The relationship between the wettability and the density of stomata

Abstract

stomata are channels for respiration of plants, and they are vital to keep it unblocked. In nature, in order to avoid the surface stomata being covered by water and ensure the normal respiration of stomata, plant leaves in nature are realized by a variety of methods, among which the difference surface wettability plays a crucial role in the distribution density of stomata. To explore the relationship between the wettability and the stomata density, this thesis investigates how the top and bottom density of stomata on plant surface affect the survivability of elm leaves (plant in the Ulmaceae family). Here, we find its lower surface with superhydrophobic function is covered by large amount of stomata. While the bottom surface with hydrophilic performance is smooth and covered by a small amount stomata. This research reveals the significant of waterproof function to the survival of leaf and has potential application in air exchange underwater.
