采用 SRAP标记对来自山东徂徕山、泰山、崂山、蒙山的71份刺楸种质进行遗传多样性分析.结果表明：12对引物共扩增出110条带,其中102条显示多态性,多态位点百分率(PPL)为92.73%；71份刺楸种质的遗传相似系数(GS)0.573~0.975,平均0.822,说明各种质间具有较高的遗传变异；种群间遗传分化系数(GST )为0.1360,表明有13.6%的变异存在于种群间,86.4%的变异存在于种群内,种群内的遗传分化显著大于种群间的遗传分化.UPGMA聚类表明71份种质在相似系数为0.71时可以聚为3类,总体上来源相同的种质优先聚类,但也存在交叉聚类.

The genetic diversity of Kalopanax septemlobus from Shandong was investigated by using SRAP marker.The results showed that 1 10 bands were amplified by 12 pairs of informative and reliable primers,of which 102 were polymorphic,resulting in a polymorphic rate of 92.73%.GS values of 71 K . septemlobus materials were 0.573~0.975,whose average was 0.822.There was higher genetic diversity a-mong all the materials.The genetic differentiation coefficient in populations was 0.136,there were vari-ances of 13.6% in populations,86.4% genetic variation existed within populations.This data illustrated genetic variation within population was larger than that among populations.UPGMA cluster analysis showed that 71 materials were classified into 3 groups when the similarity coefficient was 0.71.Overall, materials from the same source mostly clustered together,but cross clustering was also exist.Finally,we discussed the cause of the endangerment status K .septemlobus and proposed some management strategies for effectively protecting the species.
