Yes the eythylene gas does work. Pineapples also need plenty of sun to
really flower well and set fruit. A good blossom booster fertilzer
at 1/4 dilution is helpful too. I usually cheat, however. There is a
product called Etherel that is a hormonal blossom inducer. It works
very well with no ill effects. Remember that if you use the apple
trick or any hormones it could take 4-7 weeks before a terminal flower
spike begins to develop.

Good luck with your plant.
