Study of Spathiphyllum‘Vicki’Shoot Tip Culture in Vitro and Rapid Propagation

The shoot tip of Spathiphyllum 'Vicki' was used as explant to study its conditions for rapid propagation, including disinfection time, bud proliferation and rooting culture, and so on. The result showed the best disinfection time of 0.1%HgClz was 8 rain. The best shoot induction medium was MS+BA 1.5 mg· L-1 and the induce rate was up to 86%. The best bud proliferation medium was MS+BA2.0+KT0.2+NAA0. 3, and the multiplication coefficient was 3.6. The best rooting medium was 2/3MS+IBA1.5+AC 0.15% +sucrose 3%, and the rooting rate was 95 ~. The peat soil. and pearlite matrix had a ratio of 10 : 1, which was suitable for transplanting.
