本文分析了100个杉木家系在广东省6个试验点造林的生长表现情况,试验按照数理统计的要求设计,采用性状水平分析法(performace Lerel Analysis),对各试验林中各个家系的生长量作出标准得分估算,并应用最小湿著差异检验法和对照对比法,从各个水平进行综合分析。初步选择出20个优良家系,并提出了各个家系在广东省的特别适生区域,为建立优树无性系第1代种子园提供了依据。
In this paper, we analyzed the growth performance of 100 Chinese fir families in six experimental sites in Guangdong Province. The experiment was designed according to the requirements of mathematical statistics. The performace Lerel Analysis was used to make the growth of each family in each experimental forest Standard score estimation, and application of the minimum wetting difference test and control method, from all levels of a comprehensive analysis. A preliminary selection of 20 excellent families, and put forward the various families in the special suitable area for Guangdong Province, to provide the basis for the first generation of seed orchard superior tree clones.
