| 摘 要： | 通过对幼龄楸树无性系生长、生理和形态性状的遗传变异分析,探讨楸树早期选择指标,并进行楸树优良无性系的选择.结果表明:1年生楸树无性系间树高存在显著差异,地径不存在差异,而2～4年生楸树无性系间树高、胸径均存在极显著差异.2年生叶部各性状无性系间均存在极显著的差异,3年生皮孔各性状无性系间均存在极显著的差异.3年生树高、...

| Abstract: | Early selection indexes of growth,physiological and morphological traits of Catalpa bungei C.A.Mey were discussed and excellent clones were selected.A significant difference in seedling height and no significant difference in ground diameter were observed between one-year-old clones,while highly significant differences in seedling height and diameter of breast-height(DBH) were found between two-to four-year-old clones.There were extremely significant differences in leaf characters between two-year-old clone... |
