Abstract
Thinning of stratospheric ozone layer had been reported since last fifty years due to emission of chlorofluorocarbons, resulting in an increase in ultraviolet-B (UV-B) radiation. The present study was conducted to examine the effects of supplemental UV-B (sUV-B) radiation (+7.2 kJ/m2/s) on yield and quality of seeds and oil of two cultivars of mustard, (Brassica campestris) L. cv. Sanjukta and Vardan. Number of pods, harvest index, test weight and oil content decreased due to sUV-B exposure in both cultivars. Seed quality was also reduced under sUV-B in terms of protein, sugar and amino acid contents. Further, quality of oil was deteriorated due to increases in erucic acid, polyunsaturated fatty acid and ω-6 fatty acid contents and reductions in oleic acid and nervonic acid contents due to sUV-B exposure. Cultivar Vardan showed more negative impact on seed yield due to UV-B stress, whereas quality of seed and oil was more affected in Sanjukta. Results of the present study confirmed the potential loss in y...
