Changes in growth and yield ofPhaseolus mungo L.induced by UV-A and UV-B enhanced radiation

We investigated the effects of UV-A and UV-B enhanced radiation on plants ofPhaseolus mungo. Low doses caused varying responses in such growth and yield components as shoot and root lengths, leaf area, fresh mass and dry matter, pod numbers, and seed numbers and weights. Compared with the performances of the control plants, supplementation with UV-A radiation promoted overall growth, while UV-B radiation inhibited development Moreover, both sources of radiation caused reduced yields, although this effect was comparatively less in plants treated with UV-A radiation.
