Abstract
Shoot-tips with leaves of three fragrant petunia cultivars were employed as explants to carry out the studies on the effects of the ratio of BA,IBA and NAA on primary culture,subculture and root formation.Results indicated that obvious differences existed in the requirement of hormone concentration for regeneration and subculture among these three genotypes.The concentration of BA ranged from 0.1mg·L-1 to 1mg·L-1.For a given cultivar,high concentration of BA might induce callus from stem and leaf directly,and then adventitious buds were gained from the callus;moderate concentration of BA might induce both normal buds and adventitious buds;and low concentration of BA might induce normal buds from terminal and lateral buds.All the three cultivars produced root easily on 1/2MS medium supplemented with 0.25mg·L-1 NAAand 0.25mg·L-1IBA.
