Effects of Leaf Hydrophilicity and Stomatal Regulation on Foliar Water Uptake Capacity of Desert Plants

Foliar water uptake (FWU) is one of the primary sources for desert plants. Desert plants’ capacity essential in maintaining balance carbon and water. However, there are few studies on FWU plants physiological ecological characteristics that lead to differences capacity. In order clarify strategies influencing factors ecosystems, this study measured contact angle, parameters, hydraulic parameters explore six effects leaf wettability The results showed all had capacity, among which leaves Nitraria sibirica Pall. Halimodendron halodendron (Pall.) Voss a high foliar rate (k) accumulation (FWU storage), Glycyrrhiza uralensis Fisch. k low storage. Populus euphratica Oliv., Apocynum hendersonii Hook. f., Alhagi sparsifolia Shap. Additionally, was mainly affected by stomatal regulation compared with structure. will help improve understanding adaptability
