Abstract

Photoperiodism appears via one manifestation or another in many if not most eukaryotic organisms, including plants and animals. In plants, reproduction is often controlled or influenced by response to relative lengths of day and night, and form of a plant (e.g., internode lengths, stem heights, leaf shapes) is virtually always influenced by photoperiod. Other plant responses, including tuber formation and even relative concentrations of various growth regulators and metabolities, are also influenced by photoperiod. Clearly, most if not all plants and animals of virtually any ecosystem are as they are in response to the photoperiods to which they have been exposed. Hence, the complete understanding of ecosystems must include an understanding of the photoperiodic responses of their components organisms.
