Abstract:
... From May to October 2006 we applied two water treatments in an olive orchard in south Spain with 38-year-old ‘Manzanilla’ trees at 7x5 m spacing: a) rainfed, with rainfall as the only source of water supply; b) FAO, in which the trees were drip-irrigated daily from May to September, to replace the crop water needs. The aim of this work was to evaluate the influence of the water treatments on both ...

Abstract:
... Drought is considered to be the main environmental factor limiting photosynthesis (AN) and, consequently, plant growth and yield worldwide. During photosynthesis, the pathway of CO2 from the atmosphere to the site of carboxylation in the chloroplast stroma has two main components: stomatal (gs) and mesophyll (gm) conductances. Both are finite and dynamic, responding to many abiotic factors, theref ...

Food and Agriculture Organization; hydraulic conductivity; irrigation; leaf water potential; leaves; olives; rain; rhizosphere; roots; shoots; soil water; soil water content; stomatal conductance; stomatal movement; trees
Abstract:
... We studied the response of leaf water potential (ψl), stomatal conductance (gs), leaf specific hydraulic conductivity (Kl) and percentage loss of hydraulic conductivity (PLC) in current-year shoots of 40-year-old ‘Manzanilla’ olive trees under three water treatments: Rainfed, in which rainfall was the only source of water; FAO, in which the trees were under localized irrigation to replace crop wat ...
