Selection of Appropriate Explants for Multiplication,Shoot and Root Induction in Tissue Culture of Daemonorops margaritae

This paper deals with the selection of appropriate explants for multiplication,shoot and root induction in tissue culture of Daemonorops margaritae. The results indicated that the newly formed explants at a length ranging from 1.1～2.0 cm are good for the multiplication,the explants at length ranging from 2.1～4.0 cm and without developed leaves are optimal material for shoot induction,while shoots at a height over 4 cm can be well used for rooting. All these results provided information for massive propagation of D. margaritae through tissue culture at industrial scale.
