Studies on the relation between plantlet morphogenesis and changes of endogenous hormones in vitro culture of strawberry petiole were carried out. The result were as follows:
1 There were two morphogenesis ways of the regenerate plant from strawberry petiole in vitro culture. (1) The explant petiole dedifferentiated forming callus, then the callus rediffeientiated forming shoot and root;(2) The petiole differentiated forming callus, then the callus redifferentiated forming embryoid a...
