Summary
In spite of the ten times higher evaporative demand in a desert versus a coastal habitat, plants of populations of Heliotropium curassavicum from both show similar stomatal conductances in the field as well as under controlled conditions. The desert plants however have a plastic stomatal response to dry air growing conditions which results in a greater photosynthetic performance at negative water potentials. The root and stem resistance to water flow is lower in the desert plants resulting in the maintenance of a high transpiration rate without a large reduction in water potential.
