In an attempt to obtain critical evidence as to whether inert dusts affect cuticular or stomatal transpiration or both, investigations were conducted with coleus plants, which have stomata on only the lower leaf surfaces. Chemically inert dusts (silica, talc, and Bancroft clay) were applied to one leaf surface or the other, and the relative effects on the daytime and night water losses were measured. The results of these experiments show that for dusts to cause an increase in water loss the dust particles must be small, and the dust must be applied to the stomata-bearing side of the leaf when the stomata are open.
