Leaf water relations and gas exchange response to water deficit of olive (cv. Cobrançosa) in field grown conditions in Portugal

摘要

[Aims] To evaluate the effects of changes in water stress and variable evaporative demand on water potential (Ψ), relative water content (RWC) and gas exchange during two consecutive years (2005 and 2006) providing insight into the mechanisms of stomatal control in the little-studied cultivar ‘Cobrançosa’.
