摘要：研究了红锥天然分布区各种源的主要特性,从总体看可划分为3大类,来自水热充沛地区的种源(21.1℃)具有嫁接植株生长快、形成花蕾和开花时间较早,展枝展叶早,叶片短小、枝叶数量多等特性;来自年均温低或较低(<19.9℃)的其余两类种源则嫁接植株生长较慢,物候较迟,叶片较宽大。从全分布区嫁接植株的生长变异看,其变异属随机变异,天然分布中种源的生长变异大于种源内的单株变异,种源选择基础上进一步进行单株选择是一种理想的生长改良途径。
Studies on provenances properties of Castanopsis hystrix at different natural distributions showed that it could be divided into 3 groups. The provenance from warm and rainy area （ 21.1℃ mean annual temperature ） had faster growth of grafted plants with smaller leaves, earlier development of flower, branches and leaves, The other two provenances from cool area with average annual temperature below 19.9℃ grew slowly with larger leaves, later development of flower, new branches and new leaves. Random variation was the main model for growth variation of C. hystrix in term of grafted plants at natural distribution. The variation among provenances on growth was much larger than that within provenances. Single plant selection besides provenance selection was a good way to improve the growth.
