Abstract
A rapid and accurate technique for assessing the wettability of leaves of Arachis hypogaea L. and certain other species was developed. The method quantifies the retention of water on the surface when water is drained from around vertically immersed leaves at a constant rate. Although the relationship between mean contact angle measurements and water retained was not strictly linear, the correlation between the two variables was extrememly high, r = 0.997 (P = 0.001). This constant drainage technique can be used in the greenhouse and field and with some species does not require leaf detachment from the plant.
