Abstract
The early-maturity nectarine varieties,Huaguang and Shuguang,were used to study such factors as growth regulator concentrations and combinations,culture mediums,stage of embryo development,and low temperature that affected the regeneration of their embryonic axes.The results showed that the embryos 74 day after full bloom were the most suitable ones to use as the explants for the regeneration of the embryonic axes.75-day chilling treatment could increase the germination rate of immature embryos and was conducive to forming well-growing seedlings.The embryonic axes could be used to regenerate the plantlets and their hypocotyls and epicotyls showed no difference in this respect.The embryonic-axis regeneration of Huaguang performed best on the medium of G+TDZ 3.0 mg/L+KT 1.0 mg/L+NAA 3.0 mg/L and the optimal medium for the embryonic axis regeneration of Shuguangwas QL+TDZ 2.0 mg/L+NAA 0.5 mg/L.
