“…The loss of viability of seeds also associate with genetic damage (Pradhan & Badola, 2012) and the degree of damage depends on seed storage condition (Santos et al, 2016). This leads to the deterioration of the seeds (Chhabra et al, 2019). Proper storage conditions, however, may effectively retain substantial viability in seeds over a considerable storage period (Chen et al,2007;Pradhan & Badola, 2008).…”

One of the main causes of food insecurity is the timely unavailability of quality seeds for smallholder farmers in developing countries. Improved storage technologies are effective in reducing storage losses. Thus, the objective of this research is to assess the traditional and emerging seed storage structures/materials for the maintenance of seed qualities. The effect of different storage conditions (moisture content of seed at the time of storage, i.e. 12±0.15% and 13.5±0.18%; storage containers such as metal bin, earthen pot, Purdue Improved Crop Storage (PICS) bag, and jute bag) on seed qualities of maize were assessed. The seed was collected from Chitwan, Nepal and a laboratory experiment was conducted at the central seed testing laboratory, seed quality control center (SQQC), Hariharbhawan, Lalitpur. The experiment was done using a two-factor complete randomized design in a four replicates design. Data regarding the seed qualities (seed moisture percentage, germination percentage, root and shoot length, and vigor index) just before store and also at 45, 90, 135, 180, and 240 days after storage (DAS) was performed as per the standard followed by International Seed Testing Association (ISTA). The germination percentage, root, and shoot length decreased with increasing storage duration. The seed stored in the higher moisture level had significantly higher seed moisture throughout the storage duration. Seed stored in the traditional structures (jute bag and earthen pot) had lower seed moisture at 120 and 180 DAS. The seed stored at lower moisture resulted in a higher germination percentage, long root, and shoot length. Up to six months of storage germination of maize seeds stored in the earthen pots, PICS bag, and Jute bags were statistically similar. The traditional storage structures are equally effective for the maintenance of seed quality of maize.

“…The process of deterioration involves several physiological and structural changes within the seed. Structural changes involve membrane permeability, proteins, sugars, nucleic acids, fatty acids and volatile substances, while physiological processes involve enzyme activity, respiratory competence, lipid peroxidation and physiological repair mechanisms (Chhabra and Singh, 2019;Qun et al, 2007;Walters, 1998). According to Vertucci and Roos (1990), optimum protocols for seed storage must take into account the chemical composition of the seed, the physiological status of the seed and the physical status of water within the seed.…”

Background: Tomato is one of the most important vegetable crops in the world due to its dietary value. Harvesting and storing of physiologically matured tomato seeds is very important to secure good quality seeds for future use in a changing climate. The objective of the study was to assess the effect of maturity stages on seed quality of two tomato accessions during cold storage. Methods: Seeds of two tomato accessions extracted at four maturity stages (i.e. initially ripe, half ripe, fully ripe and rotten) were stored at -20oC in a deep freezer for 12 months. The quality of stored seeds was measured by seed vigour and germination percentage at 3, 6, 9 and 12 months after storage. Conclusion: The study showed significant differences in seed vigour and germination percentage at 3, 6, 9 and 12 months after storage (MAS) among the maturity stages. Seeds extracted at the initially ripe stage in GH 9305 had the least vigour at 3, 6, 9 and 12 MAS. The highest reduction in seed quality during the storage period was observed in seeds extracted at the rotten stage in both accessions. Seed vigour and germination were higher in GH 9207 than GH 9305. Storage of physiologically matured tomato seeds at freezing temperature is necessary to reduce seed ageing and to maintain high seed quality.

“…Changes in the activity of antioxidant enzymes are crucial biomarkers for observing biochemical changes during seed deterioration [29]. There are important changes in the activities of enzymes such as CAT, SOD and POD during the degradation and aging of seeds [30]. The AA test is a helpful tool for the study of different genotypes since the test simulates cell damage during prolonged storage and helpful to learn about the biochemical changes occurring in the seed [31].…”

Safflower is an important oleiferous crop species in the world. Aging tests are used to simulate cell damage occurring during the long term storage of seeds. In the present study, accelerated aging (AA) test was employed to investigate response of antioxidant enzymes in safflower. Four genotypes of safflower, previously classified as aging resistant (Bayer-6 and Bayer-12) and sensitive (Olas and Linas) based on AA test, were used as seed materials and AA treatments at 43 °C consisted of 5 different times (0, 48, 72, 96 and 120 h). Variance analysis were used and means were separated according to significance levels, and correlations were calculated between hydrogen peroxide (H2O2) content, superoxide dismutase (SOD) and catalase (CAT) activities. The H2O2 content, CAT, SOD and peroxidase (POD) activities were measured in control and AA treated seeds. Genotype, time and genotype x time interactions were all significant. While H2O2 content and SOD activity increased with AA time, CAT activity decreased in all genotypes throughout the experiment. POD did not show regular increase or decrease, its activity was specific to genotypes and time. Correlations between CAT activity and H2O2 content were significant negative for all genotypes, but between SOD activity and H2O2 content was positively correlated in AA treated seeds.
