摘要:: 以采集自国内外多个地区的浮萍种群样本为试材，采用形态分类、显微镜观察等方法，通过叶片大小、叶脉、根数目、叶背颜色、根鞘、根尖等指标对采集样本进行了系统分类鉴定，并对样本染色体数目进行研究。结果表明：浮萍基因组较小，染色体变异较多，且染色体数目变异较大，从2n=20、30、40、60不等。该试验建立了简便的形态学分类系统，为浮萍的分类和细胞学研究提供了依据。

Abstract:: Taking duckweed populations collected from some countries and regions as materials,using morphological classification,microscope observation method,the samples were identified through observeation of size and vein of leaf,numbers of root,color of back of leaf,root sheath and root tip,number of chromosome was observated.The results showed that duckweed genome was less,variation of chromosome and their number were more,from 2n=20,30,40,60.The results made a simple systematics of duckweeds inferenced from morphological data found.It was important for the research of cytology and systematics of duckweed.
