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.

<p>ABSTRACT<br />Information of seed quality during storage can be determined through the actual storage and storability vigor estimation. This study aimed at comparing effective accelerated aging method<br />between physical and chemical, and studying the seed deterioration during storage in ambient (T =28-30 0C, RH=75-78%) and AC (T =18-20 0C, RH =51-60%) condition with three levels of initial moisture content (8-10%, 10-12%, and 12-14%) for 20 weeks. The final objective of this research<br />was to develop model for storability vigor of papaya seed. Two experiments, accelerated aging and seed storage were conducted at Seed Laboratory, Department of Agronomy and Horticulture, Bogor Agricultural University from October 2015 to May 2016. A completely randomized design with nested factors and four replications was applied to both experiments. The results showed that physical accelerated aging using IPB 77-1 MMM machine was more effective than chemical accelerated aging using IPB 77-1 MM machine for papaya seed. The viability of seed stored in AC condition remained high until the end of the storage period, whereas it declined at 16 week storage period in the ambient condition. The viability of seed with initial moisture content of 12-14% declined faster than that of initial moisture content of 8-10% after 18 week storage periode. The model used to estimate the storability vigor of papaya seed accurately was the equation y = a + b expcx where y : storability vigor estimation, x : aging time and a,b,c : constant value. Simulation of storability vigor estimation with constant value of a, b, c and input of aging time can estimate storability seed vigor in actual storage.<br />Keywords: accelerated aging, IPB 77-1 MM machine, IPB 77-1 MMM machine, seed storage, simulation</p><p>ABSTRAK<br />Informasi mutu benih selama penyimpanan dapat diketahui melalui penyimpanan secara aktual dan pendugaan vigor daya simpan. Penelitian ini bertujuan untuk membandingkan metode<br />pengusangan cepat yang efektif antara fisik dengan kimia serta mempelajari pola penurunan viabilitas benih selama penyimpanan aktual pada kondisi simpan kamar (suhu =28-30 0C, RH =75-78%) dan AC (suhu =18-20 0C, RH =51-60%) dengan tiga tingkat kadar air awal (8-10%, 10-12%, dan 12-14%) selama 20 minggu. Tujuan akhirnya adalah membangun model vigor daya simpan benih pepaya. Penelitian pengusangan cepat dan penyimpanan dilakukan pada bulan Oktober 2015 sampai Mei 2016 di Laboratorium Benih, Departemen Agronomi dan Hortikultura, Institut Pertanian<br />Bogor. Kedua penelitian menggunakan rancangan acak lengkap tersarang dengan empat ulangan. Hasil penelitian menunjukkan bahwa pengusangan cepat secara fisik dengan alat IPB 77-1 MMM lebih efektif daripada pengusangan kimia dengan alat IPB 77-1 MM untuk benih pepaya. Viabilitas benih yang disimpan pada kondisi AC tetap tinggi hingga akhir periode simpan, sedangkan pada kondisi kamar penurunan viabilitas dimulai pada periode simpan 16 minggu. Benih yang disimpan dengan tingkat KA awal sebesar 12-14% lebih cepat mengalami penurunan viabilitas mulai periode simpan 18 minggu dibandingkan dengan benih dengan KA awal 8-10%. Hasil penelitian juga menunjukkan terdapat korelasi yang erat antara pola kemunduran benih pada pengusangan cepat dan penyimpanan aktual, sehingga model pendugaan vigor daya simpan (y) berdasarkan waktu pengusangan (x) dapat disusun dengan persamaan y = a + b expcx. Simulasi pendugaan vigor daya simpan dengan nilai konstanta a, b, dan c serta input waktu pengusangan dapat menduga vigor daya simpan benih selama penyimpanan aktual.<br />Kata kunci: alat IPB 77-1 MM, alat IPB 77-1 MMM, pengusangan cepat, penyimpanan benih,<br />simulasi</p>

<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>

AbstractSeed moisture content (SMC) is an important attribute to seed quality. Maintaining seed dryness throughout supply chain (The Dry Chain) prevents seed germination and quality losses. Ambient relative humidity (RH) and temperature affect seed moisture and thereof seed moisture isotherm. Present study was conducted to compare the moisture adsorption isotherms of wheat, maize, cotton and quinoa seeds packed in hermetic Super Bag and traditional packaging materials including paper, polypropylene (PP), jute and cloth bags. Seeds were incubated at 60, 70, 80 and 90% static RH. Nearly straight line moisture isotherms for all crop seeds were obtained in Super Bag. Seed moisture contents increased in traditional packaging materials with increasing RH. At higher level of RH, moisture contents increased slightly (1-2%) in Super Bag, whereas this increase was much higher in traditional packaging materials (≈9% higher than original SMC at 90% RH). In second study, seeds were dried to 8 and 14% initial seed moisture contents using zeolite drying beads and were stored in hermetic and traditional bags for a period of 18 months. For all crop seeds, germination was severely affected in all packaging materials both at 8 and 14% initial SMC except storage in Super Bag at 8% SMC. Wheat seed stored in Super Bag at 8% SMC almost maintained initial germination while germination of cotton, maize and quinoa seeds declined 7%, 14% and 30% respectively in Super Bag at 8% SMC. Seed storage in Super Bag can help to prevent the significant increase in seed moisture at higher RH as is evident from moisture isotherm study, thus helps to preserve quality of maize, wheat, cotton and quinoa seeds by maintaining The Dry Chain throughout the storage period.

Deterioration of bean seed quality in storage is a problem for consumers, seed producers, and growers. Research was conducted to evaluate imbibition and germination of dry bean seed cultivars/lines stored under conditions similar to those used by small farmers in the Dominican Republic. Eight dry bean cultivars and lines were grown at three locations in the Dominican Republic. Seed samples were stored in jute bags, plastic containers, and metallic cans under uncontrolled conditions in a small wooden building with slatted shelves. Sub-samples of seeds were taken at 2, 4 and 6 months to determine changes in moisture content, imbibition and germination. Mean cooking time values were determined for seed of four cultivars which had been stored in the three types of above mentioned containers for 6 months. Seed moisture content decreased from 11 to 7% during 2 to 6 months of storage for 'Venezuela 44' and 'ICA-Pijao', respectively. Seed of 'Constanza' had the lowest imbibition value. Imbibition value differed among cultivars for seed stored in different container types. Germination of "Venezuela 44' exceeded 90%, but was only 66% for 'José Beta'. At 6 months, the germination viability of seed stored in jute bags and plastic containers was 78% and 83%, respectively, whereas seed stored in metallic containers was 92% viable. Seed of 'Venezuela 44' had shorter cooking times than seed of the other cultivars. Cooking time of seed differed among container types. Results indicate that growing location, cultivars, storage containers and duration of seed storage can affect seed quality of beans in the Dominican Republic.

A study was undertaken to determine the prevalence of black point and percentages of germination, moisture content and different fungi associated with wheat seeds during storage in different types of container. Seeds of a widely cultivated variety Kanchan were stored in five types of containers viz., ‘dole'(bamboo made), earthen pitcher, tin container, polyethylene bag and refrigerator (10°C) for ten months at room temperature. Samples were taken at monthly interval beginning from the month of April (prior to storage). The seed moisture content and black point severity were found highest in dole resulting in the lowest percentage of seed germination. The highest germination percentage was observed under storage in refrigerator followed by polyethylene bag, tin container and earthen pitcher. The moisture content and black point infection increased and seed germination decreased with the increase of storage period. Prior to storage in April, the seed germination was 95%, which decreased to about 75% at the end often months of storage (in January). Various fungal flora associated with wheat seeds differed in their prevalence depending on the length of storage period and types of container used for storage. The population of field fungi viz., Alternaria alternata, Aiternaria triticina, Bipolaris sorokiniana, Cladosporium cladosporioides, Curvularia lunata, Epicoccum purpurascens and Fusarium spp. decreased while that of storage fungi viz., Aspergillus, Chaetomium, Nigrospora, Penicillium and Rhizopus increased with the progress of storage period.

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.

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 A laboratory experiment was conducted at the Department of Agronomy, Hajee Mohammad Danesh Science and Technology University, Dianjpur-5200, Bangladesh to evaluate the storage containers and duration of seed storage on the germinability and health of wheat seeds. The experiment was carried out in two factors, viz. three storage containers naming i) sealed tin container, ii) plastic container, iii) gunny bag, and four storage periods of i) 15 days, ii) 30 days, iii) 45 days, and iv) 60 days. Completely randomized design (CRD) was used in this experiment with eight replications. The results revealed that the germination percentages (GP) of the seeds stored in the gunny bag decreased quickly from 66.1 to 32.8% due to contained with high moisture content in seed. But, slowly decreasing trends of GP from 80.4% to 69.2% was observed in the sealed tin container seeds with lesser moisture content than that of gunny bag and plastic container. The reduction of GP was so higher of 50.38% in the seeds contained in gunny bag than that of only 13.93% in the seeds contained sealed tin container. Wheat seeds stored in sealed tin container, plastic container and gunny bag significantly increased moisture content in ambient condition for 60 DAS. The moisture content of the seeds stored in gunny bag was found to rise remarkably more than other containers. This escalation of seed moisture content was closely related to the surrounding environmental conditions, like temperature and relative humidity where seeds were stored. The rate seed deterioration in gunny bag and plastic container paralleled the level of invasion by storage insect was found. During storage period, insect infected the seeds, and the insect bitten seeds were also found higher in gunny bag and plastic container, but lower in sealed container. Wheat seeds should be stored in air tight sealed container and drying should be done after some days of storage (45-60 DAS).

Trials on the cultivars Canyon and Gallatin 50 in 1978 and Cascade in 1979 were run in North Queensland to examine ways of improving seed quality of snap beans. The trials concentrated on the maturation period, since this is a critical period for the development of seed quality. We found that seed quality was poor when the crop was cut at the stage when the leaves had fallen and all the pods were dry, or if the plants were cut at any stage and allowed to dry on the ground in single rows. This poor seed quality was associated with high pod temperatures during seed maturation. Cutting the crop before leaf fall, at a seed moisture content close to 50% (20-40% of pods dry) and windrowing immediately in 5 or 10 rows to 1 windrow gave low pod temperatures during seed maturation and high seed quality. Seed harvested and threshed directly off the crop was of good quality provided the seed moisture content in the crop had fallen to less than 25%.

Seed quality may be affected by several factors, including permeability, color, and lignin content in the seed coat. This study aimed at evaluating influence of lignin content in the tegument of seed samples of six different soybean cultivars, in which half of each sample was inoculated with the fungus Aspergillus flavus, on the physical and physiological quality, and on the seed health, during 180 days storage period, under cold chamber with controlled conditions of temperature and RH. For that, at each interval of 60 days, samples were removed, and the physiological quality of these seeds was assessed by means of moisture and lignin contents; and by tests of seed health, germination, and electrical conductivity. The moisture content of seeds remained constant during all storage period. In the seed health test, it was found that inoculation was efficient, once the minimum incidence of the fungus in the inoculated seeds was 85%. In the germination test, there was a trend of reduction on percentage germination with the increase in storage period. However, there was an increase on electrical conductivity of seeds assessed. It was concluded that there is no interference of the lignin content in the seed coat on the resistance to infection by the fungus Aspergillus flavus, even after seed storage for a period of 180 days.
