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。
In order to determine the drought resistance ability of different olive cultivars, the contents of proline, relative conductivity, bound water / ethanol in leaves of seven olive cultivars introduced to Albania, Italy, Spain and Greece in the late dry season and late rainy season, Free water, relative water content and malondialdehyde content and other physiological indicators measured, and the use of spss data analysis of the measurement results, and finally fuzzy membership function evaluation. The results showed that: (1) There was no significant difference between drought resistance and geographical provenance in olive cultivars; (2) Among the seven olive cultivars with different provenances, the highest drought resistance was peguer, with a membership function of 0.647 The weakest is the fruit of soybean, the membership function is 0.208, and the order of drought resistance from strong to weak is Corgi> Peguer> Bella> Carlin> Buddha> Colati.
