The potential impacts of an increase in solar UV-B radiation reaching the Earth's surface due to stratospheric ozone depletion have been investigated by several research groups during the last 15 years. Much of this research has centered on the effects of plant growth and physiology under ...

此外,UV-B辐射能够导致植物形态的各种变化,这种变化常与伴随着其它因子的不同而异。例如,UV-B辐射能改变植物的生长形态,使叶片卷曲,落叶增加,节间长度变短等[26]。 Table 1 Effects of enhanced UV-B radiation on plant morphology 形态特性 影响趋势 整株水平 - 叶面积 +/- 叶数量 +/- 枝(分蘖枝)的...
UV-B Effects on Terrestrial Plants and Aquatic Organisms UV-B effects on plants have been studied more frequently since local and global ozone depletion scenarios have given rise to the expectancy of increasing UV-B radiation (280鈥 320 nm) on the earth's surface. This increase has already be...
Keyword: ultraviolet light B(UV-B) radiation; plant; application; 0 、引言 太阳光中波长为100～400 nm的电磁辐射称为紫外线(UV)。根据纳米波长可以将其分为三类:长波紫外线(UV-A),波长范围400～320 nm;中波紫外线(UV-B),波长范围320～280 nm;短波紫外线(UV-C),波长范围280～180 nm[1]。UV-C几乎...

Long-term depletion of the stratospheric ozone layer contributes to an increase in terrestrial solar ultraviolet-B radiation. This has deleterious effects on living organisms, such as DNA damage. When exposed to elevated ultraviolet-B radiation (UV-B; 280鈥 315nm), plants display a wide variety ...
减少,UV～B的强度显著增加[10,11]. 自1801年发现紫外线以来,紫外线对生物的作用广泛受到重视.UV—B辐射增强可破坏核酸和蛋白 质,引起细胞变异,严重者可以致死,正是由于地表的UV—B辐射增强,以致植物的生育和产量受到严重影 响,地球上的生态平衡遭到破坏. ...
