| 摘 要： | 本文报道了仲彬草属2个种和鹅观草属3个种的核型，其核型均为首次报道。结果如下：
Roegneria nutans，2n=4x=28=26m+2sm；R．abolinii，2n=4x=28=24m+4sm．R．aristiglumis，
2n=6x=42=32m+1Osm(2sat)；Kengyilia tahelacana，2n=6x=42=36m(2sat)+6sm(2sat)；K．
zhoasuensis，2n=6x=42=34m(4sat)+8sm．根据核型特征，K．tahelacana和K．zhoasuensis两个六位体种归入K.engyilia属是正确的。

| Abstract: | The karyotypes of 3 species of Roegneria and 2 species of Kengyilia were
analysed in this paper. They are all reported for the first time, and the karyotype
formulae are as follows: R. nutans, 2n = 4X= 28 = 26m+ 2sm; R. abolinii, 2n = 4X
=28 = 24m + 4sm; R. aristiglumis, 2n = 6X = 42 = 32m + 10sm (2sat); K. tahelacana
2n = 6X = 42 = 36m (2sat)+6sm (2sat); K. zhoasuensis, 2n = 6X= 42 = 34m(4sat)+ 8sm.
According to the characters of karyotypes, K. tahelacana and K. zhoasuensis havethe S, Y, P genomes of genus Kengyilia. |
