The effect of drought, temperature and irradiation on leaf rolling in Ctenanthe setosa

Abstract

The effects of drought, temperature and irradiation on leaf rolling of Ctenanthe setosa were studied. Water deficit and air temperature were the most important, and have a synergistic effect on the degree and number of the rolled leaves. Irradiation also increased the rolling together with the water deficit but not alone. The stomata were open in rolled leaves.
