Hydraulic redistribution is a mechanism that ensures the survival of superficial roots in dry soil during late summer, as they are submitted during part of the day to a negative flux, coming from roots with access to deep water. This mechanism also enables the plant to continue exploring these upper soil layers, richer in minerals and organic matter and has been observed in many ecosystems, including Montado, i...
The identification of a reliable and practical water stress indicator and the corresponding threshold value, for irrigation scheduling, is a classical concern in water management in agriculture. This is not well solved for woody crops, especially those not traditionally irrigated, usually with large roots systems. Aiming to contribute to these studies, we measured water fluxes and some water stress indicators i...
