干旱、淹水和低温胁迫对莲雾抗氧化系统的影响
Effects of drought, waterlogging and chilling stresses on antioxidant system of Syzygium samarangense
摘要
Abstract
[Ojective]To investigate the effects of drought, waterlogging and chilling stresses on vegetative growth and antioxidant system of wax apple (Syzygium samarangense).[Method]Potted wax apple trees were subjected to drought, waterlogging and chilling stresses in a temperature-controlled room. Trees which were normally watered and grown at room temperature were used as controls. Shoot growth was observed. The relative water content, malondiadehyde (MDA) content, and antioxidant levels of leaves were measured.[Result]Sprouting were prevented by all three stress treatments. Relative water content of the drought- and waterlogging-treated leaves decreased, but increased to control levels after relieving the stresses. Three stress treatments increased leaf MDA contents, superoxide dismutase (SOD) and ascorbic acid peroxidase (APX) activities, as well as ascorbic acid (AsA) and reduced glutathione (GSH) contents compared with control.[Conclusion]Drought, waterlogging and chilling stresses could control vegetative growth and increase the antioxidant level of wax apple.关键词
