Title: Effects of waterlogging on growth and physiological changes of winter rapeseed seedling(Brassica napus L.)
Abstract: Pot experiment was conducted to investigate the influence of long-term waterlogging on growth and physiology of winter rapeseed(Brassica napus L.cv Zhongshuang 9) seedlings.Results showed that growth and physiological properties of seedlings were increased at the beginning except for the photosynthetic pigment content.The maximum values,including plant biomass accumulation rate,root activity,soluble sugar,root MDA(malondialdehyde) content,SOD(superoxidedismutase) and CAT(catalase) activity of plant leaves,were obtained at 13d of waterlogging,and the maximum leaf MDA content was obtained at 24d of waterlogging.Results indicated that waterlogging stress significantly influenced rapeseed growth.They also indicated that seedlings growth could be maintained normal through regulating the metabolic activities under short-term waterlogging.If the stress was extended,seedling growth would be significantly inhibited.
