| Abstract: |
| Studies on the physiological and biochemical changes of Caragana microphlla Lam. and Caragana korshinskii Kom, seeds were carried out using the methods of high temperature and high humidity (40℃,100%RH) accelerating aging. The results showed that the best time grades of high temperature and high humidity artificial aging means is 0 h, 8 h, 16 h, 24 h, 36 h and 48 h; the seed germination percentage and germination index descended (P<0.05）with seed aging. ACP activity, a sensitive index of seed quality, decreased with seed aging（P<0.05）. Leaching of sugar increased with seed aging, and lipid peroxidation was an important reason for seed deterioration. |
