摘　　要：本文应用统计分析方法研究了 2 2个不同种源和 30 0个不同无性系青杨幼树的抗病特性 ,其结果表明 :2 2个不同种源间和 30 0个无性系间及个别种源的无性系间在 0 .0 1水平上有显著差异 ,有的种源感染两种病害都重 ,有的种源感染两种病害都轻 。This papar deals with the diseases resistance of young trees of Populus cathayana Rehd of 294 individual trees from 22 different provenances by the method of statistics analysis .The results show that there are significant variations in all provenances and clones and few clones of the same provenances at 0.01 level, some provenances have a high index of infection to two diseases, others have a low index of infection to two diseases ,some provenances have a high index of infection to one, at the same time, they have a low index of infection to another, however,others are contrary.
