Abstract: By the methods of co-culture and cell-free filtrate addition, this paper studied the growth curves of Microcystis aeruginosa and Microcystis wesenbergii, and approached the allelopathy between them. The co-culture test revealed that there existed mutual inhibition effect between M. aeruginosa and M. wesenbergii. When the initial cell density of the two algae was higher than 0.5×10⁶ cells·mL^-1 and their mixed ratio was 1∶1,the growth of M. wesenbergii was suppressed significantly (P<0.05) due to the allelopathic effect of M. aeruginosa, and the growth of M. aeruginosa was slightly inhibited by M. wesenbergii. The cell-free filtrate of M. aeruginosa in its exponential phase inhibited the growth of M. wesenbergii, and, when the filtrate was added continuously into culture solution and the initial cell density of M. wesenbergii was less than 0.5×10⁶ cells·mL^-1, the growth of M. wesenbergii was suppressed significantly(P<0.01).
