Which environmental factor is most significant for flowering?

Question

Quizplus · Accepted Answer

Day length, also known as photoperiod, is the most significant environmental factor for flowering in many plant species. This is because plants use photoperiod as a cue to determine the time of year and adjust their flowering accordingly. For example, long-day plants only flower when the days are longer than a certain threshold, while short-day plants only flower when the days are shorter than a certain threshold. Temperature, water availability, nitrogen availability, and light intensity can also affect flowering, but to a lesser degree than photoperiod.
