摘　　要：以6种花椒砧木1年生幼苗为试验材料,通过盆栽试验,测定不同干旱胁迫下花椒砧木的生长量、质膜透性、叶片相对含水量以及植株受害情况,采用隶属函数法对6种砧木的抗旱性进行了综合评价。结果表明:川植-3在整个干旱胁迫过程中表现出较小的生长量变化和叶片相对含水量变化,质膜透性变化不大,旱害症状轻等特征,抗旱能力显著优于其他备选材料。In this paper,six primary selected one-year-old seedlings of Zanthoxylum L.were selected as experimental material,and the growth rate,plasma membrane permeability,relative water content of leaves and damage of plants of the root stocks under different drought treatments were measured by pot experiment.The drought resistance of the six rootstocks was comprehensively evaluated by membership function method.The results showed that:Chuan Zhi-3,a wild material of Zanthoxylum L.,showed relatively little changes in growth and relative water content of leaves,little change in plasma membrane permeability,and mild drought symptoms duting the whole drought stress process,indicating that its drought resistance was significantly better than other candidate materials.
