but did not affect flowering. In another trial with different potting media,the commercial potting soil proved the most suitable for growing lupins satisfactorily. It is concluded that Lupinus albus spp. graecus L. need further investigation in order to establish the best cultural conditions for its growth and development. Furthermore, due to its high genetic variability, selection and genetic improvement is required for optimal results.

Chrysanthemum is one of the leading crops of commercial floriculture. Within garden groups and classes, chrysanthemums are divided according to cultivation methods, shape and size of the inflorescences. For varieties grown on a cut, a group of large-flowered (with a diameter of inflorescences of 12-25 cm), small-flowered (4-10 cm) chrysanthemums and santini (from 2 to 4 cm) is distinguished. Having a limited assortment of chrysanthemum garden, in a humid subtropical climate, it is possible to form a largeflowered (single-headed, disbud) and small-flowered (spray) cut. The purpose of the research was to study the peculiarities of formation of large-flowered chrysanthemums (Chrysanthemum×hortorum Bailey) to obtain cut in the humid subtropics of Russia. The objects of research were large-flowered and small-flowered varieties of chrysanthemums of foreign and domestic breeding. The studies were carried out in the open ground of the Department of Agricultural Engineering and Nursery of the Federal Research Center the Subtropical Scientific Center of the Russian Academy of Sciences. Scientific research was carried out according to the methodology of State variety testing of agricultural crops and the methodology of testing for distinctness, uniformity and stability of chrysanthemum (perennial) Chrysanthemum spec. ‘Sevan’, ‘Baltica White’, ‘Granada’ and ‘Zembla Brasil’ are large-flowered varieties, which have bush peduncles of good commercial quality with large inflorescences of saturated shades. In turn, from small-flowered garden forms ‘Zembla White’, ‘Annecy White’ and ‘Westland Regal’ with regular pinching, you can grow a large-flowered cut of chrysanthemums. It was revealed the relationship between biometric characteristics in order to determine additional diagnostic features of the possibility of the formation of large-flowered inflorescences. So, the diameter of the inflorescence is the most significant parameter for research which has significant positive relationships with the diameter of the peduncle and the length of the extreme ray flower. It will allow determining the possibility of growing the variety in one form or another, depending on the needs of production, at the initial stages of introduction and variety study.

Full textAbstract:
The plant family Amaryllidaceae is known for its horticultural and ornamental appeal as well as its medicinal value. In relation to these characteristics, trade in Amaryllid flower varieties (especially daffodils) is a multi-million dollar revenue generator for the floriculture industry. Of greater significance are the medicinal attributes of the family, which has already spawned the Alzheimer's prescription drug galanthamine, a potent and selective inhibitor of the enzyme acetylcholinesterase, of significance in the progression of neurodegeneration associated with motor neuron diseases, with annual global sales of around $150 million. Furthermore, it is anticipated that an anticancer drug target related to the Amaryllidaceae alkaloid pancratistatin, presently under advanced clinical evaluation, will enter commercial circulation within the next decade. Members of the Amaryllidaceae are distributed through both tropical and subtropical regions of the globe, but are of prominence within three distinct geographical locations, including Andean South America, the Mediterranean basin, and southern Africa. The southern African zone is known to harbor at least a third of the worldwide complement of around 1000 species, many of which are widely utilized in the traditional medicinal practices of the indigenous people of the region. Given its therapeutic and economic value, its natural abundance in the southern African region, coupled to its widespread usage in ethnic medicine, the family Amaryllidaceae provides a diverse and accessible platform for phytochemical based drug discovery. A consolidation of its traditional usage as well as its chemical and pharmacological profiles will thus guide efforts aimed at maximizing this potential. In undertaking this survey of the Amaryllidaceae of southern African, we aimed to achieve these goals.

Full textAbstract:
Potted poinsettia (Euphorbia pulcherrima) is an important commercial commodity for the U.S. floriculture industry. The production of poinsettia demands intensively managed light control, heat, fertilizer, and water; inhibiting elongation with plant growth regulators, and protecting plants from diseases and pests with pesticide applications. Excessive irrigation creates pollution, promotes disease, and is expensive. Sensor-based control systems can optimize irrigation schedules. Irrigation management is crucial in nursery production of poinsettias because water is a limited resource and agricultural runoff is monitored in many states across the United States. By pairing environmental sensors with sensors that continuously monitor plant transpiration, we can determine how plant water use and water stress fluctuate with environmental and physiological demands. We hypothesized that continual measurements of sap flow could be correlated with environmental sensors to develop a new water stress index (WSI), which can deliver the benefits of detecting water stress that might affect the quality of potted poinsettias. To test this hypothesis, rooted cuttings of poinsettia (E. pulcherrima cv. Prestige Red) were individually potted into twelve 11-L black plastic nursery pots. Potted plants were grown in a naturally illuminated temperature-controlled glasshouse. The 12 plants were randomly assigned one of three watering treatments: weekly, biweekly, and triweekly irrigation. From the data collected, we were able to create a WSI that correlated available soil moisture with the difference between the expected transpiration with actual transpiration rates. Our results suggest that the plants in the weekly treatment group did not experience water stress until 0.3 m3·m–3 volume water content indicated by <0.2 WSI. These results support previous research that found 0.1 to 0.3 m3·m–3 can be stressful soil moisture conditions for greenhouse-grown crops. Results also show that for substrates with similar substrates that irrigation set points can be reduced to 0.2 m3·m–3 for improved irrigation efficiency.

A case study is presented for use as an active learning tool for students in a floriculture potted plant production class. This is the second case study developed for Floratech, a potted plant finisher. Students work together in small groups to solve the proposed problems; each student role-plays as a Potted Plant Production Specialist. A memorandum from the Board of Directors is delivered in their first month on the job at Floratech. Objectives of this case study are to determine the students' fluency in terminology and crop-specific cultural requirements for potted plant production of cyclamen (Cyclamen persicum) and primrose (Primula sp.) as well as their ability to setup a scientifically rigorous and unbiased cultivar trial for Floratech personnel and selected customers. Students research the latest commercial catalogs to determine which species, series, and cultivars are available, as well as their relative merits, prior to choosing the appropriate cultivars to include in the trial. The trial setup has a space limitation of 2,000 ft2 (186 m2). This case study was tested with 20 undergraduate students during Fall Semester 1999. The case study demonstrated the students' fluency with terminology and crop-specific cultural requirements for both crops. Their ability to set up a scientifically rigorous trial varied widely, often with an inadequate sampling of cultivars and excessive replications (56 ± 37 cyclamen to 132 ± 65 primrose). A mean ± sd of 4 ± 1 cyclamen and 7 ± 3 primrose series were chosen. The number of cultivars varied from 6 ± 2 cyclamen to 9 ± 4 primrose and the number of distributors was similar for the crops. Trial design and additional questions raised by the case study were discussed in class and applied in a cultivar trial in the lab. Unanswered questions were used as learning opportunities during class tours with local growers.
