核型分析是生物物种分类的重要依据之一,裸燕麦据国内外报导并不一定只是一个物种,我们对五个六倍体裸燕麦材料进行了核型分析,体细胞的染色体数虽是42,但核型所有明显不同,由此可以以为六倍体裸燕麦也不一定只有一个种。
Karyotype analysis is one of the important bases for taxonomic classification. Naked oats are not necessarily the only species reported in China and abroad. We analyzed the karyotypes of five hexaploid naked oats. The number of somatic chromosomes was 42 , But all karyotypes are obviously different, which means that it is not necessarily a single species of hexaploid naked oats.
