鹅观草属Roegneria是小麦族中最大的一个属,对于鹅观草属的归属问题,不同时期的学者拥有各自的看法和观点。根据国内外的研究资料,综述了鹅观草属植物的分类历史及围绕这一问题而展开的有关鹅观草属形态学标记、细胞学标记、生化标记和分子标记的研究进展情况,从几方面研究的结果来看,我国的大多数学者认为披碱草属和鹅观草属植物之间遗传差异较大,应把鹅观草作为一个独立的属对待,但也有少数人认为把鹅观草属和披碱草属合为1个属处理。此外,还对鹅观草的形态特征及地理分布进行了详细的描述。
Roegneria Roegneria is one of the largest genus in the genus Triticeae, and scholars of different periods have their own views and opinions on the ownership of the genus. According to the research data both at home and abroad, the classification history of the genus Agkistrodon and the progress on morphological, cytological, biochemical and molecular markers of the genus Agkistrodon are summarized According to the results of the study, most scholars in our country think that there is a large genetic difference between Elymus and Roegneria and should be treated as an independent genus, but there are also a few people who think that the concept of Goose Grass and Elymus together as a genus treatment. In addition, the morphological characteristics and geographical distribution of Goosegrass were also described in detail.
