The percentage of necrotic leaf area was evaluated after resaturation, and necrosis of 1-2% defined as ``incipient injury{''}. The relative water content at incipient injury was higher in the dry summer than in the humid winter. Osmotic potentials of young leaves decline rapidly during leaf maturation; the values are not closely coupled to desiccation tolerance. The results are discussed with reference to the evolutionary origins of Quercus ilex, an Arcto-Tertiary element of the Mediterranean flora.</style></abstract></record></records></xml>
