Effects of Light Intensity and Potassium on Leaf Stomatal Activity of Ficus benjamina L.1

Abstract

Leaf diffusion resistances of Ficus benjamina grown in full sun were lower than those from 47% light exclusion. Scanning electron micrographs revealed 53% more stomata on sun leaves. High KC1 increased transpiration rates and foliar levels of K were increased in sun grown plants, but unaffected in shade grown plants.
