Impact of Temperature &; Relative Humidity on Seed of Pongamia Pinnata : Pongamia pinnata: Role of temperature and relative humidity on Seed longevity

Pongamia pinnata is an important minor non-edible oilseed tree. This tree is valued not only for its oil but also for its nitrogen fixing ability, reclamation of degraded land and soil erosion restriction capabilities. So, the Conservation of this wonderful crop is essential and seed is the most common and economical method of conservation. Seed storage problems are most common in tropical countries like India, because of predominance of hot and humid tropical and subtropical climate with great variations in temperature, rainfall and relative humidity across the year. So, this study involves investigation of affect of various storage conditions on seed viability to get useful information regarding the relative contribution of these factors to loss of seed viability and vigour during storage. The study provides in depth analysis of various biochemical changes take place during storage of Pongamia pinnata seeds.
