| 摘 要： | 玉树和燕子掌非常相似,通过对一株开花“玉树”与典型燕子掌、玉树形态特征、染色体的研究对比,阐明正确区分玉树与燕子掌的方法.分类要以最适条件下培养的正常叶为依据,选择其典型特征如叶的形状、基部是否贯穿等,还需以染色体为依据作辅助判断.

| Abstract: | There are some similar aspects between Crassula perforate and Crassula argentea.Through the comparison of a blooming Crassula perforate with a typical Crassula argentea in form and chromosome,we find a proper way to differentiate them.The classification is based on the leaves grown in the most suitable conditions,with their specific characteristics such as the shape of the leaves and the linking-up of leaves at the base.Chromosome serves as an assisting determining factor. |
