Collecting Pineapple Seeds Collecting Pineapple Seeds
Most of us are unaware of the fact that pineapple seeds can be collected and used for propagating pineapples. In naturally grown mature pineapples, dark brown- or black-colored seeds are found embedded in the flesh of the fruit; however, commercially grown pineapples are seedless.
The only feasible way to produce pineapple seeds is via cross-pollination. Humming birds are common cross-pollination agents of pineapple flowers. In the case of commercially produced pineapples, presence of seeds is not encouraged as the fruit is much more enjoyable without them. So, commercial pineapple growers discourage cross-pollination.
Propagation by Seeds
Rinse the seeds obtained from a mature, ripe pineapple and sow them in moist potting soil. Keep the pot in a warm place that has a minimum temperature of 65 to 75° F.
Pineapple Seed Germination
It is possible to successfully germinate pineapple seeds by keeping them in wet paper towels placed inside sealed plastic bags. A period of 3 to 6 months is required for the seeds to germinate. Moist soil in a warm location is ideal for the germination of pineapple seeds.
Pineapple seeds germinate at a slow rate, unless treated with sulfuric acid. However, higher rates of germination with healthy seedlings can be achieved using untreated seeds. Occasional misting is a must for the healthy growth of these seedlings. The healthy seedlings can be transplanted after 1 year to 15 months, and they will start bearing fruits within 2 to 3 years.
