【摘要】 逆境胁迫下,草坪草通过改变自身外部形态、渗透调节、脱水保护、改变膜透性、增加酶活性等多种途径适应外界环境。文章综述了草坪草抗旱、抗盐机制,水分、盐分胁迫下草坪草外部形态的改变和生理生化特性(膜透性、SOD、POD、CAT活性、脯氨酸等渗透调节物质)的变化,草坪草对干旱和盐胁迫的适应机制,提出了在草坪草抗旱、抗盐性研究领域中存在的问题及研究的重点与趋势。更多还原

【Abstract】 Under adversity, turfgrass adapt to environment by change extraneous shape, osmoregulation, dehydrate protection ,change membrane, increase enzyme activity and so on. The mechanism of salinity and drought tolerance of turfgrass and the effect of moisture and salinity menace on the growth and biochemical or physiological changes (membrane permeability、activity of SOD、POD、CAT、 free praline etc.) of turfgrass are introduced in the article. Meanwhile adaptive mechanism of turfgrass to drought and salt stress and problems and emphasis and trend in research kingdom are introduced in the article.更多还原
