小葱(Allium ascalonicum L.)的染色体多态性研究
Chromosomal Diversity of Allium ascalonicum L.
摘要
Abstract
In this study, somatic chromosomes were counted and the karyotypes were determined in 38 individuals from a population of Allium ascalonicum L. Five karyotypes were found, 2n =2x =12m +2sm +2st (2SAT)for 3 individuals, 2n=2x=14m+2st (2SAT)for 17 individuals, 2n=2x = 12m+2sm+2st+lB for 7 individuals, 2n=13m+2st (2SAT)for 5 individuals, 2n=10m+2m(2SAT)+2sm+lst for 6 individuals. Chromosomal diversity in A. Ascalonicum, including aneuploid and B chromosome was found and its possible causes were explained.关键词
