Abstract
Soybean cultivar Nannong 99-6 was used to study the effects of waterlogging stress on growth and adaptive response to waterlogging in pot experiments.Results showed that long-term of waterlogging inhibited soybean growth.Under waterlogging,biomass,leaf area,chlorophyll content,photosynthesis rate(Pn) and other photosynthesis parameters were significantly lower than control.Hydrogen peroxide(H2O2) content was higher than control.Short-term waterlogging at seedling stage showed some positive effects on soybean growth.Biomass,stoma conductance(Gs) and transpiration rate(Tr) increased to various levels.Under waterlogging stress,the stem diameter of soybean was enlarged.Sucrose content,soluble sugar content and the ratio of soluble sugar to soluble protein were increased.The results suggested that soybean had adapted both morphologically and physiologically to waterlogging stress.
