In order to study the rapid propagation technique of Zizyphus jujuba by tissue culture,take the leaf of tissue culture seedlings of Chinese dates named as Muzao,Junzao and Goutouzao as explants.Through adventitious bud redifferentiated from the calli,a highly effective plant regeneration system was established.The results showed that explants of different genotype or different position of same genotype are different in cultured effects.The first to third leaves backwards from shoot-tip to down are suitable ...
