摘　　要：以4个不同品种为砧木的油茶嫁接苗为试材,对不同砧木油茶嫁接苗的嫁接亲和性的10个指标进行了测定,利用主成分及隶属函数分析法对其嫁接亲和性进行综合评价。结果表明:10个亲和性指标应用主成分分析归纳成3个主成分,前3个主成分的累计贡献率为100%;主成分分析的综合评价结果与隶属函数分析结果一致,4个不同砧木品种嫁接亲和力由强到弱排序为:赤霞>秋霞>朝霞>晚霞。Ten grafting affinity related indexes of grafting seedlings with four different varieties as stocks was studied,and grafting affinity was evaluated by principal components analysis and subordinate function analysis.Results show that the ten grafting affinity related indexes could be classified into 4 component parts,and the cumulative contribution proportion of the former three principal components was 100%;comprehensive evaluation result of principal components analysis and was consistent with that of subordinate function analysis,and the grafting affinity of the four stock varieties is gauged as follows：Chixia 〉 Qiuxia 〉 Zhaoxia 〉 Wanxia.
