Detailed explanation-1: -Photoperiodism is the phenomenon in which various physiological reactions like the flowering response to the relative length of day and night or dark or light periods. Short day plants are those plants that begin flowering when the days are shorter than their critical day length.

Detailed explanation-2: -The response of a plant to change in relative length of day and night is called photoperiodism.

Detailed explanation-3: -Many models have been suggested over the years, but today, most biologists think photoperiodism-at least, in many species-is the result of interactions between a plant’s “body clock” and light cues from its environment. Only when the light cues and the body clock line up in the right way will the plant flower.

Detailed explanation-4: -Photoperiodism is the physiological reaction of organisms to the length of night or a dark period. It occurs in plants and animals. Plant photoperiodism can also be defined as the developmental responses of plants to the relative lengths of light and dark periods.

Detailed explanation-5: -The relative length of day and night is known as photoperiod. Some plants need to be exposed to sunlight for a particular duration of time to induce flowering. This is the reason behind the seasonal blooming of flowers.
