【摘要】 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。更多还原

【Abstract】 Roegneria is the biggest genus in Triticeae Damort.There were different views and points regarding whether Roegneria belonging to Elymus or not.This paper summarized taxonomy history,research progress on phonological,cytological,bio-chemical and molecular markers of Roegneria.Viewing from different aspects results,it was generally considered that there was a big genetic difference between Roegneria and Elymus;Roegneria should be regarded as a separate genus.However,some people still thought Roegneria and Elymus are the same genus.The phonological traits and geological distribution of Roegneria was also described in detail.更多还原
