UV-B radiation affects crop plants. Growing interest has been shown in studying the effectsof UV-B radiation exclusion on crops since 1993. This article summarized the generalconsequences of UV-B radiation exclusion on crop plants from the aspacts of plant morphology,growth and development. UV-B exlusion has promoting effects on plant height, internodeand leaf size. UV-B exclusion increases root biomass and stimulates nodulation of legumecrops with increased number and size of nodules and enhances the leghemoglobin. Higherlevels of α-tocopherol is found in UV-B plants, which plays an important role in translocatingphotoassimilates from the leaves to the roots. UV-B exclusion could be a useful tool forphysiologists and molecular biologists to further address mechanisms involved in UV-Bradiation damage in crop plants.
