Influence of storage period on the quality indicators of Astragalus falcatus Lam. seed

Seed storage is the final stage of technological process its production, purpose which to ensure preservation seed quality from collection use. At same time, loss seeds in sowing conditions can cause significant losses both direct subjects production medicinal crops and producers raw materials. questions regarding terms sickle-leaved astragalus (Astragalus falcatus Lam.) rates their during remain insufficiently defined. The aim our research was establish objective with maximum qualities. conducted for nine years. It found that surface gloss a stable feature astragalus, not lost storage, while color relatively unstable feature. During first two years, no noticeable changes were noted. more than 9 gradually acquired uniform reddish-brown greenish-yellow. rate determined. Freshly collected characterized by germination hard rate, respectively — 84 14%. energy 72%. highest few second year 78%. content decreased 10%, 83%. Therefore, effect on indicator clearly observed, 7% lower immediately after harvesting finishing compared storage. four years only 21%, indicates gradual loss. general regularity decrease also gradual. Starting fifth studied sample began rapidly lose Its similarity ninth 3%. completely five determined economic durability at least biological lasts
