摘要
以4个葡萄品种扦插苗为试材,采用盆栽试验的方法,研究了水分胁迫对葡萄叶片生理生化特性的影响,并结合隶属函数法对4个葡萄品种的抗旱性进行了综合评价。结果表明:随着水分胁迫程度的增加,葡萄叶片相对含水量和叶绿素含量都明显下降;叶片相对电导率、可溶性糖、脯氨酸的含量则明显增加;4个品种的抗旱性随土壤水分的不同而有异,中度水分胁迫时,抗旱性依次为:玫瑰香>红提>京秀>巨峰;严重水分胁迫时,抗旱性则为:玫瑰香>京秀>红提>巨峰。
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：Meiguixiang〉Hongti 〉Jingxiu〉Jufeng;It was Meiguixiang〉Jingxiu〉Hongti〉Jufeng under higher stress.
