中文摘要：

渗透调节能力是植物抗逆性的最基本特征之一。作为一种重要的渗透调节物质,本文概要介绍了脯氨酸在植物体内的自然分布、生物合成和代谢途径、累积机理、其累积与植物的渗透调节的关系、累积的生理作用以及脯氨酸在玉米耐盐碱种质筛选中的应用等。

英文摘要：

Osmotic regulation ability is an essential character for plants to stress tolerance.As an important osmotic regulation substance,proline was discussed in the paper,which include its natural distribution,biosynthesis and metabolize pathway,accumulated mechanism,the relationship between proline accumulation and osmotic regulation,physiological function of proline accumulation in plants,as well as its usage in screening maize germplasms with salt-alkali tolerance.
