Abstract:
The work presents the evaluation results of the viability of oat and barley collection varieties during storage in the laboratory conditions at the temperature of 20-25o C. Seed storage covered the period of 2006-2017. The research included 24 varieties of barley and 29 varieties of chaffy oats of domestic and foreign breeding collection. The seeds were stored in different packaging materials such as standard paper package; glass bottles of 0.25 liter and plastic bottles of 0.5 liter. The initial seed moisture content was 8.5-9.0 per cent. The varieties were divided into groups taking into account the initial laboratory seed germinating ability. For oats the fi rst group included 10 varieties with initial germination of 96-99%; the second group included 12 varieties with initial germination of 91-95%; the third group included 7 varieties with initial germination of 86-90%. For barley the fi rst group consisted of 5 varieties with initial germination of 91-99%; the second group consisted of 10 varieties with initial germination of 81-90%; the third group consisted of 9 varieties with initial germination of 71-80%. Determination of seed quality was carried out in 7 and 11 years’ time. The initial moisture content of seeds remained without signifi cant changes in all packaging types during the storage period of 11 years. It was also noted that germination of oat and barley seeds during 7 years of storage did not differ in any type of package. The average value in all three groups of oats was 93.2%. After 11 years of storage, germination of oat differed a little, depending on the type of package. In a paper bag it was 80.4%; in a glass bottle – 88.2%; in a plastic bottle – 85.1%. The average initial germination of three groups of barley in 7 years’ time of storage was 84.7%. After 11 years of storage, germination of barley was 53.2% in a paper bag; 63.3% in a glass bottle; 61.8% in a plastic bottle It was revealed that oat and barley seed germination in 7 years’ time did not differ in any type of package. After 11 years, germination of oats was 5.8% higher, and germination of barley was 8.6% higher in a sealed plastic bottle than in a standard paper bag. Differences in seed germinating ability between the glass and plastic bottles were not observed.

Abstract:
Endemic populations of Hechtia perotensis have been described in Puebla and Veracruz, Mexico. Good quality seed collections can be used in conservation, research and ecological restoration. To evaluate seed quality of wild and endemic species, some compounds are used as effective promoters of germination, such as potassium nitrate (KNO3) and gibberellic acid (AG3), because they increase seed germination capacity and reduce latency. The triphenyl tetrazolium chloride (tetrazolium) test correlates seed viability because it is based on the activity of dehydrogenases in live tissues that catalyze mitochondrial respiration. The objective of this study was to obtain information on size and weight of capsules and seeds and seed germination and viability of H. perotensis, collected in Veracruz in the year 2012 and 2015. The hypotheses were 1) that seed germination and viability are independent of the year of collection, 2) that there is a tetrazolium concentration that can identify seed viability better than others, and 3) that pretreatment with KNO3 or AG3 improves seed germination. Seed germination was assessed using a completely randomized design with three treatments (control and the germination promoters 0.2 % KNO3 and 500 mg/L AG3), four treatments for the viability test (control, 0.2, 0.5 and 1.0 % of tetrazolium) and six replicates for each treatment. A total of one hundred seeds for germination experiments, and 25 seeds for the viability test were used. The results between and within years were analyzed with ANOVA and multiple comparison with the Tukey test. The proportion of non-germinated seeds was quantified along with the number of normal and abnormal seedlings, seeds with viable embryo, seeds without embryo, and seeds with low or no viability. On average, for the 2012 collected sample, 36 % had viable embryos, 7 % had low viability, 24 % were not viable and 33 % had no embryo. This result was significantly different from the 2015 sample, for which 87 % of seed showed viable embryos, 10 % had low viability, 0 % was not viable and 3 % had no embryo. Seed germination was also significantly different between years (22 and 92 %) Pregerminative treatments did not improve germination. Seed germination and viability of H. perotensis significantly varied between years of seed collection.

Abstract:
The suitable seed storage method is important to maintain seed viability. This study aimed to examine the effect of periods and media storage on the viability of cananga seed (Cananga odorata (Lam.) Hook.f. & Thomson forma genuina). The treatments used in the seed viability test were 0, 2, 4, and 6 weeks as period storage and cocopeat, ash, and charcoal as media storage. The seeds were stored in the plastic at room temperature (± 25°C). The variables observed in this study were seed moisture content, percentage of germination, maximum growth potential, average days of germination, T50, germination value, and the number of seeds that germinate during storage. The percentage of C. odorata seeds germination without storage is 54%. The seed storage for 2 – 6 weeks in ash and charcoal hush caused their viability was drop. The seeds storage of C. odorata up to 6 weeks in cocopeat could maintain seeds viability with a percentage of germination that has no significant difference compared to control. In general, cocopeat can be used as one of the storage media in the seed storage of C. odorata before sowing.Keywords: Cananga odorata, cocopeat, germination percentage, seed, viability

Abstract:
Viability and vigor are components of seed quality assessment which are influenced by internal and external factors of the seed, i.e., salinity and temperature. Salinity is related to the interaction between osmotic pressure and seed germination. This study used 3 types of seeds, they are peanuts (Arachis hypogaea L.), mung bean (Vigna radiata (L.) R. Wilczek), and corn (Zea mays L.). The purposes of this study were to determine seed viability by using Triphenyl tetrazolium chloride (TTC), to analyze the effects of different osmotic pressures and temperatures on seed viability and vigor. Peanut seed viability test was conducted by using 1% TTC solution. Testing the effect of osmotic pressure on seed viability and vigor was conducted by using various concentrations of NaCl (0.01 M; 0.05 M; 0.5 M; 0.1 M; 1 M). The germination test of the three seeds was conducted by using temperatures of 30°C and 35°C, each with three replications. The test parameters measured included germination, germination rate, germination speed index, vigor index, simultaneous growth, and the speed of seed growth. The results showed that TTC solution was effectively used to determine seed viability. Mung bean had the highest germination rate, LP, IKP, IV, simultaneous growth, and speed of seed growth compared to the other tested seeds in all salinity and temperature treatments. The 30 ⁰C temperature treatment resulted in the best viability and seed vigor for the three tested plants. Treatments of temperature and salinity affect the quality of the three plant seeds which can then be used to determine the quality of peanut, mung bean, and corn seeds.

Abstract:
Background: A high proportion of Asteraceae species are considered weeds, some of them have recognizable biological properties. To design production protocols and ex situ seed conservation programs is necessary to determine the effect of storage temperature on seed viability and longevity. It is known that cold temperatures maintain seed viability and thus prolong seed longevity. Hypotheses: The seeds of Aldama dentata, Verbesina virgata, Stevia origanoides and Roldana barba-johannis stored at low temperature (5 ºC) will have greater longevity than when stored at room temperature (16.45 ± 1.94 oC) and will decrease their viability as they age. Study site and dates: Seeds of the four Asteraceae were collected (November-December 2015) in The National Park “El Tepozteco”, Morelos, Mexico and in the “Chamilpa” campus of the Universidad Autónoma del Estado de Morelos. Methods: The monthly germination experiments (11) were implemented with seeds stored under both temperatures, germination (%) and mean germination time were registered to estimate seed longevity. The seed viability stored at room temperature was evaluated with the tetrazolium test. Results: Germination and viability decreased with seed age. Along the experiment, seed germination was similar at both storage temperatures. A. dentata and S. origanoides showed the highest germination but A. dentata alone reached the major seed viability. The oldest seeds germinated faster. Conclusions: Seed longevity of all the species exceeded one year. For propagation purposes, it is recommended to use seeds between 8 and 9 months of age, when their germination and viability are the highest.

Abstract:
Seed viability is one of the most important physiological quality benchmarks of seeds. The use of appropriate germination media can affect the results of seed viability testing. This study aims to determine the optimal germination media in tobacco seed viability testing. This research was conducted at the Seed Laboratory of the Indonesian Sweetener and Fiber Crops Research Institute, Malang in January - March 2019. The research method used a two-factorial randomized block design (RAK). The first factor is tobacco seed varieties consisting of Kasturi in 2007, Bojonegoro in 2012 and Kemloko in 2014. The second factor is the seed germination media consisting of straw paper, cotton, towel tissue, paperboard and newspaper. The results showed that the Kemloko variety of tobacco seeds germinated in the towel tissue had the best seed vigor and viability percentage. Seed germination media with paperboard, towel tissue and straw paper can be used to test the viability of tobacco seeds because they have a percentage of simultaneous growth, percentage of the growth speed, percentage of germination, percentage of the growth potential maximum and normal seedling dry weight which are equally well

Abstract:
Vermicompost or worm-worked wastes have been reported to enhance seedling germination and growth during plug production. The objective of this project was to examine the effects of vermicompost on germination of a herbaceous perennial having varying viability in coir-based container media. Seeds of Echinacea purpurea (Purple Coneflower) collected from field-grown plants in 1998 and 1999 were considered low- and medium-viability seeds, respectively. A third group of seeds was purchased from a major seed company and was considered to have high viability due to optimal storage conditions. “Ragdoll” germination tests resulted in the following viability ratings: low (1%), 1998; medium (67%), 1999; and high (79%), purchased seed. The three sources of seed were planted into coir-based media. Vermicompost was incorporated into the media at 10% by volume. The control media did not have vermicompost added. Twelve days after project initiation seeds sown into media containing vermicompost had 73% and 90% greater germination than control media for the 1999 and purchased seed. At the project conclusion, 24 days after initiation, seeds sown into media containing vermicompost had 23% and 42% greater germination than the controls for the 1999 and purchased seed. The 1998 seed had 5% germination after 24 days compared to 1% for the control. The addition of vermicompost could be used as a method to increase germination rate and percentage of seeds having lower viability.

Abstract:
The caper (Capparis spinosa L.) is a perennial plant characteristic of the Mediterranean region that presents difficulties in its propagation, both vegetatively and by seeds. The main aim of this study is to provide collection guidelines to achieve a viable caper commercial propagation, for which three experiments were undertaken to determine the viability and germination in different seed lots. In the first experiment, commercial and own produced seeds (collected with the same criteria as commercial seeds) were analysed; the commercial seeds presented the lowest viability and germination. The second experiment analysed the effect of the fruit (from which the seeds were extracted) at its maturation stage, obtaining the lowest seed viability and germination in the seeds extracted from the dry fruits. In the third experiment, seed viability and germination were analysed immediately after collection, following a short drying period (3 d), and after six storage months. Viability and germination decreased with seed storage. Overall, it can be stated that caper seeds are sensitive to desiccation; consequently, a general rule of thumb is to collect the fruits once a week, to extract the seeds, and to plant them immediately for germination.

Abstract:
The article presents the study of influences of cryopreservation on seed germination of Matricaria chamomilla. Four varieties «Moscow Region», «Karagandinskaya», «Aibolit» and «Old Lekar» are used in the work. The seeds of the test species are cryopreserved in liquid nitrogen, followed by defrosting at room temperature and rapid defrosting in a water bath at temperature +40 Ԩ. After cryopreservation the seeds are planted in Petri dishes and placed in a climate chamber for determination laboratory germination. It is noted that the best results are obtained in the defrosting variant at the room temperature. So the maximum germination rate for variety «Karagandinskaya» was 84.0 %, energy of germination — 83.0 %; for «Aibolit» variety was 82.0 % and 81.0 %, respectively; «Moscow Region» variety had a minimum germination rate — 13.0 % and energy of germination 10.0 %. While for the «Old Lekar» variety, the optimal thawing mode was rapid thawing in a water bath at the temperature +40Ԩ; seed germination was 63.0 %, energy of germination — 62.0 %. Thus, it is necessary for receiving more viable seeds of varieties of Matricaria chamomilla after freezing in liquid nitrogen to apply the slow mode of thawing at the room temperature +24 Ԩ.

Abstract:
The conditions which prolong viability and the low germination rate of seeds of Afrocarpus gracilior were studied. Different seed lots were stored under various moisture content and temperature combinations. The two seed lots tested had different initial viabilities, probably due to different pre-storage treatments, but generally similar storage requirements to maintain viability at a reasonable level. Tetrazolium tests gave consistently higher viability estimates than germination tests but were well correlated with the latter. Intact seeds were found to have a very low germination rate. However, removal of the seed coat and germination at 30oC resulted in germination rates of up to 80% after 30 days. The seed coat was found to contain a very powerful inhibitor of germination of Triticum seed. Studies were made on the germination of seeds of Ekebergia capensis and Pygeum africanum. Intact seeds of E. capensis germinated at about 52% under optimum conditions and slight damaging of the seed coat halved the germination rate. Intact seeds of P. africanum germinated at about 20% under optimum conditions and slight damaging of the seed coat doubled the germination rate. Shoots of A. gracilior were found to grow well in vitro on hormone free medium but did not produce axillary buds during normal growth and development. However, it was found that decapitation resulted in the formation of axillary buds at or near the top of the shoots which subsequently developed into shoots. Treatment of intact or decapitated shoots with benzyladenine resulted in the initiation of numerous buds but it proved impossible to extend them into shoots. Extending shoots rooted spontaneously on hormone free medium and were also rooted ex vitro in compost under non-sterile conditions and the rooted plants were weaned to greenhouse conditions.

Abstract:
This study investigated primary seed dispersal of !nara (Acanthosicyos horridus) by Blackbacked Jackals (Canis mesomelas) and secondary seed dispersal by scatter-hoarding hairyfooted gerbils (Gerbilliscus (Gerbillurus) spp.) in the central Namib Desert. This was accomplished by examining visitation rates and fruit removal of !nara melons, primarily by jackals. In addition, I determined the viability and germination rate of !nara seeds collected from jackal scat. The results indicate that jackals were the dominant species to visit !nara (93.3%) and the only !nara frugivores recorded by camera traps over two !nara fruiting seasons. There was no difference in the viability of ingested seeds and control seeds, but germination rates of ingested !nara seeds were significantly higher (50.4%) than control !nara seeds (34%). This component of the study suggests that Black-backed Jackals are the main primary dispersers of !nara seeds in the central Namib Desert. I furthermore examined secondary seed dispersal by tracking !nara seeds to determine whether scatter-hoarding hairyfooted gerbils were caching or consuming seeds. I recorded the distance moved, depth of seed burial, recovery rate and the habitats in which seeds were buried in three habitat types. Hairyfooted gerbils removed 100% !nara seeds from experimental sites and cached 60.3 % of all the !nara seeds removed. The gerbils frequently retrieved the buried caches within two days (77% of the time) and re-cached them elsewhere. The majority of caches were in the open areas (83%) and only consisted of one (39%) or two seeds (45%). Only 1.7% of the cached seeds were not retrieved by the gerbils during the 30-day observation periods. !Nara seeds were moved an average distance of 29.1±1.6 m and buried at an average depth of 4±0.2 cm. Although there is high probability of cache retrieval, some of the cached seeds survived. As gerbil caches are at favourable locations for plant establishment, and as it is more likely that buried seeds will survive until suitable conditions for germination and seedling establishment, seed dispersal by hairy-footed gerbils is advantageous to !nara plants. Therefore, hairy-footed gerbil species in the central Namib Desert contributed to secondary seed dispersal of !nara. The combined interaction of endozoochory by Black-backed Jackals (Canis mesomelas) and synzoochory by hairy-footed gerbils (Gerbillurus spp.) in dispersing seeds of !nara plants (Acanthosicyos horridus) in the central Namib Desert suggest diplochory is highly likely.

Abstract:
Germination and establishment was evaluated in Arizona cottontop (Digitaria californica (Benth.) Chase), bush muhly (Muhlenbergia porteri Scribn.) and plains lovegrass (Eragrostis intermedia Hitchc.) from southern Arizona. Germination was determined in different aged seed harvested from native and irrigated plots of various populations. Results indicated variability in germination characteristics of study species that appeared unrelated to afterripening or dormancy. Germination ranged from 62 to 96% for Arizona cottontop, 34 to 99% for plains lovegrass, and 75 to 99% for bush muhly. Bush muhly had highest average velocity of germination (58.0 ± 4.1), followed by plains lovegrass (35.9 ± 1.91), and Arizona cottontop (31.4 ± 1.13). Effects of 3 surface treatments (furrows, gravel, litter) and 2 cultivation treatments on establishment of study species and yellow bluestem (Bothriochloa ischaemum (L.) Keng var. ischaemum) was investigated in the field. Bush muhly did not emerge and plains lovegrass had minimal emergence. Arizona cottontop had similar emergence in cultivated and uncultivated plots whereas yellow bluestem had greater emergence in cultivated plots. Litter promoted greater survival of Arizona cottontop. Lower survival in furrows may have resulted from fewer days with available soil moisture and interference from greater density of non-seeded species. Soil covers appear to positively influence survival rather than emergence. Effect of rainfall distribution on germination was investigated using 2 seed retrieval methods. Arizona cottontop and bush muhly germinated after at least 3 days of available soil moisture. Plains lovegrass seeds did not germinate in the field but retrieved seeds had 83% germination, possibly due to light exposure under laboratory conditions. Another study determined whether species have different density and cover under overstory species compared to open areas. Arizona cottontop had either greater, less, or no differences in density under canopied versus open areas. Cover of Arizona cottontop was greater or similar among canopied and open areas. Plains lovegrass had lower or similar density and cover under canopies than in open areas. Bush muhly had greater density and cover under canopies. Overall, studies suggested that species are easily germinated, but accept relatively narrow ranges of environmental conditions for establishment. Establishment may be enhanced by sowing species when rainfall is consistent, extending available moisture through use of soil covers, or mimicking microsites where a species occurs naturally.

The growing awareness of society to ecological problems is providing a considerable increase in demand for seeds and seedlings of native species. The Balfourodendron riedelianum (Engler) Engler is a native woody species of economic importance and ecological landscape, popularly known as ivory wood. The purpose of this study was to identify the ideal temperature for germination and determine the seed physiological potential of this species collected from different sources. The objective also their behavior with respect to storage and predict the storage period seeds and determine the constants of the longevity equation. Seeds collected in Marechal Cândido Rondon, Entre Rios do Oeste and Diamonte D'Oeste / PR were studied. For germination evaluation, two temperatures, 25 oC and 20-30 oC constant alternating with a photoperiod of 16-8 hours, and as substrate germitest paper were used. It was stored for 360 days, fruit in two different packaging (bag Kraft paper and glass) and in two different environments (controlled and uncontrolled). The experimental design used was completely randomized. The evaluated variables were: fruit length, percentage of germination, first count of germination, germination velocity index, moisture content, weight of thousand fruit and seedling length. Storage periods were 0, 90, 180, 270 and 360 days after fruit processing. For the development of the equations of longevity it was determined constants that made the equation through regression lines. The germination seeds of Balfourodendron riedelianum (Engler) Engler, was not affected by constant temperature of 25 oC compared with temperatures of 20-30 oC. The seedling length ivory wood was not influenced by temperatures of 25 oC constant and alternating temperature of 20-30 oC, from 90 days of storage. Among provenances, Entre Rios do Oeste stood out from the others to 0 and 360 days when he presented the highest rate of germination. The fruit stored in glass containers in uncontrolled environment and environmental conditions, did not show variations, related to the water content, thus demonstrating the best way to store ivory wood fruit. The mass of a thousand fruits stick ivory were 329.5 g, 585.5 g and 450.0 g for the provenances of Marechal Cândido Rondon, Entre Rios do Oeste and Diamonte D'Oeste, respectively. To seed ivory wood, the constants found to predict longevity were: Ke = 2.8667; Cw = 9.7697 E-013; Ch = 1.3435 E-012 and Cq = 1.1651 E-013. Using the storage conditions with average temperatures of 23 oC or 15 oC, and the ivory wood seeds showing moisture content of 12%, can be stored for up to 2 years. The values of the Pearson correlation between the actual percent germination calculated and the percentage of germination were 73% and 76% for the provenances Entre Rios do Oeste and Diamonte D'Oeste, and 77% and 74% for uncontrolled and controlled environment, respectively
A crescente conscientização da sociedade para os problemas ecológicos vem proporcionando um considerável aumento na demanda por sementes e mudas de espécies nativas. O Balfourodendron riedelianum (Engler) Engler é uma espécie lenhosa nativa, de importância econômica, paisagística e ecológica, popularmente conhecida como pau marfim. Objetivou-se, neste estudo, identificar a temperatura ideal para germinação e determinar o potencial fisiológico de sementes desta espécie, colhidas de diferentes procedências. Objetivou-se também verificar o comportamento das sementes com relação ao armazenamento, predizer o período de armazenamento destas sementes e determinar as constantes da equação de longevidade. Foram estudadas sementes, colhidas em Marechal Cândido Rondon, Entre Rios do Oeste e Diamante D Oeste/PR. Para avaliação da germinação, foram utilizadas duas temperaturas, 25 oC constante e 20-30 oC alternada, com fotoperíodo de 16-8 horas, e como substrato o papel tipo germitest. Armazenou-se, por 360 dias, os frutos em duas diferentes embalagens (saco de papel Kraft e vidro) e em dois diferentes ambientes (controlado e não controlado). O delineamento, utilizado, foi inteiramente casualizado Foram avaliadas as variáveis: comprimento de frutos, massa de mil frutos, porcentagem de germinação, primeira contagem de germinação, índice de velocidade de germinação, grau de umidade e comprimento de plântulas. Os períodos de armazenagem foram: 0, 90, 180, 270 e 360 dias após o beneficiamento dos frutos. Para a elaboração das equações de longevidade determinou-se as constantes que compõem a equação através de curvas de regressão. A germinação das sementes de Balfourodendron riedelianum (Engler) Engler, não sofreu efeito da temperatura constante de 25 oC, quando comparadas com temperaturas alternadas de 20-30 oC. O comprimento das plântulas de pau marfim, não foi influenciado pelas temperaturas de 25 oC constante e temperatura alternada de 20-30 oC, a partir de 90 dias de armazenamento. Entre as procedências, a Entre Rios do Oeste destacou-se das demais aos 0 e 360 dias, quando apresentou os maiores valores de velocidade de germinação. Os frutos, armazenados em embalagens de vidro e em local sem controle das condições ambientais, não apresentaram variações relacionadas ao teor de água, evidenciando, assim, a melhor maneira de armazenar frutos de pau marfim. Os valores da massa de mil frutos de pau marfim foram 329,5 g, 585,5 g e 450,0 g para as procedências Marechal Cândido Rondon, Entre Rios do Oeste e Diamante D Oeste, respectivamente. Para sementes de pau marfim, as constantes encontradas a fim de predizer a longevidade foram: Ke= 2,8667; Cw=9,7697E-013; Ch=1,3435E-012 e Cq=1,1651E-013. Para as condições de armazenamento com temperaturas médias de 23 oC ou de 15 oC, e as sementes de pau marfim apresentando grau de umidade médio de 12%, podem ser armazenadas pelo período de até 2 anos. Os valores da Correlação de Pearson entre a porcentagem de germinação real e a porcentagem de germinação calculada foram 73% e 76%, para as procedências Entre Rios do Oeste e Diamante D Oeste, e 77% e 74%, para ambiente não controlado e ambiente controlado, respectivamente

Abstract:
AbstractThe growing demands for improved seeds of food, vegetables, flowers, other horticultural species, feed, fibre, forage, and fuel crops are driving the global seed industry at a CAGR of 6.6%, which is expected to grow from a market size of USD 63 billion in 2021 to USD 86.8 billion by 2026. This will primarily depend on two key features, genetic enhancement of the crop variety and seed quality. The focus of varietal improvement will be not only on yield increase but also on tolerance against biotic and abiotic stresses to meet the challenges of climate change, better input use efficiency, and improvement of the nutritional value. Advanced molecular tools and techniques including gene editing are likely to be used for precision breeding. The scope of seed quality, on the other hand, will grow beyond the basic parameters of purity, germination, and health, to the ability to perform better under adverse growing conditions, supplement the nutrient deficiency in the soil, and withstand pests during seed germination and early growth stages. Seed enhancement technologies will complement the genetic enhancement, as the advancements in seed technology will become an integral part of future crop improvement programmes. This will call for more efficient and precise technologies for determining quality parameters and predicting seed longevity, which will need to be developed using advanced marker technologies, 3D and multispectral imaging analysis, digital phenotyping, and other non-destructive methods. Novel approaches of hybrid seed production, including apomixis and doubled haploidy, will be integrated further for their commercial application. Multi-dimensional approaches need to be taken for addressing the gaps in understanding the key physiological processes underlying the regulation of dormancy (and pre-harvest sprouting), germination, recalcitrance, loss of viability, and seed priming.

Abstract:
The Eastern pasqueflower (Pulsatilla patens (L.) Mill.) is considered as an endangered species in all European countries where it is found, including Latvia. An important factor for the survival of P. patens - a species with low competitiveness is not only the conditions suitable for germination and further growth, but also the indicators of seed viability. This is particularly important as there is no persistent soil seed bank for this species. Only limited data is available on the factors affecting seed viability, especially in the terms of soil conditions. Therefore, the main goal of this study was to find out the potential relationship between seed viability and soil agrochemical composition in 8 different locations of P. patens in Latvia. Demographic parameters were also analyzed as factors that could lead to differences in seed viability between populations. Overall, there were almost no substantial differences between study sites in terms of the seed production per one infructescence of P. patens. However, significant differences were found in seed viability data, with the percentage of viable seeds ranging from 2.1% to 53.8%. The results revealed a significant positive correlation between seed viability and concentrations of Ca and Mg in the soil. Our study suggested that one of the factors that positively affect seed viability could be the higher micronutrient (B, Cu, Fe) level in the topsoil. In addition to the wide range of nutrient concentrations in the soil, the studied sites also differed according to the demographic characteristics of the populations. Preliminary results showed that populations with a higher proportion of new generative plants had higher levels of viable seeds. This was convincingly evident in the nearby sample plots. Comparing the two adjacent areas, it was found that new generative plants dominated in those where the values of at least two soil parameters, such as Ca, Mg, organic matter, Cu and Fe, were higher. Further research is needed to better understand the relationship between soil conditions, population demographics and seed viability, thus contributing to the development of protection measures for P. patens in Latvia.

Abstract:
Lentil is one of the important pulse crops in the world with a high proportion of easily digestible protein. However, there are several pests and pathogens which cause losses during crop growth, harvesting and post-harvest storage. Microwave processing has shown great potential to eradicate pests and pathogens from grains; however, there is still concerns about its heat uniformity, which is of crucial importance in pest and pathogen control. Fluidization using forced hot air is one of the potential solutions for having uniform temperature during microwave processing. In this study, a single mode microwave cavity, with a 2.45 GHz microwave source, was modified to have a microwave fluidized bed and used to evaluate its potential to eliminate the Botrytis grey mold (BGM) pathogen, which is one of the important seed-borne pathogens of lentil crops in Australia. Air speed was maintained to be constant during the experiment and was just enough to fluidize 100g of red lentils in the sample holder. Two wet based (w.b.) seed moisture contents (m.c.) of 10.5% and 18.5% were prepared and the process parameters were selected as: air temperature at 50 and 60°C; microwave power at 0, 300, 400 W for 18.5% m.c. and 0, 400, 500 W for 10.5% m.c.; and exposure times of 5 and 10 min. These parameters were chosen to reach the final temperature of below 70°C. The effect of process parameters on seed moisture loss, seed germination, electrical conductivity of seed soaking water and percentage of infected seeds (IS%) were analyzed using general factorial regression and analysis of variance. The results showed that the most effective factors on moisture loss, after seed moisture content, was exposure time, followed by microwave power and air temperature. While final bed temperature was affected mostly by air temperature, and then by microwave power. Furthermore, based on general full factorial regression and pareto chart of standardized effects, moisture content had by far the most influence on the reduction of IS%. Seed pathogen inoculum reduction, without significant seed viability loss, was obtained by applying microwave power of 300W and set air temperature of 60°C (actual inlet air temperature of 57±1°C) on seeds with m.c. of 18.5% for 10 min. This gave a 27% reduction in IS% (from 82% to 55%).

Full text
Abstract:
Freshwaters can experience growths of toxin-producing cyanobacteria or harmful algal blooms (HABs). HAB-producing cyanobacteria can develop akinetes, which are thick-enveloped quiescent cells akin to seeds in vascular plants or quiescent colonies that overwinter in sediment. Overwintering cells produce viable “seed beds” for HAB resurgences and preventative treatments may diminish HAB intensity. The purpose of this literature review was to identify (1) environmental factors triggering germination and growth of overwintering cells, (2) sampling, identification, and enumeration methods, and (3) feasibility of preventative algaecide treatments. Conditions triggering akinete germination (light ≥0.5 μmol m-2s-1, temperature 22-27℃) differ from conditions triggering overwintering Microcystis growth (temperature 15-30℃, nutrients, mixing). Corers or dredges are used to collect surficial (0-2 cm) sediment layers containing overwintering cells. Identification and enumeration via microscopy are aided by dilution, sieving, or density separation of sediment. Grow-out studies simulate environmental conditions triggering cell growth and provide evidence of overwintering cell viability. Lines of evidence supporting algaecide efficacy for preventative treatments include (1) field studies demonstrating scalability and efficacy of algaecides against benthic algae, (2) data suggesting similar sensitivities of overwintering and planktonic Microcystis cells to a peroxide algaecide, and (3) a mesocosm study demonstrating a decrease in HAB severity following preventative treatments. This review informs data needs, monitoring techniques, and potential efficacy of algaecides for preventative treatments of overwintering cells.

Full text
Abstract:
Environmental, developmental, physiological and biochemical determinants of cucurbit seed quality were investigated in field and laboratory experiments. The major factor influencing seed quality is seed maturity at harvest, with both immature and overmature seeds exhibiting reduced quality. Planting density and fruit load per plant can be manipulated to maximize seed yield per unit area without adversely affecting seed quality. Seeds harvested at optimal maturity will have the greatest germination vigor and will maintain quality longer during storage. Seed priming can improve germination rates and uniformity, but can reduce storage life. Tissues enclosing the embryo (the endosperm envelope and seed coat) are involved in regulating germination. The seed coat (testa) may restrict oxygen diffusion to the embryo in some muskmelon genotypes. Weakening of the endosperm envelope is associated with radicle emergence. Callose deposition in the endosperm envelope results in semipermeability. Defense proteins such as chitinase are also present in the endosperm. Numerous genes were identified that are expressed specifically in association with germination, but their functions are yet to be elucidated. These studies have provided guidelines for producing and harvesting cucurbit seeds for maximum yield and quality and have identified physiological and biochemical processes contributing to seed germination vigor.
