中国瓦韦属三种植物的细胞分类学研究
Cytotaxonomic study of three species of Lepisorus from China (Polypodiaceae)
摘要
Abstract
In the present paper, the chromosome numbers of three species of Lepisorus were reported for the first time. The chromosome number was 2n=42 in Lepisorus lineariformis;2n=144 in L. likiangensis;2n=50 in L. ti beticus. The haploid chromosome number n= 21 is a newly reported number in Polypodiaceae. Based on our study and previous data, we discussed the systematic significance of variability of chromosome numbers within the genus.关键词
