| 摘 要： | 采用大样本调查方法,以预选优株为调查中心,分别连续调查优株所在样地内5年生钟萼木幼树个体树高、地径的生长性状,应用数理统计进行归类分析。结果表明,多年生幼树群体的树高、地径生长表型分化遵循正态分布,利用"t"检验选择法确定优株筛选的选择标准,应用所确定的选择标准筛选速生优株,共筛选优良单株2株,5年生优株与优株所在群体比较,树高和地径分别增长115.8%、82.9%和251.9%、103.7%。

| Abstract: | The height and rooting-diameter growth characteristics of the 5-year sapling of Bretschneidera sinensis were investigated respectively in the standard sample spot of elite-trees by large sample method,with the primarily selected dominant trees as investigation center.The height and rooting-diameter growth characteristics were both classified and analyzed by mathematical statistics.The result indicated that the growth phenotypic differentiation of height and rooting-diameter in sapling colony of Bretschneide... |
