Abstract: A laboratory test on the effects of 12 salinitywaterlogging stresses on the growth of Kandelia obovata seedlings was conducted. Nine growth indexes including seedling height, stem height, basal diameter, node number, leaf number, root biomass, stem biomass, leaf biomass and total biomass were measured. The results showed that salinity and salinitywaterlogging stresses had significant effects on the growth of K. obovata seedlings, while waterlogging stress had no significant effects on the seedling height, stem height, basal diameter, node number and leaf number, but had significant effects on root biomass, stem biomass, leaf biomass and total biomass. The growth and biomass of K. obovata seedlings decreased with increasing the salinity and waterlogging time. The principal components analysis showed that K. obovata seedlings would grow best under the 7‰ salinity+2 h waterlogging stress, while the 21‰+8 h combination was a critical stress.
