| 摘 要： | 甜菜碱是一种非毒性渗透调节物质,对维持逆境胁迫下果树的代谢和生存具有重要的生理意义,系统讨论了甜菜碱在植物胁迫条件下的作用机制。由于并非所有植物在胁迫条件下会产生内源甜菜碱,因此外源甜菜碱使植物获得抗性的研究受到广泛关注。现对不同途径添加外源甜菜碱在果树抗逆过程中所起的作用进行举例说明,试图为增强果树的抗逆性提供新的技术措施。

| Abstract: | Betaine as a non-toxic osmotic adjustment substance which has important physiological significance for maintaining metabolism and survival when fruit trees under stress,systematic discussion about the action mechanism of betaine in plants under stress conditions.Because not all plants could produce endogenous betaine under stress conditions,thus the studies of exogenous betaine improve the resistance of plants received extensive attention.This article illustrated the different ways by adding exogenous betaine would increase the stress resistance.Attempt to provide new technical measures for enhance the resistance of fruit trees. |
