Abstract. A study was conducted at four Village Development Committees (Masuriya, Udashipur, Basauti and Pahalmanpur) of Kailali dis- trict, Far western Region, Nepal in 2016/17 to find out the effect of different storage materials on the seed moisture content and germination percentage of wheat. Seeds of wheat were packed using five storage materials (metal seed bin, earthen pot, purdue improved crop storage / Pics/ bag, gunny bag and super grain bag). The stored seed samples were drawn at three-month intervals starting from May 2016 to January 2017. The experiment was arranged in Randomized Complete Block Design (RCBD) in four replications. The results of analysis of variance revealed that the effect of storage materials was significant (P≤0.05) on seed moisture content and seed germination of wheat. After nine months of storage, the seeds stored in Pics bag recorded the lowest moisture (13.3%) and temperature (26.4°C), and the highest germination percentage (91.75%). The lowest quality performance (high moisture and temperature, low germination) of stored seeds was observed in an earthen pot. From the results obtained, it was concluded that wheat seed could be stored for a long time in Pics bag without deteriorating its quality parameters.

Temperate-zone woody plant species generally require seed stratification to overcome embryo dormancy. Embryo dormancy is variable in japanese tree lilac (Syringa reticulata) with a recommendation of 30- to 90-days stratification at 1–5 °C. Cultivar propagation generally is done by grafting onto seedling rootstocks. It would be advantageous to rootstock seedling production to be able to reduce or eliminate the need for seed stratification to increase germination numbers as well as having production moved from field beds to greenhouses for quicker production of high-quality rootstock plants suitable for grafting. Research objective of this study was to determine if “green” seed could be used without the need of stratification for japanese tree lilac seedling production. Seed capsule fresh weight and seed moisture content were evaluated to determine if these factors could be used as predictors of germination percentages. Seed was randomly collected at the North Dakota State University campus in Fargo, ND, for seven consecutive weeks starting in Sept. 2011 and 2012. Germination and seed moisture tests were performed weekly. Germination percentage was highest (89.5%) at week 2 and steadily decreased to 0% at week 7. Germination percentages were 77.5%, 89.5%, 78.5%, 67%, 24.5%, 1.5%, and 0% for consecutive collection weeks 1–7, respectively. Seed moisture content was 59.0%, 52.6%, 49.8%, 51.8%, 44.5%, 27.4%, and 8.6% for collection weeks 1–7, respectively. Germination percentage was directly correlated with seed moisture content and decreased as seed capsules matured (natural drying and splitting of capsule seem to disperse seed) during the fall season. Data suggest that timing of fall seed collection from japanese tree lilac is critical and must be done before maturation of the seed capsule to avoid the stratification requirement. Seed capsules with an average fresh weight higher than 0.2 g and seed moisture content greater than 50% produced the highest germination rates without requiring stratification.

Fungal incidence in stored common bean (Phaseolus vulgaris L.) is the main concern in order to preserve seed health and viability. The main aim of this study was to analyse these quality parameters in hermetically stored seeds at 10.2, 13.1, 16.2, 18.5% moisture content (MC) and 25, 30, 35, 40°C, through seed germination and health tests. Water activity recorded at 10.2 and 18.5% MC were 0.448 and 0.700, respectively. Low seed moisture content reduced Alternaria spp. incidence at 25-30°C. Highest incidence of Fusarium spp. (7.5%) occurred at 16.2% MC and 35-40°C. Highest incidences of Rhizoctonia spp. (8-10%) were recorded at 16.2-18.5% MC and 30-40°C. Penicillium spp. and Aspergillus spp. were predominant throughout the experiment and the highest incidences (80-100%; 20-30%, respectively) were scored at 18.5% MC and 30-35°C and 13.1-18.5% MC at 35°C, respectively. The higher the seed MC the higher the fungi incidence while lower seed MC decreased the incidences by 25%. Storage conditions below 30°C and 13.0% MC appear suitable to preserve common bean seed in relation to viability and health, up to a 8-month period.

The present investigation was carried out in laboratory of the Department of Seed Science and Technolo-gy, College of Agriculture, Junagadh Agricultural University, Junagadh from the April 2013 to April 2015, wherein two kg of freshly harvested quality seed of soybean cv. Gujarat Junagadh Soybean 3 having high germination percentage and low moisture content (below 8%) was taken for each repetition and for each combination of treat-ments. The treatment consisted of two storage conditions (C) viz., C1 (Ambient temperature) and C2 (Cold storage at 7oC + 2oC), and five seed treatments (S) viz., S1 = Control, S2 = Carbendazim @ 2g/kg seed, S3 = Mancozeb @ 2g/ kg seed, S4 = Neem leaf powder @ 10g/kg seed, and S5 = Neem Oil @ 5 ml/kg seed. The experiment was carried out using Completely Randomized Design (Factorial) repeated three times. After proper mixing or smearing the seeds as per the treatments, seeds were packed in cloth bag and kept in laboratory under two different storage conditions. Observations were recorded at 90 days interval on germination (%), root length (cm), shoot length (cm), seedling dry weight (g), seed vigour index I, seed vigour index II and seed moisture content (%). The results revealed that storage condition (C) and seed treatments (S) exhibited significant differences almost for the all the traits for germination and seedling parameters after 2 years of storage. The results of soybean seed stored in two different storage conditions showed that on an average, the seed stored under cold storage (70C + 20C) noted higher values for all the traits studied except seed moisture content after 2 years of storage. Among the seed treatments, on an average, after 2 years of seed storage, significantly (P<0.05) higher values were recorded by all the seed treatments over the control. However, seed treated with Mancozeb @ 2g/kg of seed recorded the significantly highest germination percentage (71.50 %) and it was at par with Neem leaf powder @ 10 g / kg seed (70.67%) and Carbendazim @ 2g /kg seed (69.67%) after 2 years of storage. The germination percentage noted in control treatment was 33.17 per cent after 2 years of storage. An ISTA standard for germination in soybean is 70 per cent. Most of the interactions effects were found significant (P<0.05) for all the traits studied.

In order to study the genetic changes which occur during seed storage, barley (Hordeum vulgare L. 'Himalaya') seeds were subjected to artificial aging using six combinations of temperature (21 °C, 32 °C, and 38 °C) and seed moisture content (12% and 18%). With increasing time in storage, germination of the seeds was delayed and reduced. Abnormal seedlings without roots also occurred with increased storage. Higher temperature and seed moisture content induced rapid loss of germinability. At the first mitotic division in the root tips, the frequency of aberrant anaphases and of roots with aberrations increased with increased storage time. The frequencies of aberrant anaphases and of roots with aberrations were also increased by higher temperature and seed moisture content. Frequencies of aberrant anaphases and of roots with aberrations were negatively correlated with germination percentage. This indicated that the frequency of chromosomal aberrations induced by seed aging might be estimated from the germination percentages.

Knowledge about seed storage behavior is important to preserve plant species. Clitoria fairchildiana R.A.Howard is an endemic species with medicinal properties, it is used in the recovery of degraded land. The objective of this study is to evaluate the effect of drying on the physiological quality of C. fairchildiana seeds. Seeds were oven dried along with silica gel for 18 days and in intervals of 2 or 3 days, samples were removed to assess the seed moisture content. This was done in an oven at 105±3 oC for 24h, using four replicates with 10 seeds each. After undergoing the above-mentioned treatment, a sample of seeds was stored in the freezer (-18 ºC) for 3 months. Sowing was carried out in plastic trays in a sand and sawdust mixture (1:1), previously sterilized in hot water (100 oC) for two hours. Seeds were left to germinate in a laboratory with no temperature and relative humidity control. Germination tests were performed over 14 days with daily counts of the number of emerged seedlings. The percentage of seed germination, abnormal seedlings and dead seeds were obtained 14 days after sowing. The experimental design was completely randomized with four replications of 25 seeds. The reduction of seed moisture content from 18.5% to 5.6% affected physiological seed quality causing a reduction in the germination percentage and an increase in dead seeds and abnormal seedling percentage. C. fairchildiana seeds are classified as intermediate and they can be desiccated up to 8.6% with no reduction in physiology quality.


Rice is the staple food of more than half the world’s population and is being cultivated in Asia since ancient time’s generation after generation. Good quality seeds are the seeds of the green revolution, it has been assertively and emphatically shown that 15-20% increased yield could be achieved by the use of good quality seeds alone. Good quality seed is one of the most important requirements for production and supply to achieve higher production and productivity in any crop. The seed quality is depended on various factors Viz. genetic, edaphic, environmental, biotic, etc. Good quality seed production depends on complex conditions evoking the most favorable interactions between the genetic makeup of the seed and the environment, under which it is produced, harvested, processed, and stored. Seeds undergo deterioration at various levels during storage resulting in a decline in vigor and viability. With the above considerations, the present investigation has been undertaken to observe the potentials of ten rice genotypes and observed its seed quality after harvesting in 2016-2017 at Seed Testing Laboratory, Department of Seed Science and Technology, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, West Bengal, India. Just after harvesting G2 (Gobindabhog) and G9 (IR-36) showed highest germination percentage (97.66) and G9 (IR-36) showed highest Vigor index (3204.13). But most of the varieties germination and vigor were nearer to G2 & G9. Among the containers with seed moisture content aluminum foil packet with seed moisture content, 8% is the best storage container for rice among the other containers as up to one-year storage vigor index was observed highest in that conditions.

AbstractThe correlation between the sowing value of primed China aster seeds represented by germination percentage (GP), mean germination time (MGT), germination uniformity expressed as the time between 25% and 75% of germinated seeds (T75-25) and some selected physiological characteristics - total activity of dehydrogenases (TAD), activity of catalase (AC), activity of cell cycle (ACC) and electrolyte leakage (EL) has been analysed in order to find useful markers of biological quality of seeds. To achieve this objective, analyses of effects of three methods of water supply to seeds viz. - hydroconditioning by soaking in excessive amount of water (M1), hydroconditioning by soaking in limited amount of water (M2) or hydroconditioning by contact with solid carrier of water - matriconditioning (M3), three levels (30.0, 35.0 and 40.0%) of seed moisture content (m.c.) and three incubation periods (1, 8 and 10 days) during priming and hence their influence on germination properties (GP, MGT, T75-25) in comparison with TAD, AC, ACC and EL were determined. The results showed that MGT and T75-25 were correlated with TAD, AC, ACC and EL, irrespective of their priming method and sowing value. Therefore, all the investigated physiological/biochemical parameters of seed quality can be used as markers of germinability and sowing value reached by primed China aster seeds. The results also proved that, irrespective of the water supply method applied, hydration of seeds up to 37.5% m.c., and their incubation at 20 °C for 8 days, followed by drying to their initial moisture content, increased to the greatest extent the speed and uniformity of seed germination and their physiological activity.

Abstract: The objective of this study was to evaluate the production, and the physical and physiological quality of ‘BRS Aleppo’ chickpea seeds in the city of Montes Claros, Minas Gerais State, and their ideal harvest point. A randomized complete block design was used, in a 3x5 factorial arrangement, with three sowing periods (May 12th, June 23rd and July 22nd 2015) and five harvest seasons (100, 107, 114, 121 and 128 days after sowing) with seven replications. The following productive parameters were determined: number of seeds, number of empty pods, production and yield. For seed quality evaluations, the completely randomized design was used. The following evaluations were done: seed moisture content, dry matter, biometry, 1,000-seed weight and germination. For the harvest season factor, data were submitted to analysis of variance and comparisons average by Tukey’s test (p<0.05). The regression analysis was performed and coefficients were tested with the t-test. Seed production was higher when sowing was done in May and when the harvest was performed close to 114 days after sowing, with a yield reaching 5.31 ton/ha-1 and 10.7% seed moisture content. If sowing is delayed, there is a risk of rainfall during the harvest season, and seed quality is compromised.

An experiment was conducted at the Seed Laboratory of Regional Agricultural Research Station (RARS), Jamalpur during the period from May to November 2010 to study the effect of thickness of polythene bags on quality of soybean seed during storage. Seven levels of thickness of polythene bags viz. i) 0.02mm, ii) 0.03mm, iii) 0.04mm, iv) 0.05mm, v) 0.06mm, vi) 0.07mm and vii) 0.08mm were include as treatment in the trial. Seed moisture content, germination percentage, vigor and seedling dry matter weight were taken during May to November 2010 at two month intervals. Results showed that during the storage period the lowest seed moisture content and highest germination percentage, vigor index, seedling dry matter weight and field emergence were found for seed stored in 0.08mm thickness polythene bags. The germination of seed at two months after storage ranged between 76% to 95.3% and that was between 0% and 90.7% after six months of storage under ambient room condition. Soybean seed could be stored safely at ambient condition with more than 80% germination for six months by keeping them in polythene bags having thickness between 0.03mm to 0.08mm with 8% seed moisture content.

To find out the effect of storage relative humidity, seed moisture content and type of storage container on soybean seed quality, an experiment was conducted at the Seed Laboratory, Department of Agronomy, Bangladesh Agricultural University Mymensingh in 2008 and 2009. In 2008, soybean seed has 96% initial germination and in 2009 seed having 98% initial germination was stored at 8% and 12% initial moisture levels in two types of storage containers viz., cloth bag and polythene bag (0.06mm thickness). The final seed moisture content, germination percentage, germination index, and seedling dry matter of the seed under different treatments were measured at 60,120, and 180 days after storage (DAS). The experiment was arranged in a completely randomized design with three replications. In 2008, highest germination percentage (89.33%) of soybean seed was retained at 180 days after storage (DAS) for those stored at 8% initial seed moisture content (SMC) in polythene bag at 50% relative humidity. Germination index and seedling dry matter decreased with increased initial seed moisture content irrespective of storage containers used. In 2009, highest germination percentage (92.67%) of soybean seed was retained at 180 DAS for those stored in polythene bag at 8% initial SMC at 50% of the relative humidity. Those stored in cloth bag at 12% SMC showed rapid germination loss and the value went down to 0.00 in both the years. Vigour index and seedling dry matter decreased with increased initial seed moisture content irrespective of storage containers used. DOI: http://dx.doi.org/10.3329/bjar.v39i3.21989 Bangladesh J.
