植物对增强UV-B辐射和SO2的响应(综述)

RESPONSE OF PLANTS TO ENHANCED UV-B RADIATION AND SO2

摘要:

酸雨、温室效应和地球臭氧层的破坏是目前世界上最受关注的环境问题。由于臭氧层的破坏而导致的大气UV-B辐射的增加以及空气中SO₂污染的加剧都会严重影响到植物和动物的生命活动。本文回顾和简述了近二十年来这两种环境胁迫因子对植物影响的研究概况。

Abstract:

Acid rain, greenhouse effect and depletion of earth's stratospheric ozone layer are most serious environmental problems in the world at present. Both plant and animal life are greatly affected by enhanced UV-B radiation due to destruction of ozone layer and by continued aggregation of SO₂ in air. A brief of the studies in the last two decades concerned with the effects of the two stress factors on plants are presented.
