Explanation:
Detailed explanation-1: -The rate of transpiration decreases with the closure of stomata, high humidity, high atmospheric carbon dioxide level, the low water content of leaf, shedding of leaf.
Detailed explanation-2: -When the air is still or there is no wind, humidity may buildup around the plant from transpiration eventually decreasing the amount of water being released. When there is wind present, this causes the air to be replaced constantly allowing the plant to transpire. Increased humidity has a reduces transpiration.
Detailed explanation-3: -Water Availability A decrease in water absorption causes the closure of stomata and wilting, thereby reducing the rate of transpiration.
