| 摘 要： | 研究了分布于开阔地和辽东栎林下短柄五加无性系种群拆散方式、无性系的形态可塑性和分株的死亡年龄，研究结果表明，开阔地上无性系分株的扩散方式为稀疏线型，根茎长度、无性系分株数目，林下和开阔地差异显著，根茎分枝角度、无性系根茎总长无显著性差异。林下分株的死亡年龄显著小于开阔地上无性系分株的死亡年龄。 |
| 关 键 词： | 短柄五加 无性系种群 分株 形态可塑性 栎林下 开阔地 |

| Abstract: | Acanthopanax branchypus is a species of endangered plant peculiar to China,only distributing in loess plateau.Diffusion pattern and morphological plasticity of A.branchypus clone and ages of ramet were investigated in the natural distribution region in southern Nanniwan town,Yan 'an City,Shaanxi Province.10 plots were randomly set in two habitats of open land and Quercus liaotungensis forest.Each plot area was 5×5 m\+2,on the basis of previous observation of the maximum rhizome length.Detailed inf... |
