The Promntive Effects of Ginseng on Rapid C1onal In Vitro Propagation of African Violet (Saintapulia tonantha Wendl.)

Xu Lin-qing ( Hui Lam hing)   

Abstract: 1. Leaf and petiole explants of 31 varielies of African Violet can be induced to regenerate plantlet on MS+0.1 mg/l BA+0.1 mg/l NAA agar medium within 4–6 weeks. 2. Instead of using MS hormone free agar medium, further culturing the explants in MS+ginseng root powder 250 mg/l liquid medium for another 4 weeks has improved the quantity and quality of the regenerated phmtlet. 3. A rapid elonal in vitro propagation protocol was described. The number of transplantable plantlet obtainedby this method was 100–200% more than that obtained by ordinary method. 4. The organogenesis of leaf explants of African Violet was examined by using scanning electron microscopy. The result was described and discussed.
