| Abstract: | The germination test of 16 Anhui wheat varieties was conducted under stress of water deficitency.The experimental results showed that the seed germination percentage,cloeoptile length,plant height,root length,dry matter weight per plant,root vitality and water loss rate of excised leaf of all varieties decreased,and while the proline content increased.There were siginficant differences among 16 varieties.The drought stress resistance of 16 wheat varieties was comprehensively evaluated by the method of grey comection analysis.Wan 38,Wan39 and Wan19 had stronger drought resistance in germination and seedling stage. |
