Abstract:
Taking one-year-old jujube head of Zizyphus jujuba Mill cv.Lingwuchangzao as explant,the effect of rooting in vitro，optimizing medium for superior stocks of plantlets propagation were studied.The results showed that maintain the content of KH2PO4，MgSO4?7H2O，CaCl2?2H2O at a certain level，control the concentration rate of KNO3 and NH4NO3 between 0.9 to 2.0，the rooting rate of plantlets will increase obviously，comparing with the conventional medium 1/2 MS，the rooting rate will ascend from 56.7% to 84% above，some characteristics such as root No.per plantlet and root length per plantlet which were correlated to rooting quality rised significantly too.
