The Retention of Aqueous Suspensions on Leaf Surfaces

Abstract

A method has been devised, using lycopodium, for studying the contribution of leaf surface characteristics to the wetting of leaves and the retention of particles applied as suspensions. Plants have been classified according to wettability, in relation to particle distribution and surface roughness. The recession of liquid on leaves of Rumex obtusifolius was studied in detail and the contributing factors analysed.
