Abstract：In this study,we explored the effects of two plant growth regulators naphthalene acetic acid(NAA)and indole butyric acid(IBA)with different concentrations on the growth of Oocystis sp.The results showed that the concentration of NAA and IBA promoter the algal growth at the concentrations ranging from 0.1 to 0.5 mg/L.The optimal concentration of NAA and IBA was 0.25mg/L.The two regulators inhibited the growth of Oocystis sp.at concentrations higher than 0.5mg/L.After the in-depth study on the effects of the two regulators,we found that the combined use of NAA and IBA is better than that of separated use in promoting the growth of Oocystis sp.The optimal synergistic con-centration of both regulators was 0.25mg/L,and the concentration ratio was 1∶1.
