Abstract
Effects of waterlogging stress on the physiological and growth responses of Spartina alterniflora and its adaptation mechanisms under long-term waterlogging conditions were studied.The results showed that the contents of soluble sugar and chlorophyll in leaves were lower than those of the control at the beginning of the experiment and then accumulated gradually.The contents of MDA increased remarkably at the beginning and then decreased.The activities of SOD and POD increased at the beginning and decreased subsequently.Under the waterlogging conditions,the height,node length and biomass ratio of underground vs.aboveground were lower than those of the control.The results from this study indicated that waterlogging stress could inhibit the growth of S.alterniflora,but the plant could effectively adapt to the stress by physiological and morphological adjustment.Therefore,waterlogging together with other control measures should be an effective way for controlling the expansion of S.alterniflora.
