DENDROLOGY

Detailed explanation-1: -The transpiration rate goes up as the temperature goes up, especially during the growing season. As the relative humidity of the air surrounding the plant rises the transpiration rate decreases. It is easier for water to evaporate into dryer air than into more saturated air.

Detailed explanation-2: -An increase in wind speed increases the rate of transpiration as water molecules are moved away from the leaf faster.

Detailed explanation-3: -Temperature: A rise in temperature increases the water loss by transpiration. Transpiration increases with an increase in temperature to a certain point. Stomata close when the temperature falls to very low or increases to very high ultimately ceasing the process of transpiration.

Detailed explanation-4: -The rate of transpiration decreases with decrease in temperature and decrease in light intensity.
