SunLight :-

⟹ Plants transpire more rapidly in the light than in the dark. This is largely because light stimulates the opening of the stomata (a mechanism). Light also speeds up transpiration by warming the leaf.

Temperature :-

⟹ Plants transpire more rapidly at higher temperatures because water evaporates more rapidly as the temperature rises. At 30°C, a leaf may transpire three times as fast as it does at 20°C.

Wind :-

⟹ When there is no breeze, the air surrounding a leaf becomes increasingly humid thus reducing the rate of transpiration. When a breeze is present, the humid air is carried away and replaced by drier air.

Humidity :-

⟹ The rate of diffusion of any substance increases as the difference in concentration of the substances in the two regions increases. When the surrounding air is dry, diffusion of water out of the leaf goes on more rapidly.
