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。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.
