摘要
用带状测树器对南亚热带气候条件下生长的落叶树柚木（Ｔｅｃｔｏｎａ ｇｒａｎｄｉｓ Ｌ．ｆ．）、喜树（Ｃａｍｐｔｏｔｈｅｃａ ａｃｕｍ ｉｎａｔａＤｅｃｎｅ）和常绿树火烧花（Ｍａｙｏｄｅｎｄｒｏｎ ｉｇｅｕｍ Ｋｕｒｚ）１６年生（测定开始时年龄）的立木的径向生长进行了６ａ 的测定。研究结果表明，所测立木的年均胸围生长量在１．５～２．５ｃｍ （胸径生长量为０．４８～０．８０ｃｍ ）之间，年间有一定的差异。年生长量与年积温及与年降雨量均无明显的相关。胸径生长呈现较明显的和降雨量及气温相同的季节节律，但降雨量和生长的相关性更大些。不同种胸径生长的季节节律对气温和降雨量变化的反应有差异。
The growth at GBH of 8 trees of Tectona grandis L.f., Camptotheca acuminata Decne and Mayodendronigeum Kurz were measured for six years with dendrometers. Mean annual growth at GBH was between 1 5cm and 2 5cm, with the most growth from June to Augast. The annual growth was not significantly correlated with the sum of temperature and sum of rainfall in a year. Growth at GBH of the trees showed similar monthly patterns to that of rainfall and temperature. The mean daily growth was more significantly correlated with the mean daily rainfall than mean temperature. It was found that the response to rainfall and temperature was different among the species.
