互叶白千层不同无性系早期生长性状及综合评价
Early Growth Traits and Comprehensive Evaluation of Different Clones of Melaleuca alternifolia
摘要
Abstract
To screen out excellent clones of Melaleuca alternifolia suitable for popularization and cultivation in the Beibu Gulf region of Guangxi,10 superior clones of M.alternifolia were used as research objects.The differences in growth traits among different clones were analyzed,and cluster analysis and comprehensive evaluation were conducted on these growth traits.The results showed that there were significant differences in plant height,ground diameter,crown width,and preserva-tion rate among the 10 M.alternifolia clones;the correlations among various growth indicators were significant.Cluster anal-ysis could classify the 10 M.alternifolia clones into 2 groups.Principal component analysis extracted 2 principal components with a cumulative contribution rate of 90.65%.The comprehensive ranking of the growth performance of the 10 clones was as follows:B8>B1>B7>B6>B2>B3>B5>B9>B10>B4.Comprehensive nanolysis indicated that clones B8,B1,B7,and B6 performed excellently,with fast growth rates and preservation rates above 85%.Among them,clone B8 had the highest comprehensive score and was suitable for promotion as an excellent clone.关键词
