Influence of Enhanced UV-B Radiation on Crop Morphology and Physiological Function

Abstract

Abstract: The Influence of the enhanced UV-B radiation on crop production was reviewed to reveal the response mechanism of crops to the enhanced UV-B radiation and to provide the adaptation and resolution methods.The result showed that the enhanced UV-B radiation had an adverse effect on crop morphology of root,stem,leave systems and reproductive organs.It had a further effect on biomass and yield of crops.The effects on crop physiology of the enhanced UV-B radiation were mainly through the changes of chlorophyll,photosynthesis and mineral metabolism,which depended on the varieties and growing periods.

Key words: UV-B radiation, UV-B radiation, Crop morphology, Crop physiology
