摘要
现阶段全球气候变化引起了人们的高度重视,臭氧(O_(3))浓度升高是其中问题之一。这一现象导致人们赖以生存的稻麦作物受到一定影响,因此我们必须加以重视和研究出解决的办法。EDU是现阶段有效缓解O_(3)胁迫的一个主要化学物质,对O_(3)胁迫植物具有一定的保护和缓解胁迫作用,但是其作用机制还未完全清楚。在已有研究的基础上,概述了EDU的使用方式和适宜施用浓度,在植物体内的运输和有效作用时间;总结了EDU对O_(3)胁迫下稻麦作物生长和形态参数以及产量的影响,并从生理生化和遗传学的角度探讨了EDU的作用机制。
The current global climate change has aroused people’s great attention,and the increase(O_(3))of ozone concentration is one of the problems.This phenomenon has affected the rice and wheat which people depend on for survival to some extent,so we must pay attention to it and develop solutions.EDU is a major effective chemical substances to alleviate O_(3) stress at present.It has certain protective and alleviating effects on O_(3) stressed plants.But the mechanism of action is not fully understood.On the basis of the existing studies,the use mode and appropriate concentration of EDU were introduced,as well as its transport and effective time in plants.The effects of EDU on growth,morphological parameters and yield of rice and wheat under O_(3) stress were summarized,and the mechanism was discussed from physiological,biochemical and genetic perspectives.
