Response and Drought Resistance of Four Grape Varieties to Water Stress

Using 4 different grape varieties as experiment material,the effect of water stress on physiological and biochemical characteristics was studied,and the drought resistance of different grape varieties was comprehensively evaluated by subordinate function.The result showed: with the increasing of water stress,leave relative water content and chlonophy content of grape leaves were decreased,and the leaf membrane conductions,soluble sugar content and proline content were increased.The drought resistance of grape varieties was different.When the soil water stress was comparatively low,their drought resistance could be ranked as follows:MeiguixiangHongtiJingxiuJufeng;It was MeiguixiangJingxiuHongtiJufeng under higher stress.
