不同光照环境对秃疮花表型多样性的影响

Effects of Different Light Environment on Phenotypic Diversity of Dicranostigma leptopodum

摘要: 通过对比分析2种光照环境条件下的秃疮花表型特征，来探讨不同光照环境条件对秃疮花表型多样性的影响。结果表明：秃疮花种内存在较为丰富的表型多样性；全光照环境条件下的秃疮花表现为一定的徒长态势，观赏效果不佳；强光照环境（100%光照）容易导致秃疮花的基生叶和茎长度的显著增加；适当遮荫环境（60%光照）有利于秃疮花的茎分枝数量（花朵数量）、花瓣大小、基生叶数量和盖度等观赏特征指标的增加。

Abstract: We compared the phenotypic characteristics of Dicranostigma leptopodum under 2 light environment to explore the effects of different light habitat conditions on the phenotypic diversity of D. leptopodum. The results showed that there was abundant intraspecific diversity of D. leptopodum; full light environment result in a situation of spindling, and the viewing effect is not ideal; the condition of high light(100% light conditions) tends to result in a significant increase in the length of the basal leaves and stems of D. leptopodum; suitable shade environment(60% light conditions) could increase the number of stem branches(number of flowers), the size of petals, the number of basal leaves and the coverage of D. leptopodum.
