Abstract: Inhibitory effects of Ceratophyllum oryzetorum Kom. on the growth of Microcystis aeruginosa Kütz. has been investigated. The results showed that the liquor cultured with C. oryzetorum and the extract of C. oryzetorum have differential inhibitory effects on M. aeruginosa. The high concentration of the liquor cultured with C. oryzetorum and the extract of C. oryzetorum can inhibit the growth of M. aeruginosa. The low concentration of them have no inhibitory effects on the growth of M. aeruginosa. And the tender plants have the best inhibitory effects on the growth of M. aeruginosa, the old plants can accelerate their growth. The extract of C. oryztorum can inhibit the growth of M. aeruginosa obviously at 20℃.

Key words: Microcystis aeruginosa Kü, tz., Ceratophyllum oryzetorum Kom., inhibitory effect
