Validation of an online system for the continuous monitoring of tree water status for sustainable irrigation managements in olive (Olea europaea L.)
2016
Abstract As a result of climate change a large reduction of agricultural water through improved irrigation management is a major need for agriculture sustainability. To this aim, always more sensitive sensors to monitor plant water status have been developed in recent years. Among them, the leaf patch clamp pressure probes are very promising for water management of olive but until now have been tested only in few environmental and management conditions. In this work these sensors have been tested for two consecutive years on two completely different management systems: a traditional rainfed orchard and a super high density (SHD) drip irrigated orchard. Within the SHD orchard the probes have…
Tree-to-tree variation in plant-based measurements as indicators of orange water status
2012
A study was conducted in order to determine the sensitivity of measured indicators of the plant water status in a citrus orchard. In ten adult orange (Citrus sinensis) trees, grafted on sour orange (C. aurantium) rootstocks and drip irrigated every second day, sap flow by Granier TDP probes, leaf and xylem water potential, gas exchange and leaf and canopy thermal imaging were hourly monitored all over the day. The evaluations were performed during two separate clear-sky days with different environmental conditions, respectively in the summer and autumn seasons. Variations of environmental components (reference evapotranspiration, solar radiation, vapour pressure deficit and temperature) wer…
