Comparative Research on the Testing Methods of Different Seed Vigor in Rice
摘要
Abstract
[Purpose]The aim of this study was to find one or more inexpensive, uncomplicated, rapid, objective, reproducible, and related to field emergence for rice seeds vigor testing methods.[Method]In this study, 8 different type rice varieties as experiment materials, the following tests were used which containing: standard germination test, seedling growth test (the root length and shoot length of 7, 10, 14 days were measured at 25 ℃ and 30 ℃, respectively), radicle emergence test (25 ℃ and 30 ℃), accelerated aging test, cold treatment test and field emergence test. [Results]The results of correlation analysis between tests showed that the first cold treatment test, radicle emergence test of 25 ℃ at 96 h (r=0.942) and 30 ℃ at 66 h (r=0.876), and 25 ℃ seedling growth test on the 10 d of shoot length (r=?0.848) and on the 7 d of the shoot length (r=?0.902) were extremely significantly correlated with field emergence. Secondly, the cold treatment test and radicle emergence test of 25 ℃ at 96 h (r=0.913) was extremely significant correlation, and radicle emergence test of 30 ℃ at 66 h (r=0.876) was significantly correlated. The radicle emergence test between 25 ℃ by 96 h count and30 ℃ by 66 h count was extremely significant correlation (r=0.872). [Conclusion]In view of the above results, cold treatment test, the radicle emergence test (25 ℃ by 96 h and 30 ℃ by 66 h count) should be recommendation for a vigor testing methods in rice seeds.关键词
