Summary Introduction

To explain:

Whether an individual would expect a predominance of long-day, short-day, or day-neutral plants near the equator.

Introduction:

Photoperiodism categorizes plants into long-day, short-day, and day-neutral plants. Plants that flower when they reach proper developmental stage after germination independent of photoperiod are known as day-neutral plants. Plants that flower when the night length is more than their critical photoperiod are called short-day plants. Plants that flower when the night length is less than their critical photoperiod are called long-day plants.
