Photoperiodism in Plants

Photoperiodism is the ability of plants to respond to light and darkness cycles. It regulates flowering, growth, and leaf loss in plants. Plants are classified as long-day, short-day, or day-neutral based on their response to light. Long-day plants need more than 12 hours of light to bloom, while short-day plants require less than 12 hours. Day-neutral plants flower regardless of light duration. Examples include Irises and lettuce for long-day, Chrysanthemums for short-day, and tomatoes for day-neutral.
