Effect of mid-storage invigoration treatments on biochemical activity ofenzyme associated with seed quality of paddy under ambient storageconditions

Mid-storage invigoration treatments improve the physiological condition of the seed and increase storability of the treatedseeds. This investigation was performed to assess the biochemical alterations in seed quality of treated seeds stored underambient condition. The seed quality parameters such as dehydrogenase, alpha-amylase and protease were assessed inthese stored seeds at monthly intervals. There were significant differences among the seed treatments with respect to thebiochemical enzyme activities as the age and storage period increased.The enzymes which help to maintain the quality andstorability of seeds viz. dehydrogenase, alpha-amylase and protease were maximum in the seeds treated with neem oil,hydration dehydration and red chilli powder.These treatments outperformed all other treatments in enhancing seed quality,under ambient condition. Therefore the cost effective and ecofriendly mid-storage invigoration treatments provide advantageto the farmers for prolonging paddy seed storage without compromising seed quality.
