REGULATION OF PHYTOHORMONS ON THE REGENERATION OF SHOOT-TIPS OF ANTIRRHINUM MAJUS INTO PLANTLET IN VITRO

Tissue culture of Anlirrhium majus was experimented by using the tip of shoots asthe explants,and comparing the effects of NAA,IAA and 2,4—D on the formation of adventitiousbuds.The results indicated that the effect of NAA was the best formation of adventitiousbuds,5.0,7.0,9.0,11.0,13.0 mg/L BA combinated with 0.1,0.5,1.0,1.5,2.0 mg/L NAArespectively.The results show that combinations of the concentrations of BA 7.0—9.0 mg/L andNAA 0.1--0.5 mg/L were advantageous to the regeneration of buds and NAA was very importantfor callus growth.
