Abstract
Twenty-three soybean cultivars were grown in a greenhouse under a daily dose of either 0 or10.1 kJ/sq m biologically effective ultraviolet-B (UV-BsubBE) radiation until reproductive maturity. Of these, six selected cultivars were also grown in the field with similar enhanced levels of UV-B. UV-B radiation substantially affected vegetative growth and seed yield in both environments. The magnitude of response varied intraspecifically and was character specific. Under both greenhouse and field conditions, Forrest was the most tolerant to UV-B radiation based upon a combination of responses including plant height, leaf area, total dry weight, and seed yield. Using the same criteria, Shore and York were the most susceptible under greenhouse and field conditions, respectively. Additional comparisons revealed that UV-B sensitivity based on vegetative parameters was similar between greenhouse and field observations but based on seed yield differed markedly. This discrepancy might be related to environmental differences, particularly in the level of visible radiation between the two growth regimes. (Copyright (c) 1986, Pergamon Press Ltd.)
