\nDecreasing humidity increases the rate of transpiration, while decreasing light intensity decreases the rate of transpiration.
\n<\/section>\n
\n– Transpiration is the loss of water vapor from plants, primarily through stomata on leaves.
\n– Humidity affects the water potential gradient: Lower humidity in the air increases the difference in water potential between the leaf’s interior and the surrounding air, driving water vapor out faster.
\n– Light intensity affects stomatal opening: Generally, stomata open in the light to allow CO2 intake for photosynthesis. Reduced light intensity causes stomata to close, reducing water loss through transpiration.
\n<\/section>\n
\nOther factors affecting transpiration rate include temperature (higher temperature increases evaporation), wind speed (moderate wind increases, strong wind can decrease by drying the leaf surface and causing stomatal closure), and soil water availability (low water availability leads to stomatal closure).
