B ) to induce triploid.A number of them were cultured to the stage of on larvae. The C. B concentrations employed were 0. 1～2. 5 mg/dm3. The treatments started at 5～20 min after fertilization and lasted for various periods of time from 10 to 40 min. The highest inducing rate was 62. 5%.It was obvious that haaer C.
