对海南50个不同油茶优良单株的果实和大陆油茶‘华金’(对照)的果实经济性状指标进行测定,并采用SPSS19.0软件对其进行主成分分析.结果表明:各优株及其对照的果实经济性状的变异程度显著不同,变异系数6.73%~46.92%;用主成分抽提出5个特征值>1的主成分,累积贡献率为81.844%;二维排序图揭示了不同优良单株前3个主成分(油品质因子、果实大小因子和出籽率因子)的分布情况;50份海南油茶果实经济性状综合评价排名前10位分别为:TCPX-7、CMJL-6、QZWL-3、CMJL-4、QZCZ-3、QZCZ-4、CMZX-1、TCPX-3、QZWL-2和TCNK-1,而对照‘华金’排名21名.本研究找出了海南油茶果实经济性状评价的5个主成分,揭示了海南油...

To establish a comprehensive approach to evaluate economic character of Hainan Camellia oleifero, Data on 16 fruit eco-nomic characters for 50 species of Hainan Camellia oleifero and Hunan ‘Huajin’ ( control) were determined and then were under-taken principal component analysis by SPSS 19.0 software. Descriptive statistics showed that the premium species varied significantly from the control group, with coefficient of variation ranging from 6.73% to 46.92%. Five principal components (eigenvalue>1), with cumulative contribution rate adding up...
