摘要
利用盆栽试验通过观察叶片运动形式，测定叶片解剖结构、与植物搞旱性密切相关的生理生化指标，对青石山区主要经济林树种香椿、核桃、杏树、桃树的抗旱特性进行了研究，用模糊数学隶属函数法进行综合评判，找出了供试树种的抗旱性的差异，并运用主成分回归分析找出可用于抗旱性测定的指标。
Drought resistance of four major economic fruit tree species, including Toona, Walnut,Apricot and Peach, were tested on the Potted individuals. The results by fuzzy comprehensive appraisal analysis indicate that the dopes of drought resistance are different among those four economic be species; by the main components regression analysis, good indexes that can be used to re search plant drought resistance were got.
