The rate of transpiration in wind differs from rate in still air because;In still air, the water vapour lost from the plant accumulates in the air surrounding the leaf, thus increasing humidity which reduces saturation deficit between leaf cells and the atmosphere hence reducing transpiration rates.In wind, the water vapour from the plant(shoot) is carried away from the surrounding of the plant increasing the saturation deficit between leaf cells and the surrounding air; thus reduce rates of transpiration.
