Beschreibungen/Notizen

• The effect of low doses of UV-A (320-400 nm) and UV-B (280-320 nm) radiation on photosynthetic activities in Phaseolus mungo L. was investigated under field condition. Supplementation of UV-A enhanced the synthesis of chlorophyll and carotenoids than the UV-B supplemented plants. Significant increase was seen in the concentration of UV-B absorbing compounds of UV-B treated plants. Increase of PS 2 activity in UV-A treated plants was seen. Changes in photosynthetic activity were measured in terms of PS 2 mediated O₂evolution and Chl a fluorescence.
