摘      要：In order to investigate the change rule of rice seed germination rate dur-ing the storage, the effects of moisture content and storage temperature on Lianjing 7 rice seed germination rate were investigated. The 3×3 factorial design was adopt-ed. The test data was analyzed using SPSS. The results showed that after the Lianjing 7 rice seeds with moisture content of 14.5% were stored at 25 ℃ for 180 d, the germination rate stil reached 89%; after the rice seeds with moisture content of 11.5% were stored at 5 ℃ for 180 d, the germination rate was up to 96.6%; the rice seed germination rate was decreased gradual y with the prolonging of storage time; the moisture content and storage temperature were two key factors affecting the Lianjing 7 rice seed germination rate, and there was significant interaction be-tween moisture content and storage temperature.
