摘要: 以12 个早实核桃品种苗木为试材,采用自然干旱胁迫及复水的方法,测定了复水后各品种
与抗旱性有关的生长指标、生理生化指标、光合指标及叶绿素荧光指标。对复水后各指标进行主成分分
析,筛选出影响抗旱性的5 个主要指标,利用隶属函数对早实核桃品种的抗旱性进行了综合评价。结果
表明:12 个早实核桃品种抗旱性强弱依次为:辽核1 号 > 中林5 号 > 新早丰 > 温185 > 鲁光 > 中林
1 号 > 辽核4 号 > 扎343 > 强特勒 > 香玲 > 西林2 号 > 西扶1 号。此评价结果与大田试验结果基本
一致。

Abstract: The seedlings of 12 early fruiting walnut cultivars were used as the test materials in this
study to determinate drought resistance index such as physiological and biochemical index,photosynthesis
and chlorophyll fluorescence parameters by using natural drought stress and after rewatering method. Then
5 major indicators were selected by using principal component analysis to analyze drought resistance
coefficient of each drought resistance index characters. And then the drought resistance of early fruiting
walnut varieties were comprehensively evaluated by using membership function. The sequence of drought
resistance of twelve early fruiting walnut cultivars were:Liaohe 1 > Zhonglin 5 > Xinzaofeng > Wen 185 >
Luguang > Zhonglin 1 > Liaohe 4 > Za 343 > Chandler > Xiangling > Xilin 2 > Xifu 1. The evaluation
result is similar to the reaults tested in the field.

Key words: walnut, early fruiting, soil drought stress, multiple statistics analysis, drought resistant compehensive evaluation
