| Abstract: | Supplementary UV-B (12.2 kJ m−2 d−1 UV-BBE) provided to Vigna radiata for 2 h d−1 suppressed the length of root, shoot and whole plants, number of leaves, total leaf area, leaf area index, specific leaf
mass, fresh and dry mass of leaves and shoot, relative growth rate and net productivity. In unstressed green gram plants (10
kJ m−2 d−1 UV-BBE), triadimefon (TRIAD) (20 mg dm−3) enhanced growth in all parameters over control. The growth promoting effect of TRIAD enabled the UV-B impacted plants to
overcome the growth inhibitions to varying degrees indicating its protective potential against UV-B stress.
