油茶(Camellia oleifera Abel)是我国特有的食用油料树种,面积达6000多万亩。由于油茶异花授粉的特性,种内变异极其丰富,单株产量差异很大。随着油茶生产和科研的深入进行,以良种为主要技术措施的低产林改造途径正日趋受到重视。 本文在连续十几年对油茶树体性状和单株产量观察的基础上,采用通径分析,聚类分析等统计方法,探讨油茶树体性状与单株 Camellia oleifera Abel is a unique edible oil tree species in China, with an area of ​​more than 6000 mu. Due to the characteristic of cross-pollination of Camellia oleifera, intra-species variation is extremely rich, and the yield per plant is very different. With the further development of Camellia oleifera production and scientific research, the ways of transformation of low-yield forests with improved varieties as the main technical measures are increasingly being taken seriously. Based on the observation of tree traits and single plant yield in Camellia oleifera for more than 10 consecutive years, the statistical methods of path analysis and cluster analysis were used to investigate the relationship between the traits of Camellia oleifera and single plant
