What is Photoperiodism?
Photoperiodism is defined as the response of animals and plants to the relative length of day and night. “Photo” means light and “period” means the length of time. Garner and Allard first studied photoperiodism in plants in 1920. It is the response of plants to the periods of day and night. Plants usually use this time to grow, develop, and reproduce. It is a fascinating process in which shoots modify themselves into flowering apices before flowering.
Photoperiodism: Meaning, Process and Examples
Photoperiodism is a biological response of plants and animals to change in the proportion of dark and light. Garner and Allard first studied photoperiodism in plants in 1920. “Photo” means light and “period” means the length of time. Plants require light to bloom. The duration when the plant is required to bloom is known as critical photoperiod. Photoperiodism helps to determine the flowering season of different types of plants.
