摘　　要：羊草又称碱草,是我国北方重要的优质饲草之一,广泛分布于欧亚大陆草原东部,具有显著的生态学意义.自然界中羊草存在叶色的差异,可依据叶色将其分为灰绿型和黄绿型两种生态型,二者在自身结构及抗逆特性等方面均表现出一定程度的差异.本文综合分析了两种生态型羊草在生理特性、叶绿体、种群水平以及对胁迫条件的响应等方面的差异,这些探讨有助于增进对植物趋异类型分化的理解,以期为相关领域的研究者提供有益的参考.Leymus chinens,also known as alkali grass,is one of the important high-quality forage grasses in the northern part of China,which is widely distributed in the eastern part of the Eurasian steppe,and has significant ecological significance.In nature,there are differences in leaf color of Leymus chinens,which can be divided into two ecotypes based on leaf color:gray-green type and yellow-green type,both of which show a certain degree of difference in their own structure and resistance characteristics.In this paper,we analyze the differences between two ecotypes of Leymus chinens in terms of physiological characteristics,chloroplasts,population levels,and responses to stress conditions.These explorations will help to improve our understanding of plant convergent type differentiation and provided useful references for researchers in related fields.
