HORTICULTURE

Detailed explanation-1: -Transpiration increases with the velocity of wind. If the wind blows faster, the water vapour released during transpiration is removed faster and the area outside the leaf does not get saturated with water vapour. So, higher rate of transpiration is recorded on a windy day rather than a calm day.

Detailed explanation-2: -Plants transpire more rapidly in the light than in the dark. This is largely because light stimulates the opening of the stomata (mechanism). Light also speeds up transpiration by warming the leaf. Plants transpire more rapidly at higher temperatures because water evaporates more rapidly as the temperature rises.

Detailed explanation-3: -Transpiration rate increases when the wind blows faster as water evaporates faster from the leaves.
