| 摘 要： | 对黄壤和喀斯特土壤两种土壤类型的森林内部和林窗中蝴蝶花的生长指标进行调查,研究异质生境下蝴蝶花的克隆可塑性.结果表明:蝴蝶花在黄壤生境中的分株高度、分株基径和根茎直径均高于喀斯特土壤生境,而分株密度低于喀斯特土壤生境.光照显著影响分株密度,在同一光照条件下土壤质地对分株密度没有显著影响.喀斯特森林内部蝴蝶花的花蕾数及开花数为0,这可能解释为光照和土壤质地双重压力下蝴蝶花对资源摄取和能量分配的权衡与生长维持.在一定程度上,蝴蝶花在黄壤生境中通过增强单个分株的竞争力、减少个体数量来适应环境,趋向K对策,在喀斯特生境中则通过增加个体数量、维持分株竞争力来适应环境,趋向r对策. |

| Abstract: | An investigation was made on the growth indices of Iris japonica growing on the yellow soil and Karst soil within a subtropical evergreen broad-leaved forest and in the forest gaps,aimed to approach the clonal plasticity of I.japonica in heterogeneous habitats.The results showed that the ramet height and diameter and the rhizome diameter of I.japonica were significantly higher in yellow soil habitat than in Karst soil habitat,while the individual density was in adverse.Light had significant effects on rhizo... |
