Abstract
The effects of enhanced UV-B radiation were studied on the growth and productivity of six field grown soybean cultivars. Control plants received ambient levels of UV-B radiation while experimental plants received daily doses equivalent to those expected on the summer solstice under clear sky conditions with a 16% and 25% ozone depletion at College Park, Maryland (39°N latitude). Plants were harvested at several reproductive growth stages. Enhanced UV-B radiation affected biomass allocation, total plant dry weight, average seed dry weight, and seed protein and lipid concentrations. Derived growth characteristics of UV-B irradiated plants (relative growth rate, net assimilation rate, leaf area duration and height growth rate) were also significantly different from controls. These effects were both cultivar and UV-B dose dependent.
