%X Aphanizomenon flos-aquae bloom appears regularly nearly at March in recent years.In order to investigate the response of the cyanobacterium A.flos-aquae to the combination of doubled CO2 concentration and salinity,an experiment was carried out.Growth rate,photosynthesis,maximal electron transport rate(ETRmax),the ratio of photosynthetic pigment chlorophyll a to phycocyanin(Chla/PC) and malondialdehyde(MDA) levels of A.flos-aquae were analyzed.The results demonstrated that salt stress caused decrease in A.flos-aquae growth by disrupting physiological processes,especially photosynthesis.Increased salinity lowered ETRmax.MDA content was increased when salinity elevated.And higher salinity has more distinct effect.Growth rate,ETRmax and Chla/PC could be enhanced by elevated CO2 concentration,while doubled CO2 reduced MDA content.
