Abstract: In our report， the native mango （Mangifera indica L.） seedlings originating from Hainan were used as the materials to investigate the physiological and ecological responses to long-term waterlogging stress from the aspects of morphology， growth and development， physiological and ecological adaptation. The results showed that all submerged mango seedlings can survive after the 80 d waterlogging stress （above 10 cm the surface of soil）， but the colors of the leaves gradually varies from green to yellow； the waterlogging stress can significantly promote the elongation of stem nodes and plant height， but aquatic adventitious roots are not formed； the waterlogging stress significantly reduce the relative water contents， photosynthetic pigment contents of leaves； the waterlogging stress can significantly increase the contents of soluble protein， soluble sugar and starch of leaves； the relative conductivity of leaves is significantly stimulated by waterlogging stress. Additionally， the results also suggested that Mango species has certain waterlogging tolerance and can be used as ecological restoration tree species in special wetlands to increase species diversity and improve landscape.
