| Abstract: | The research results on the influence of Cu pollution on physiology and biochemistry of sea-grass were summarized in last two decades in this paper,including accumulation characteristics of Cu in sea-grass and the related influence factors,impacts of Cu on photosynthesis of sea-grass and its tolerant mechanisms to Cu stress.Further research was pointed out that(1) Sub-cellular distribution and chemical forms of Cu under multi-stress of Cu and other heavy metals.(2) Effecting mechanisms of Cu on photosynthesis of sea-grass in terms of molecular and cellular level.(3) Transfer discipline of Cu among different tropical levels of sea-grass ecosystem.(4) The tolerant mechanisms of sea-grass under Cu stress. |
