<p>Soybean seed viability declines during seed storage. Soybean seed deteriorates rapidly, affected by its high protein content and often high humidity in the tropical environment. This research was aimed to develop dynamic model of soybean seed viability in an open storage. The study was conducted in three stages, namely: 1) desk study, 2) seed storage experiment, 3) development of seed storage model, simulation and verification of the model. The second stage of the experiment consisted of soybean seed storing and germination testing using completely randomized design. Treatments were three initial moisture content (7-8%, 9-10% and 11-12%) and four varieties of soybean (Anjasmoro, Wilis, Detam-1 and Detam-2). The results showed that the seed behaviour during storage period were affected by initial seed moisture content, initial viability, varieties and environmental condition. Therefore, seed moisture content, initial viability and varieties may be used as input model. Moisture content, integreting seed respiration, electric conductivity and seed storability vigor (VDSDB) were as model output. Simulation of Seed Storability Vigor Prediction Model with Model Construction Layer-Stella (MCLS) using relative humidity (RH), temperature, seed permeability, initial moisture content and initial viability as input model could logically predict the seed moisture content and seed storability vigor (VDSDB).</p>

Abstract Background: Globally, forestry faces challenges in the availability of seeds due to limited knowledge on seed handling of various species. Forestry seeds are constantly being reviewed and classified as either recalcitrant, intermediate, or orthodox based on their storage behavior. It is essential to understand the tree seed storage behavior to maintain seed viability and thus minimize seed losses. There is scanty literature combining factors of seed moisture content (6%, 9%, 12%, 15%, and 20%), seed storage temperature (20oC, 5oC and -20oC), seed storage duration (1, 4, 9 and 12 months), and germination in different sites with varying environmental variables. Ehretia cymosa is important in the Afromontane forestry landscape as a medicinal, rehabilitation, and conservation species. This study conducted desiccation and storage studies and their influence on the viability of E. cymosa seeds. The study sought to determine the optimum conditions for the storage of Ehretia cymosa that maintains viability. Results: This study observed that E. cymosa dried to seed moisture content of 6%, stored for 12 months at 20oC and sown in the laboratory had the highest germination performance (27.6 ± 3.18%) (p<0.05). Conclusion: This confirms that E.cymosa seeds exhibit orthodox storage behavior. The authors recommend longer storage studies (>12months) to determine the actual longevity of the seeds of this species. The significance of these results would be useful for foresters and farmers that would need to use this species for various purposes.

The present study examined the effect of temperature (15, 20, 25, 30 and 20/30°C) on germination and the storage behaviour of freshly harvested mature seeds of Calamus palustris var. cochinchinensis. Seed desiccation tolerance and the effects of storage temperature (4 and 15°C), perlite water content (120, 180 and 240%) and seed moisture content (27.8, 38.2 and 49.2%) on viability were observed. Seeds had a higher germination at 25°C (88.3%) than at the other tested temperatures. Germination decreased as the seed moisture content decreased during desiccation. The germination of seeds stored at 15°C was higher than that of seeds stored at 4°C. Germination of seeds stored at 15 and 4°C was <65% and with extension of storage time, the germination decreased, indicating that neither temperature can be used for long-term conservation. For short-term storage, the seeds can be stored at 15°C with perlite with 180% water content in plastic bottles or at 15°C with 49.2% moisture content sealed inside aluminum foil bags.

The objective of this work was to determine the viability equation constants for cottonseed and to detect the occurrence and depletion of hardseededness. Three seedlots of Brazilian cultivars IAC-19 and IAC-20 were tested, using 12 moisture content levels, ranging from 2.2 to 21.7% and three storage temperatures, 40, 50 and 65ºC. Seed moisture content level was reached from the initial value (around 8.8%) either by rehydration, in a closed container, or by drying in desiccators containing silica gel, both at 20ºC. Twelve seed subsamples for each moisture content/temperature treatment were sealed in laminated aluminium-foil packets and stored in incubators at those temperatures, until complete survival curves were obtained. Seed equilibrium relative humidity was recorded. Hardseededness was detected at moisture content levels below 6% and its releasing was achieved either naturally, during storage period, or artificially through seed coat removal. The viability equation quantified the response of seed longevity to storage environment well with K E = 9.240, C W = 5.190, C H = 0.03965 and C Q = 0.000426. The lower limit estimated for application of this equation at 65ºC was 3.6% moisture content.

Commercialisation of many Australian everlasting daisy (Asteraceae) species islimited by poor germination, due in part to dormancy. This study examined theeffect of storage temperatures of 5, 15, 25 and 38°C on seed viability andgerminability of Schoenia filifolia subsp.subulifolia, Rhodanthe chlorocephala subsp.rosea and an unnamed species ofCraspedia. Short-term storage (< 18 months) at cooltemperatures increased seed moisture content, reduced viability and did notpromote germination. However, storage at high temperatures decreased seedmoisture content, maintained viability and improved germination. In tests oflong-term (> 24 months) storage in ambient conditions, both viability andgerminability declined in cohorts of Schoenia andRhodanthe. Detailed tests on 8-month-old seeds ofSchoenia revealed that dormancy was not due tomechanical barriers, as scarification did not improve germination. However,gibberellic acid (GA3) and KNO3applications overcame the dry-storage requirement to break dormancy in thisspecies. High-temperature, dry storage is an important treatment to breakdormancy for planting arid-zone Asteraceae seeds of less than 6 months of age.

Soybean (Glycine max) seed loses its viability in the storage which causes shortage in supply of quality seed and consequently hinders the expansion of soybean cultivation in Bangladesh.Losses of seed viability of soybean (Glycine max) in traditional storage is very common in the tropical environment. An experiment was conducted at the Seed Laboratory, Regional Agricultural Research Station, Bangladesh Agricultural Research Institute (BARI), Jamalpur in 2011 and 2012 to find out the effect of seed moisture content and types of storage container on soybean seed germination and seedling vigour. In 2011, soybean seed having 94% initial germination was stored at 8, 10 and 12% moisture levels but in 2012 seeds having 96% initial germination was stored at 6, 8, 10 and 12% initial moisture levels in four different types of storage containers viz., polythene bag, plastic pot, tin can and glass jar. weredays after storage ().The experiment was arranged in a factorial completely randomized design with three replications. In 2011, high germination of soybean seed (77-85%) was retained at 200 DAS for those stored at 8% initial seed moisture content (SMC) in any of the containers. Germination index and seedling dry matter decreased with increased initial seed moisture content irrespective of storage containers used. Tin preserved higher seed moisture contents of 9.93, 11.71 and 14.15% for seed stored at 8%, 10% and 12% initial seed moisture content, respectively. In 2012, 80-94% seed germination was retained at 200 DAS for those stored at 6% initial SMC in any of the containers. The germination declined to a range between 75.0 and 91.3% within 200 DAS at 8% initial SMC while those stored at 12% SMC showed rapid germination loss and the value showed down to between 9.3 and 22.0%. Vigour index and seedling dry matter decreased with increased initial seed moisture content irrespective of storage containers used. Tin also Seeds stored in tin container showed the higher final seed moisture contents irrespective of initial seed moisture content. Bangladesh Agron. J. 2018, 21(1): 131-141

Seed Moisture

Water is pervasively involved in the life cycle of seeds. Water in the environment, either as a vapor or liquid, directly affects seed moisture status. This article is devoted to the study of seed moisture status in postharvest events. Two topics are discussed: imbibitional chilling injury and upgrading of primed seeds. Imbibitional chilling injury is a physiological disorder that occurs in large-seeded legumes as well as other important agronomic seeds. Imbibitional chilling injury has been shown to reduce the survival rate of seedlings. Surviving seedlings have less emergence force per seedling and require a longer period to generate maximum force. Rapid hydration has been shown to induce injury at a particular seed moisture level. Methods of regulating the hydration rate were explored to alleviate chilling injury in snap beans (Phaseolus vulgaris L.) Plant breeding lines with the semihard seed characteristic delayed the onset of imbibition when the initial moisture level was low (8%). Coating seeds with polymeric films to complement the permeable testa retarded the imbibition rates. Both approaches alleviated chilling injury and improved seedling establishment under stressful conditions. Seed priming is a technique for elevation of seed moisture content before sowing. Primed seeds generally emerge more quickly than nonprimed seeds, especially under stressful environmental conditions. An additional merit of this technique is that it gives access to seeds with elevated moisture content. Various approaches may be employed to condition seeds after priming, but before redesiccation. Discarding the low-density fractions of primed tomato and lettuce seeds improved the percentage of germination compared with nonprimed seeds. Physiological mechanisms are presented to explain the association of density with seed viability in lettuce (Lactuca sativa L.).

Deterioration of seeds during storage may reduce the supply of high-quality seeds which become the limiting ‎factor of soybean production in tropical countries. Controlled Deterioration Test (CDT) is one of the ‎fastest vigor testing methods. The objective of this study was to achieve the suitable moisture content and ‎duration of CDT treatment in soybean seed, then establish a model that associated with the seed vigor in ‎the field after a certain time of storage. Split-plot with 2 factors, namely seed varieties and the combination of ‎moisture content and heat exposure duration were used to determine the influence of CDT treatment. ‎Another split-plot for 2 factors, namely storage period and seed varieties were used to determine the effect ‎of shelf life. Viability parameters were observed by germination strength (GS) and seedling vigor index (VI), ‎using a rolled paper towel method. The results showed that there was an interaction between soybean seed ‎varieties and the combination of seed moisture content treatment with duration of CDT exposure. Sindoro ‎and Tanggamus varieties had higher viability and storability than other varieties. Combinations of 28% seed ‎moisture content for 24 hours CDT duration were sensitive enough to evaluate the physiological potential of ‎soybean seeds, providing information that was closely related to seed germination after stored for 1 month. ‎
