油茶干籽含油率及主要经济性状相关性分析

Correlation analysis of oil rate of dry seed and main economic characters in Camellia oleifera Abel

以湖北省25个油茶无性系为研究对象,对不同无性系干籽含油率及其主要经济性状的相关性进行了研究。结果表明,油茶的干籽含油率为17.4%～39.2%,各无性系之间差异较大,不同产地油茶干籽含油率存在显著差异;油茶的主要经济性状与干籽含油率的相关性由大到小依次为种仁含油率、干籽出仁率、单株产量、冠幅、每平方米冠幅产量、种仁含水率。

Taking 25 clones of Camellia oleifera of Hubei Province as research objects,oil rate of dry seed and its correlation with the main economic characters were studies.The results showed that oil rates of dry seed ranged from 17.4% to 39.2%,and there were significant differences among different clones and different sites.The order of correlation between oil rate of dry seed and main economy characters in C.oleifera from high to low was： oil rate of kernel,kernel percent of dry seed,yield per plant,crown width,yield per m2 crown and water rate of kernel.
