Through canonical discriminant analysis,all the sampled individual trees could be distinguished as two groups by frequency express of gene Aap-1d in Aap-1 loci,one group comprised the individuals with Aap-1d gene, the other with no Aap-1d.

• 典型判别分析进一步证实不同生长势水平个体间Aap－1位点Aap－1d基因频率有极显著性差异，并基本上划分为二个类群。
