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.
