摘要
采用随机区组设计 ,对华北落叶松无性系种园 2 0个无性系子代的形质指标和实生苗高度进行了测定 ,通过方差分析和布雷金评价结果表明 ,2 0个子代所测性状均明显高于一般林分子代 .
Seed indexes of form-quality and height s of seedlings were measured, based on the random block design with progenies of 20 clones from a 28 year-old seed orchard of Larix prinnipis-rupprechtii. ANOVA and Breckin Evaluation system were used to analyse the data obtained. The result showed that the indexes measured from 20 clones were significantly highe r than those in general stardards.
