Yup - most tropical growers know that, and the temperate ones definitely do. It's part of why Ecuador is one of the most prolific banana-producing nations on the planet: even in the south our days don't vary by more than 5 minutes a year, and this means that the plants bloom faster and set larger bunches.
It occurred to me this information may be useful for an indoor grower. Artificial lighting may be required to ensure a sufficient photoperiod.
Good point - you can probably accelerate the development of an indoor banana by playing with the photoperiod - the article mentioned that for foliar output days of more than 12 hours were probably desireable, with a drop to 12 hours light to stimulate fruiting. However, you have to also take into account the banana's genetic programming: it's not going to fruit before 40-48 leaves. Period.
