The daily course of photosynthesis in situ in the economic macroalgae Bangia fusco-purpurea
经济海藻红毛菜原位光合作用日变化

The daily course of photosynthesis of Bangia fusco-purpurea in situ was determined by using photosynthetic gas exchange and chlorophyll a fluorescence. The results showed that its photosynthetic rate and chlorophyll a florescence parameters in the emersed algae decreased quicker than that in the submersed algae in noon. When the emersed algae was resubmersed,all chlorophyll a fluorescence parameters could recover to the levels of the submersed algae in two hours,respectively. Insignificant fluctuation of ch...
