Abstract
An indoor pot experiment along with laboratory analysis was done to study the influence of increased UV-B radiation on C and N metabolisms of winter wheat during elongation-pregnant and heading stages. An increase in UV-B radiation could significantly decrease the aboveground dry matter weight of winter wheat during elongation-pregnant and heading stages and the plant-mediated respiration rate in the former stage, but it induced no impact on respiration coefficient during both stages. There was less content of chlorophyll a and more arotenoid in UV-treated leaves than in the untreated ones during both stages. Also, the UV-treated leaves contained less soluble sugar during the elongation-pregnant stage. Although there was no change in nitrate contents and activities of nitrate reductase in the UV-treated leaves during heading stage, the UV treatment could increase glutamine synthetase activity in leaves significantly (P0.05). Furthermore, the UV treatment increased concentrations of soluble protein and free amino acid in leaves during both stages (P0.1).These results suggested that N metabolism of winter wheat could be accelerated by UV-B radiation increasing.
