%X 对拟鹅观草属Pseudoroegneria 6种2亚种和鹅观草属Roegneria 3种植物的核型进行了研究,核型公式如下P. spicata (Pursh) A. L(o)ve,2n=2x=14=12m (2sat)+2sm; P. strigosa ssp. aegilopoides (Drobov) A. L(o)ve,2n=2x=14=12m (2sat)+2sm; P. libanotica (Hackel) A. L(o)ve,2n=2x=14=10m+4sm (4sat); P. stipifolia (Zern. ex Nevski) A. L(o)ve,2n=2x=14=12m (2sat)+2sm (2sat); P. strigosa (M. Bieb.) A. L(o)ve,2n=2x=14=12m+2sm (2sat); P. geniculata (Trin.) A. L(o)ve,2n=4x=28=20m+8sm (2sat); P. geniculata ssp. scythica (Nevski) A. L(o)ve,2n=4x=28=24m (2sat)+4sm; P. gracillima (Nevski) A. L(o)ve,2n=4x=28=24m (2sat)+4sm; 阿拉善鹅观草R. alashanica Keng,2n=4x=28=22m+6sm (2sat); 昌都鹅观草R. elytrigioides Yen & J. L. Yang,2n=4x=28=22m+6sm (4sat); 大丛鹅观草R. magnicaespes (D. F. Cui) L. B. Cai,2n=4x=28=22m+6sm.结合外部形态特征以及前人细胞遗传学和RAPD分析结果,推断R. alashanica、R. elytrigioides和R. magnicaespes很可能是在中国分布的拟鹅观草属植物.
