对新麦草属（Ｐｓａｔｈｙｒｏｓｔａｃｈｙｓ）两物种新麦草（Ｐｓａｔｈｙｒｏｓｔａｃｈｙｓｊｕｎｃｅａ）和华山新麦草（Ｐｓａｔｈｙｒｏｓｔａｃｈｙｓｈｕａｓｈａｎｉｃａ）进行根尖染色体Ｃ－分带，获得清晰的Ｃ－分带带型，并对二者带型进行了描述。结果表明，二者Ｃ－分带带型有较大差异。Ｐ．ｊｕｎｃｅａ的Ｃ－分带带纹较Ｐ．ｈｕａｓｈａｎｉｃａ丰富，Ｐ．ｈｕａｓｈａｎｉｃａ所有染色体均显较强端带。通过二者带型比较，对华山新麦草是否仍应保留在新麦草属提出质疑，并提出了将新麦草和华山新麦草的基因组分别标为Ｎｊ和Ｎｈ以示区别的建议。 The C-banding of Psathyrostachysjuncea and Psathyrostachyshuashanica was performed on Psathyrostachys species, and the C-banding patterns were clearly identified. The band patterns of the two species were described. The results show that the two C-banding patterns are quite different. P. C-banding of juncea is more p Huashanica Enrichment, P. huashanica All chromosomes show a stronger band. According to the comparison of the two bands, whether or not P. huashanica still should be retained in the genus Pulsatilla was questioned, and the suggestion was made to distinguish the genomes of P. nobile and P. huashanica respectively as Nj and Nh.
