HORTICULTURE

Detailed explanation-1: -Natural photoperiod is greatly influenced by latitude, and near the equator there is little variation in photoperiod.

Detailed explanation-2: -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-3: -Phototropism, plant growth towards or away from light, and photoperiodism, regulation of flowering and other developmental transitions by day/night length.

Detailed explanation-4: -Photoperiodic reactions can be reasonably predicted, but temperature, nutrition, and other environmental factors also modify an organism’s response. In animals, the regular activities of migration, reproduction, and the changing of coats or plumage can be induced out of season by artificially altering daylight.
