Fig. 11.1. Stomatal aperture in response to environmental parameters (light, temperature,
VPD,C02 air) and to leaf or plant internal parameters (leaf water, ABA, C02 Ieat). VPD
Water vapor pressure deficit between leaf and air; E evaporation; A assimilation; D
diffusion; leaf water leaf water potential and water content; ABA abscisic acid; boldface
arrows relevant in this study
Fig. 11.2. Gas exchange chamber with a microscope gliding stage. A leaf of Tradescantia
albiflora is fixed by a clamp (c) above the microscope objective lens. Leaf temperature is
measured by a thermocouple (T) fixed by a second clamp. A quantum flux sensor (Q) is
installed near the conditioning unit (CU). The conditioning unit is attached to the cuvette
(right-hand side of the picture)
