Abstract

The young embryos of maize inbred lines Huangzao4,Zong31 were cultured in vitro and the important functions of plant hormones were studied.The results indicated that medium for high frequency embryogenic callus was MS+2.0 mg/L 2,4-D;MS+6-BA 0.5 mg/L+KT(1.0)mg/L+NAA 0.2 mg/L was better for the callus differentiation;MS+1.0mg/L NAA was good for root development and got almost the same survival rate as MS+NAA1.0 mg/L+MET(2.0)mg/L did.
