摘　　要：In order to study olive’s drought resistance in Yunnan province, different varieties of olive trees from Albania, Italy, Spain and Greece were cultured, and leaves from these trees in drought season and rainy season were col ected and determined by physiological indices, such as proline content, relative electric con-ductivity, binding water/free water, relative water content and malon-dialdehyde in leaves. The evaluation of drought resistance with subordinate function showed that：There were no significant differences among drought resistances of varieties and provenances. The change of physiological indices in different varieties showed differ-ent ranges. The drought resistance of seven varieties decreased in order as fol ows：Koroneiki〉 Picual〉 Berat〉 Kaliniot〉 Frantoio〉 Coratina〉 Arbequina.为确定不同种源油橄榄品种的抗旱能力,分别在旱季末期和雨季末期对阿尔巴尼亚、意大利、西班牙和希腊4个地区引种的7个油橄榄品种叶片中的脯氨酸含量、相对电导率、束缚水/自由水、相对含水量和丙二醛含量等生理指标进行测定,并运用spss对测定结果进行数据分析,最后采用模糊隶属函数进行评价。结果表明:(1)油橄榄品种间的抗旱性与地理种源没有明显的差异性;(2)7个不同种源的油橄榄品种中,抗旱性最强的是皮瓜尔,隶属函数均值为0.647最弱的是豆果、隶属函数均值为0.208,抗旱性由强至弱依次为柯基>皮瓜尔>贝拉>卡林>佛奥>科拉蒂豆果。
