摘要
从杉木全国优良家系区域试验中 ,选取安徽黄山、广西融安、广东信宜、江西分宜、福建洋口等 5个试验点 ,测定了其10年生树高、胸径、材积和木材密度 ,分析了杉木木材密度及生长基因型×环境交互作用规律。多点联合分析表明 ,木材密度、胸径、材积性状家系间存在着显著或极显著差异 ,并且家系与地点的交互作用达到显著水平。通过Francis -Kannen berg模型对木材密度和材积的遗传稳定性进行了分析。并在此基础上 。
The height,dbh,volume and wood density of 10 year old Cunninghamia lanceolata were tested on the 5 experimental points of Huangshan,Rongan,Xinyi,Fenyi and Yangkou.This paper analyses the C.lanceolata wood densities and the growth genotype × environment interaction law.The many point combination analysis shows that wood densities,dbh and volume characters exist significant or extremely significant differences between families,and furthermore,the interaction between families and points reaches the signifi...
