“…In ‘TSK 11’, enhanced germination and vigor were associated with SOD and APX activities, whereas in ‘PS 54’, the enhancement was related to SOD, POD, and APX activities (Table 1). Increased activities of SOD, CAT, APX, and glutathione reductase have been associated with improved emergence of primed sh ‐ 2 sweet corn seeds (Chiu et al, 2003) and purple coneflower seeds (Chiu et al, 2006). The difference in antioxidant enzyme activities induced by hydropriming between two lines is suggested to be caused by their different genotype.…”

Loss of Maize Seed Vigor as Affected by Biochemical Changes during Hydropriming

Hydropriming has both positive and negative effects on seed performance. Hydropriming (for 6 to 30 h) was performed in the maize {Zea mays L.) seed iines TSK 11' and 'PS 54'. A short hydropriming time of 6 to 12 h improved seed germination in both lines. An improvement in seed vigor, as investigated by germination after accelerated aging, was observed after hydropriming for 6 and 12 h in TSK 11' seeds, but only after 6 h of hydropriming in 'PS 54'. The reduction in seed vigor occurred faster in 'PS 54' than in 'TSK 11', which was confirmed at hydropriming times of 12 and 18 h, respectively. The higher activities of antioxidant enzymes, that is, Superoxide dismufase (SOD) and ascorbate peroxidase (APX) in 'TSK 11', and SOD, peroxidase (POD), and APX in 'PS 54', correlated with enhanced maize seed vigor after priming. The deterioration of primed maize seeds was linked to the process of lipid peroxidation, indicated by the generation of malondialdehyde during imbibition, and acetaldehyde and ethanol during redrying. Additional indicators were identified: a reduction in the antioxidant activities of SOD, GAT, and APX for 'TSK 11 ', and SOD and CAT for 'PS 54', decreased raffinose content, and increased amylase activity. A less compact cellular ultrastructure was observed in hydroprimed seeds and was associated with seed deterioration. The different responses in physiological and biochemical attributes induced by hydropriming were related fo their genotype and partially affected by fhe initial characferisfic differences befween fhe two maize lines causing different maize seed appearance.

“…The degradation was also related to the moisture content of the samples during storage. Samples with higher levels of moisture content degrade more rapidly than the lower levels of moisture content due to oxidation (Chiu et al 2003). Carbohydrate content decreased significantly (70%) in jute bags under ambient condition at the end of the storage period compare to initial value.…”

Influence of vacuum packaging on seed quality and mineral contents in chilli (Capsicum annuum L.)

Studies were carried out to find out the influence of vacuum packaging on physical parameters of whole chilli and biochemical constituents in chilli seeds. Chilli fruits were stored in vacuum packed and jute bags stored at room temperature (25±2°C), cold storage (4±1°C) under both light and dark conditions for a period of 24 months. At the end of the storage period, seeds were separated from fruits and various parameters viz., moisture content, capsaicin content, ascorbic acid, carbohydrates, protein and mineral elements like Fe, P, Na and K were analyzed. It was observed that the samples stored in vacuum packed bags maintained the quality with least deterioration in all the quality parameters compared to samples stored in jute bags.

“…Research on seed storage under non-refrigerated conditions suggests that seed moisture may be more important than temperature in determining longevity (Ellis, 1998). Exposure to ambient humidity can be effectively minimized by vacuum sealing, and even a partial vacuum has proven successful in extending seed longevity (Chiu et al ., 2003; Yeh et al ., 2005). This suggests that in conditions where refrigeration may not be feasible, vacuum sealing could offer a less energy-intensive solution.…”

Changes in seed viability over 12 months of low-input storage conditions were monitored on five diverse seed species grown in the tropics: amaranth (Amaranthus cruentus), lablab bean (Lablab purpureus), moringa (Moringa oleifera), pumpkin (Cucurbita moschata) and tomato (Solanum lycopersicum). Because the costs of maintaining lowtemperature storage can be prohibitively expensive in developing countries, this study explored alternatives to low-temperature storage at the Educational Concerns for Hunger Organization (ECHO) Asia Impact Center Seed Bank in Northern Thailand. Specifically, this research compared the effects of vacuum sealing and refrigeration on stored seed viability in both laboratory and field settings. While seed species was an influential factor in determining seed longevity, the relative importance of vacuum sealing and refrigeration differed for the dependent variables of seed moisture content, germination rate, mean time to 50% germination and field emergence. Although the combination of vacuum sealing and refrigeration was most effective at conserving seed quality as measured by each of these variables, the storage of seeds in vacuum-sealed packages at ambient temperatures was more effective than unsealed but refrigerated packets at conserving low moisture content and high germination and field emergence rates across species. This suggests that for resource-constrained seed banks in the tropics, vacuum sealing with or without refrigeration may represent a viable alternative to other expensive and energy-intensive storage techniques.
