Abstract: Result show: 1. Plant hormones can accelerate seed germination of Vanilla planifolia. In three treatments (IAA 0. 1 mg/l+ BA 0.5 mg/l, BA 0.5 mg/l and IAA 0.5 mg/l+ BA 0.2 mg/l), the BA 0.5 mg/l treatment is the best, the percentage of seed germination is 46.9% in 31 weeks. It is 2.2 times of the control (no hormone is added in the medium); 2. The best temperature of incuba- tion is about 32-36℃, which is much higher than the ordinary temperature for tissue culture.
