The plants may recover during the night when evaporation is reduced as the stomata closes. [2] In woody plants, reduced water availability leads to cavitation of the xylem. Wilting occurs in plants such as balsam and holy basil，and other types of plants. Wilting is an effect of the plant growth-inhibiting hormone, abscisic acid. With ...
