Review on: Effect of Seed Storage Period and Storage Environment on Seed Quality

Abstract

Seed quality deterioration is inevitable process. Since seed is a vital input in agriculture which determines not just the production but also the productivity, it is crucial to maintain the seed quality as well as seed vigor during the storage. Storage is a basic practice in the control of the physiological quality of the seed and is a method through which the viability of the seeds can be preserved and their vigor kept at a reasonable level during the time between planting and harvesting. Many researches on seed storage period have been investigated that seeds can be stored for short period is found in least deterioration. In contrast changes associated with seed deterioration are depletion in food reserve, increased enzyme activity, increased fat acidity and membrane permeability. As the catabolic changes continue with increasing age, the ability of the seed to germinate is reduced. Gradual decrease in the seed quality parameters were observed, as the storage period increase. It is estimated that good quality seeds of improved varieties alone can contribute about 18 to 20 per cent increase in crop yield keeping all the other inputs constant. Lastly using seeds as planting material which stored with in short period of time and in proper environment is very important.

Garden, greenhouse or climate chamber? Experimental conditions influence whether genetic differences are phenotypically expressed

“…Thus, we cannot know whether there were detectable parental effects in the first place. Theoretically, long-term storage of seeds may cause carry-over effects into the F1-generation in suboptimal storage conditions, with resurrected plants having lower fitness due to the storage and producing lower quality seeds (Gebeyehu, 2020). The seed material used in this study was stored at –20°C after drying at 15% RH which are optimal conditions to ensure viability for several decades (Solberg et al, 2020).…”

Relationship of Improving Triticale Stored Seed Field Emergence by α-Amylase Enzyme on some Growth Characteristic and Biological Yield

“…Prolonging the storage period leads to an increase in the activity level in the embryo and the consumption of food stored in the endosperm of the stored seeds, which causes energy consumption in these processes and negatively affects the viability of the seeds and emerging seedlings' vigour, which in turn weakens the ability of the seedlings to elongate and emerge outside the soil [11]. The decreases in the emergence of seedlings reflect the variation in seed vigour and its ability to germinate and the growth of root and shoot systems up to the emergence.…”

GAMMA IRRADIATION INDUCED CLASTOGENIC ABNORMALITIES IN Vigna radiata

“…The long post-irradiation storage time may deteriorate the quality of V. radiata seeds which are associated with reduced food reserve, enhanced enzyme activity, increased fat acidity, and membrane permeability, which then reduced seed germination (Gebeyehu, 2020). Post-irradiation storage of onion (Allium cepa) seeds for 24 hr significantly increased the percentage of abnormal seedlings and reduced root and seedling lengths but not the germination activity (Amjad & Anjum, 2003).…”
