Comparison on Seed Vigor of Different Ear Position Seeds in Wheat Varieties(Lines)
摘要
Abstract
[Objective]The better methods for the determination of seed vigor were selected in wheat. The seed vigor of different ear parts were explored in different wheat varieties. [Method]In this study, 5 wheat varieties or lines seeds of Wanmai33, Wanmai48, Yannong19, Yangmai158 and W1032(waxy wheat) were selected as the materials, all wheat varieties were set to four different treatments, including the upper ear position, middle & lower ear position and the whole ear position (CK). The seed vigor were comprehensively evaluated through such methods including the test of seed size, seedling growth, accelerated aging, cold soak, conductivity and simulated field germination rate determination, and also through the determination of SOD,POD, LOX,CAT and ADH activity, et al, and made correlation analysis among the main vigor indicators of the whole ear position (CK) as well as the comparison of average value of the seed vigor indexes in different ear parts of five wheat varieties.[Result]The determination of seedling growth and accelerated aging test, as well as five kinds of enzyme activity indexeswas significantly correlated with simulation field emergence. Seed vitality of different part spike wheat varietiesexisted obvious difference.[Conclusion]The test of the seedling growth, accelerated aging and the determination of five kinds of enzyme above were all better test methods for wheat vigor testing.The middle ear of wheat seed vigor was higher, the next was lower ear seeds vigor, upper ear seeds vigor was lower.关键词
