Summary Introduction
Introduction:
Flowering in plants is a process affected by photoperiodism. These photoperiodic responses presented by the plants are predictable and help in categorizing plants into two major categories. These are long-day plants, which flower during the season when days are longer than nights, and short-day plants, which flower in a season when nights are longer.
