| 摘 要： | 2006年在广西3个试验点对收集于广西、广东、湖南、福建及海南的9个大叶栎种源进行优良种源选择试验,结果表明:(1)种源间树高、胸径和材积生长均达极显著水平。(2)初步选出两个优良种源,即广西融水种源(ZY5)和广西苍梧种源(ZY7)。该两个优良种源与最差种源海南乐东种源(ZY6)比较,平均树高增加27.80%～29.47%,平均胸径增加29.97%～31.86%,单株材积增加119.32%～123.47%;与种源总体平均数比较,平均树高增加8.12%～9.53%,平均胸径增加6.91%～8.46%,单株材积增加20.24%～22.52%。

| Abstract: | The experiment in regard to selection of superior provenances of Castanopsis fissa was carried out in 3 plots in Guangxi province in 2006.These provenances consisted of 9 origins from Guangxi,Guangdong,Hunan,Fujian and Hainan Provinces.It showed that(1) the variation of tree height,DBH(diameter at breast) and volume of wood increment were significant among the provenances;(2) two superior provenances were selected,which were ZY5 and ZY7,both from Rongshui and Cangwu of Guangxi Province.Compared to worst per... |
