Experiments on pineapple hybrid seeds germination and seedling production in different media

[Objective]Ideal pineapple hybrid seeds germination medium and seedling production technology were explored for large-scale pineapple hybrid seed germination and seedling production.[Method]Pineapple hybrid seeds,harvested from the cross Philippines variety(female parent) × Australian Smooth Cayenne(male parent) in July 2010,were cultured in various media including MS basic culture medium,filter paper and nutritious soil mixture to compare germination and growth of seedling.[Result]Seedling emergence rate in MS medium treatment was recorded as the highest(30.9%) with vigorous seedlings.And transplant survival rate of these seedlings was 91.4%.Seedling emergence rate in filter paper treatment was only 19.1% with weak seedlings,and transplant survival rate was just 37.2%.Lastly,seedling rate of nutritious soil mixture treatment was 6.9% and transplant survival rate of seedling was 93.5%.[Conclusion]It was concluded that MS culture medium with high germination rate,seedling emergence rate and transplant survival rate was optimal for pineapple hybrid seeds germination and seedling production.
