Abstract
The long summer drought that characterizes mediterranean-climatic regions places severe constraints on the photosynthetic potential of the resident plants. In this section a variety of mechanisms are described that characteristic evergreen plants inhabiting these regions have evolved to adapt to the drought. These include such physiological mechanisms as osmoregulation in the case of Olea to midday stomatal closure in the case of Arbutus. Allocation to root biomass is also an important adaptive mode for enhancing drought tolerance by certain species. Differential allocation patterns apparently explain dissimilar productivities of Mediterranean pines which have similar photosynthetic capacities.
