摘　　要： 选择中华猕猴桃与美味猕猴桃共７个品种，对耐旱性的形态与生理指标进行了分析测定。结果表明：与耐旱性较弱的品种相比，耐旱性较强的品种有较大的叶片厚度、上表皮细胞厚度、栅栏组织厚度；栅栏组织／海绵组织比较高，气孔密度较大，束缚水／自由水比例较高，表明品种耐旱性较强；干旱条件下，耐旱性较强的品种叶片游离脯氨酸累积率较高。 The morphological and physiological index of drought resistance were measured and analysed with 7 ki-wifruit cultivars [A. chinensis Planch,and A. delieiosa (A. chev.)C. F. Liang et A. R. Ferguson] .The resultsshowed that the leaf thickness,palisade tissue thickness,palisade tissue/spongy tissue ratio,stomato densityof the cultivars having higher drought resistance were higher and the bound water content/free water contentratio was higher as well;The leaf free proline inerease was higher in cultivars with stronger drought resis-tance than in those with weaker drought resistance under water deficit condition.
