Effects of Thidiazuron on Micropropagation ot Ficus benjamina and F.Lyrata

Zhou Jun-yan and Zhang Zong-qin   

Abstract: Thidiazuron (TDZ) was ussed as a cvtokinin in micropropagation of two Ficus species for comparison of its activity was compared with BAP, a purinetype cytokinin. In the cultures of F. lyrata, TDZ in concentrations ranged from 0.01 to 0.02 mg/L could stimulate micropropagation. When the concentration of TDZ exceeded 0.2 ml/L, the shoots became somewhat malformed and vitrified in both species. Our result revealed that the cytokinin activity of TI)Z in stimulation of shoot proliferation was higher than that of BAP in the cultures of F. benjamina, but not in F. lyrata.

Key words: Thidiazuron (TDZ), Micropropagation, Ficus benjamina and F. lyrata
