新疆艾丁湖极端环境条件下盐角草的耐盐机制研究

盐角草属植物(Salicornia L.)是地球上迄今为止报道的最耐盐的陆生高等植物类群,是重要的耐盐基因供体及研究耐盐机理的模式植物。盐角草（S.europaea）为盐角草属一年生茎肉质化真盐生植物，在中国沿海及内陆两种环境下均具有极其广泛的分布区，也是极最具潜力的油料、饲料、钠盐工业原料的资源植物。针对该种在研究中缺乏内陆环境条件下的耐盐机制的研究、结合该种耐盐机制研究现状，本研究拟以内陆极端环境- - 新疆艾丁湖分布的盐角草为研究对象，从个体、种群及群落层次对盐角草的耐盐机制进行较为深入系统的探索：力求从个体水平上阐明盐生草的植株形态及结构、生理生态、生活史应对盐胁迫的适应机制；在种群水平上阐明环境条件对种群分布的调控作用；在群落水平上阐明不同盐分条件下盐角草与群落其它共建种的种间联结关系。最终从不同层次上全面理解该种的耐盐机制，同时也为一年生真盐生植物的耐盐机制的研究提供参考。

Salicornia is the most salt tolerant plant reported on the earth,and also is a model plant in the study of the salt tolerant gene donr and salt tolerant mechanism. S. europaea, an annual succulent euhalophyte,distributing extensively both in coastal and inland area, is an important resource plant as oil plant,fodder,Sodium salt material of industry. Since there is lack of research of Salicornia europaea under extreme enviroment in inland area,so in this study, Salicornia europaea distributing in Aiding lake was studied. We want to explore the salt tolerant mechanism of this species from different levels- - individual, population and community,clarify the mechanism on individual level from morphology and structure,ecophysiology,life history; clarify the mechanism on population level from regulation of enviroment on population distribution; clarify the mechanism on community level from analysis of interspecific association with other co-species. The purpose of this study is to comprehansive understand the salt tolerant mechanism of Salicornia europaea and provide basic data for reseach on other annual euhalophyte.
