中文摘要：
在不同程度盐碱胁迫样地和生育期双重影响下，对松嫩草地羊草甜菜碱含量和甜菜碱醛脱氢酶（BADH）活性的变化进行了研究。结果表明：甜菜碱含量和甜菜碱醛脱氢酶（BADH）活性随着土壤盐碱化程度的加重而增加。在盐碱化程度最严重的6号样地，羊草中的甜菜碱含量和甜菜碱醛脱氢酶（BADH）活性最高；同一样地，随着生育期的不同，甜菜碱含量和甜菜碱醛脱氢酶（BADH）活性都表现为单峰曲线。在盐碱化程度最重的6号样地羊草叶片中积累了较高含量的甜菜碱可能是羊草耐受盐碱胁迫的主要原因之一。
英文摘要：
Under the double effects of different alkai and salt stresses and bearing stage, changes of betaine content and activity of betaine aldehyde dehydrogenase of Leymus chinensis were studied in the Songnen grassland.The results showed： With the aggravation of salinization and alkalization, content of betaine and activity of betaine aldehyde dehydwgenase increased. In sample No. six, which was the most serious in salinization and alkalization, content of betaine and activity of betaine aldehyde dehydrogenase of Leymus chinensis were the highest. In the same sample grassland, both betaine content and activity of betaine aldehyde dehydregenase displayed a single peak curve in different bearing-stages.In the same grassland, betaine content accumulation was higher in leaves of/eymus chinensis, which probably explains why Leymus chinensis can endure alkai and salt stresses.
