Healthy Seed

Seed perform a vital role in agricultural sector for crop production as well as seed business. Scarcity of healthy seed hinder not only the crop production but also the quality of seed. Storing of healthy seed with proper storing condition is one of the suitable methods to maximize production however, healthy seed also lose its quality during seed storage. Seed remains viable for long time if the seed stored by maintaining seed moisture content, storage temperature with storage container. So, this experiment was carried out to observe the quality parameters of jute seed during long term storing. To find out the storage effect an experiment was conducted on march, 2020 at seed laboratory, Jute Agriculture Experimental Station, Jagir, Manikganj, Bangladesh during the period of January 2016 to March, 2020. Plastic pot was used in this experiment as a storage container to store jute seeds. Three tossa jute (C. olitorius L.) varieties viz., O-795 (V1), O-9897 (V2) and OM-1 (V3) were used in this study. Result revealed that storage period and jute variety showed significant effect on different seed quality parameters. The highest seed germination, field emergence, seed vigour and the lowest 1000-seed weight, moisture content were recorded in T5 (2019-20) treatment. On the other hand, the lowest seed germination, field emergence, seed vigour and the highest 1000-seed weight, moisture content were recorded in T1 (2015-2016) treatment. Furthermore, seed germination, field emergence, seed vigour was negatively but 1000-seed weight was positively correlate with moisture content. Results revealed that extended storage period caused the decreasing seed quality and seed can be stored for three years in plastic container without hampering the seed quality.

An experiment was conducted at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during April 2013 to June 2013 to study the effect of three storage containers (tin container, polythene bag and cloth bag); and five storage periods (0, 15, 30, 45, and 60 days) on the seed quality of soybean. The experiment was laid out in Completely Randomized Design (CRD) with four replications. The soybean seeds stored in tin container showed maximum germination capacity with high germination index, highest seedling growth, seedling dry weight per plant and vigour index. The seeds stored in cloth bag had the lowest seed quality during the testing period. The highest 1000-seed weight, moisture content, electrical conductivity, abnormal seedlings and number of dead seeds were recorded in cloth bag; where the equivalent lowest values were recorded in tin container. The moisture content, 1000-seed weight, electrical conductivity, number of abnormal seedlings and dead seeds were increased with the longer period of storage. In addition, germination index, seedling growth, dry weight per plant of soybean seedling, and vigor index decreased with the increase in storage period. Among the three containers, tin container was the best and the cloth bag was the worst storage container for soybean seed storage for long period.

SUMMARYSuccessful crop production depends initially on the availability of high-quality seed. By 2050 global climate change will have influenced crop yields, but will these changes affect seed quality? The present review examines the effects of elevated carbon dioxide (CO2) and temperature during seed production on three seed quality components: seed mass, germination and seed vigour.In response to elevated CO2, seed mass has been reported to both increase and decrease in C3plants, but not change in C4plants. Increases are greater in legumes than non-legumes, and there is considerable variation among species. Seed mass increases may result in a decrease of seed nitrogen (N) concentration in non-legumes. Increasing temperature may decrease seed mass because of an accelerated growth rate and reduced seed filling duration, but lower seed mass does not necessarily reduce seed germination or vigour.Like seed mass, reported seed germination responses to elevated CO2have been variable. The reported changes in seed C/N ratio can decrease seed protein content which may eventually lead to reduced viability. Conversely, increased ethylene production may stimulate germination in some species. High-temperature stress before developing seeds reach physiological maturity (PM) can reduce germination by inhibiting the ability of the plant to supply the assimilates necessary to synthesize the storage compounds required for germination.Nothing is known concerning the effects of elevated CO2on seed vigour. However, seed vigour can be reduced by high-temperature stress both before and after PM. High temperatures induce or increase the physiological deterioration of seeds. Limited evidence suggests that only short periods of high-temperature stress at critical seed development stages are required to reduce seed vigour, but further research is required.The predicted environmental changes will lead to losses of seed quality, particularly for seed vigour and possibly germination. The seed industry will need to consider management changes to minimize the risk of this occurring.

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.

Summary. The vigour of Welsh onion (Allium fistulosum L.) seeds with low moisture content was determined after exposure to different storage temperatures and container types. As the storage period was prolonged, the effects of storage temperature and container type on seed vigour became more pronounced. Storage temperature had a greater effect on seed vigour than container types, and the effect of the latter was subject to the storage temperature. When the seeds were stored in the same type of container, several indices of the seed vigour declined as the storage temperature increased. A highly significant positive correlation was evident between dehydrogenase activity and the percentage germination of the seed. Improving storage conditions could prolong seed longevity. If the seeds, in which the moisture content has been reduced to less than 6%, are stored airtight, the percentage germination will be about 85% after storage for 2 years at room temperature or after 3-year storage at 6°C. If the seeds are stored at –6°C, the percentage germination will range from 86 to 91% after 3-year storage, regardless of the storage container types in this study. These data are very important for the seed storage and germplasm conservation of Welsh onion.

<p>Glucosinolates (GS) are amino acid derived secondary metabolites present specifically in Brassicaceae family. The effect of altitude (2800 m - 4000 m) on GS contents and seed quality characteristics in radish (Raphanus sativus L.) was investigated. The total GS in radish seed was 147.5±21.5 μmol/g DW, which included five aliphatic and four indolic GS compounds. Increasing altitude was related linearly to increase in total GS contents (R2 = 0.759). Among individual GS, glucoraphanin and glucoraphenin showed consistently increasing trend with altitude. Increasing altitude is related linearly to increase in 100 seed weight (R2 = 0.266) and seed yield per plant (R2 = 0.849). A steady decreasing trend was observed in seed moisture content (R2 = 0.831) and siliqua length (R2 = 786) with increasing altitude. Altitude of plant origin was positively correlated with GS contents (r = 0.900, p≤ 0.01), seed weight per plant (r = 0.919, p≤ 0.01) and geometric mean diameter (r = 0.661, p≤ 0.01), and negatively correlated with siliqua length (r = -0.880, p≤ 0.01), moisture content (r = -0.884, p≤ 0.01) and seed vigour index (r = -0.547, p≤ 0.01). Our results indicate that the concentration of GS in radish seed and seed quality traits can be significantly increased by growing plants at higher altitude.</p>

Sorghum Bicolor L

A set of laboratory experiments were conducted to evaluate the physiological quality of Sorghum bicolor (L.) Moench seeds subjected to different field cultural management practices. The main aim of this study was to contribute towards improved production of Sorghum bicolor (L.) Moench through better understanding of the crop’s agronomy. The experimental design was a three factorial split-split block design in the rain fed Sorghum bicolor (L.) Moench producing areas of Bomet County of Kenya. Treatments within the block were randomized. There were three factors which included variety at two levels (improved and local varieties); fertilizer application at two levels (with and without fertilizer); and seed selection at three levels (continuous, from booting stage and at harvest). Percentages of crop emergence and days to 50% physiological maturity were determined. The following seed quality tests were carried out: 1000-seed weight, standard germination, mean germination time and electrical conductivity. The improved variety had a field emergence of 100% while that of the local variety ranged from 60 - 97%. In regard to field emergence and maturity, there were significance differences (P≤ 0.001) between plots with fertilizer and those without regardless of the variety. Those plots with fertilizer outperformed those without. Germination and vigour tests indicated that seed selection time did not influence seed vigour, viability and yield (P ≤ 0.05). However, there were significant differences (P ≤ 0.001) between the improved variety (E1291) and local (Ochuti) variety. In relation to this, variety E1291 showed better seed vigour, viability and yield as compared to Ochuti. Similarly, there were significant differences (P ≤ 0.001) between plots to which fertilizer was applied and those without. Fertilizer application led to an increase in seed yield, seed weight, seed vigour and viability. It was therefore concluded that (i) E1291 was more adapted to the study area as compared to Ochuti and hence should be adopted by farmers; (ii) farmers should apply optimal phosphate and nitrogenous fertilizers to their soils so as to increase the quality and yield of their seed; and (iii) farmers could continue selecting their seed using their indigenous knowledge.

<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>

Desiccation of plants by paraquat significantly reduced seed weight and germination at all locations and increased the incidence ofAlternariaandPhomopsisspp. at Urbana. Analysis of the combined data from the Brazilian locations showed a significant decrease in seed germination for all treatments except paraquat sprayed on the UFV2at R7and sodium chlorate: sodium borate sprayed on UFV1at R7. Herbicide application at R7did not result in consistent increases in seedborneFusariumorPhomopsisspp. at any Brazilian location. Rainfall and temperature at seed maturation were more important variables in pod-to-seed infection by these fungi than increased rates of tissue senescence caused by the desiccants.

Bean and okra are common vegetables cultivated in the most regions of Sri Lanka.  The seeds of these crops are mainly stored in cold storage as bulk before releasing retail lots to sales outlets. Commercial growers and gardeners buy seeds in bulk or in packages at retail stores. Although certified seeds are frequently tested by the seed testing laboratories, they do not guarantee the maximum field emergence. Certified seed lots of two pole bean varieties, ‘Keppetipola Nil’ (KN) and ‘Bandarawela Green’ (BG) and two okra varities,’MI-5’ and ‘Haritha’ were stored in poly sack and polypropylene bags under controlled temperature (17±1 °C) and relative humidity (RH) (52-55%) over a two-year period. Bulk seeds of bean and okra varieties packed in polypropylene and poly sack bags depicted a high germination percentage throughout the storage period for two years. Seed quality parameters, seed germination, seed moisture, field emergence and vigour index significantly varied with the storage duration and declined in varieties. Significant differences in moisture, field emergence and vigour index were recognized as affected by the packing materials in all varieties except MI-5. Both Poly sack and polypropylene packing materials were found suitable to maintain viability at the minimum seed certification standards for two years of storage period. Poly sack was more appropriate than polypropylene to keep viability for more than 2 years of storage under low temperature and RH condition. These findings would help seed handlers including seed producers and seed sellers to store crop seeds between growing seasons in the tropical environment.

Performance Differences

Herbage seed lots of the same chronological age, certification class and germination values often differ in performance in the field, in storage, or both. These performance differences are ascribed to another seed quality factor, seed vigour. Vigour differences have been shown to occur in New Zealand seed lots of Trifolium repens, T. pratense, Medicago sativa, Bromus willdenowii, Cynosurus cristatus and Festuca spp., and are highly likely to occur in all other herbage species. This review of vigour in herbage seed lots discusses the concept, its possible causes, the implications for sowing, storage and export of seed, and how seed lot vigour information might be used by the farmer, seed store manager and seed marketer.
