Abstract

The physiologically most important function of the plant cuticle is to control the loss of water and of inorganic and organic constituents of plants via the surfaces of leaves and fruits. In a polluted environment, the cuticle may also affect the rates of uptake of extraneous chemicals. It will be shown how the essential transport properties of plant cuticles can be determined experimentally using intact leaves, isolated cuticles, and reconstituted cuticular waxes. The transport properties will be related to the physico-chemical properties of the permeants in order to achieve a general description of pollutant transport across the leaf/atmosphere interface and to assess the relative contributions of the cuticular and the stomatal pathways to the total flow rate. The correlation of the transport properties of cuticles with their chemical composition will be discussed and a model of the molecular structure of the transport-limiting barrier of the cuticle and of epicuticular waxes be presented. The effects of chemicals of anthropogenic and biogenic origin on cuticular permeability will be described quantitatively.
