柚木(Tectona grandis L.f.)是热带地区的主要商品材造林树种。在我国有较大面积的引种栽培,除台湾省(约有柚木人工林4.5万亩)外,主要分布于广东、云南,福建、广西有少量分布。我们先后对广东、云南3千亩左右的柚木人工林进行了金面的选种调查,选出优树85株。从1975年起开始分批进行柚木子代鉴定工作。本文仅对鉴定工作中的部分指标进行分析,力求对现行的选树方法做出评价,做为改进选树方法的依据。同时对各家系子代的优劣作出初步鉴定。
Teak (Tectona grandis L.f.) is the dominant tree species in the tropics. In our country, there is a large area of introduction and cultivation, except for Taiwan Province (about 45000 mu of teak plantation), mainly distributed in Guangdong, Yunnan, Fujian, Guangxi, a small amount of distribution. We successively carried out the gold seed selection survey on teak plantations of about 3 acres in Guangdong and Yunnan Provinces, and selected 85 elite trees. From 1975 onwards teak appraisal work in batches. In this paper, only part of the identification of indicators in the analysis, and strive to make an assessment of the current tree selection method, as a basis for improving the method of tree selection. At the same time the pros and cons of each family’s offspring to make a preliminary identification.
