Sun Qingrong,Sun Hongyan, Zheng Hongjun, and Shi Yinping (Shandong Institute of Pomology,Taian 271000)
Shoot regeneration was obtained from leaves of seedlings of sour jujube(Zizyphus spinosus Hu. ). The highest regeneration rate was reached up to 47. 6% on medium WPM supplemented with 2 mg·ｌ~(-1) TDZ and 0.5mg·l~(-1)IAA. Shoot was transferred to MS supplemented with 0.5mg·l~(-1) BA for proliferation. Rooting was induced on 1/2MS supplemented with 0.3 mg·l~(-1) IBA and 2% sucrose. Rooting rate was very low, only 13. 1 %.
