Seed reserves and nutritional quality slideshare- Storability of seeds is mainly a genetically regulated character and is influenced by quality of the seed at the time of storage, prestorage history of seed (environmental factors during pre and postharvest stages), moisture content of seed or ambient relative humidity, temperature of storage environment, duration of storage and biotic agents (Shelar et al, 08;The quality of raw tree nuts and oil seeds during storage and handling prior to processing has to be maintained Raw material entering the processing line with impaired quality will be especially susceptible to increased quality loss over the various processing steps and subsequent storage (Hadorn and Zürcher, 1977)
