Leaf anatomy variation, in plants grown at 9.8, 18, 27, and 36 Klux, is characterized by increased leaf thickness with increase in light. Leaves grown at lower light intensities have larger intercellular spaces than leaves grown at higher light treatments. Hooked trichomes were more frequent at highest light levels. Stomata frequency increased at the highest light intensity but the highest frequency was observed at 27 Klux. Stomatal diffusion resistance (rs) was greater on the upper surface than on the lower; and, on both surfaces, r increased with a decrease in light intensity.
