中文摘要：

玉米（Zea maysL.）在生长期常常受到干旱的胁迫,而脱落酸（ABA）调节的生长响应是植物对逆境信号的一个基本反应。本文对近年来国内外有关ABA提高玉米抗氧化防护系统,保护细胞免受氧化损伤,增加可溶性渗透剂（如脯氨酸）维持细胞内的水分,以及与其它激素相互作用影响玉米器官发育等的研究进展进行综述,以了解ABA调控玉米根系、叶片和籽粒的耐旱机理。

英文摘要：

Maize（Zea mays L.） is an important crop which often is subjected to drought stress in growing season.And the growth mediated by abscisic acid（ABA） is a fundamental response of plants to environmental stress.Research results show that the pathways of ABA-strengthening maize drought-endurance include：enhancing antioxidant defense systems to protect cell from oxidative damage;increasing compatible osmolytes（such as proline,Pro） to maintain intracellular water potential;affecting maize organs development by the interactions with other hormones and so on.In this paper,the drought-tolerant mechanisms of ABA regulating maize roots,leaves and kernels are reviewed from above aspects.
