摘要:文章对红锥中心分布区的广东、广西、福建主要种源进行早期生长比较试验。结果表明:中心分布区种源在广州龙洞地区生长差异明显,2年生时最优种源的排序是来自广西大青山、广东高州、广西容县、广东信宜、广东陆河。选择优良单株采种的效果明显优于普通混合采种,表型选优的材积平均生长增益达297.8%以上,各种源的早晚相关性均达到极显著水平,良种的区域性选择十分必要。
The growth performance at early stage of main provenances from the central area of Castanopsis hystrix natural distribution, Guangdong, Guangxi and Fujian province, have been compared in Guangzhou. The declined order of their growth are as follows, Daqinshan (Guangxi) , Gaozhou (Guangdong) , Rongxian (Guangxi) , Xinyi (Guangdong) and Lehe (Guangdong) provenances. Seed collection from plus tree is obviously better and that from general stand. The average growth gains for plus tree is up to 297.8%. There is significant relation between first year growth and next few years. Good benefits can he captured from provenances selection.
