Coatings of latex and silicone were applied to potted sweet orange seedlings which were then grown either in the glasshouse or outside. Measurements of growth and moisture usage over a 20‐day period indicated that latex reduced moisture usage significantly in both situations. Growth was not significantly different for the treatment in any one environment. Leaf burn was less on latexcoated plants but distortion of the growing shoot appeared greater than in silicone‐coated and uncoated plants. Latex coatings applied to perforated Al‐foil achieved considerable reductions in water vapor diffusion without completely covering the individual perforations. It is suggested transpiration reduction may be achieved by reducing stomatal pore size or by actually covering the pore.
