On the Use of Sap Flow Measurements to Assess the Water Requirements of Three Australian Native Tree Species

Agronomy, 2021
The measurement of sap movement in xylem sapwood tissue using heat pulse velocity sap flow instruments has been commonly used to estimate plant transpiration. In this study, sap flow sensors (SFM1) based on the heat ratio method (HRM) were used to assess

Determination of Crop Water Stress Index by Infrared Thermometry in Grapefruit Trees Irrigated with Saline Reclaimed Water Combined with Deficit Irrigation

Remote Sensing, 2019
Water is not always accessible for agriculture due to its scarcity. In order to successfully develop irrigation strategies that optimize water productivity characterization of the plant, the water status is necessary.

Drought-Adaptive Mechanisms of Young Sweet Cherry Trees in Response to Withholding and Resuming Irrigation Cycles

Agronomy, 2021
The present work evaluates the main adaptive mechanisms developed by young sweet cherry trees (Prunus avium L.) to cope with drought. For this purpose, the young trees were subjected to two drought cycles with different water stress intensities followed ...

Methodology of stem water potential measurement on hedgerow olive orchards

Spanish Journal of Agricultural Research, 2023
Aim of study:To evaluate the effect of leaf covering, leaf position, leaf age, time and sample size in measurements of stem water potential (Ψstem) in olive hedgerow orchards. Area of study: The experimental orchards were located in the Centre of Spain (Toledo) Material and methods: Midday Ψstem was measured using a pressure chamber in two super ...

Continuous Stem Water Potential Measurements With Microtensiometry Reveal Species Identity and Soil Matric Potential Control of Stem Water Potential in Temperate Forests

Ecohydrology
ABSTRACT Water potential gradients govern water fluxes, and plants respond with species‐specific hydraulic traits that influence ecosystem function. While understanding these traits is key to predicting vegetation responses to climate change, traditional methods like the pressure chamber limit temporal resolution ...

Continuous Monitoring of Cotton Stem Water Potential using Sentinel-2 Imagery [PDF]

Remote Sensing, 2020
Monitoring cotton status during the growing season is critical in increasing production efficiency. The water status in cotton is a key factor for yield and cotton quality. Stem water potential (SWP) is a precise indicator for assessing cotton water status. Satellite remote sensing is an effective approach for monitoring cotton growth at a large scale.

Short-term physiological recovery and yield response of hedgerow olive orchards after prolonged water stress

Agricultural Water Management
The increase of drought periods implies that olive orchards could suffer severe water stress conditions for several years which could limit yield response when irrigation resumes.

HortNet417v1—A Deep-Learning Architecture for the Automatic Detection of Pot-Cultivated Peach Plant Water Stress

Sensors, 2021
The biggest challenge in the classification of plant water stress conditions is the similar appearance of different stress conditions. We introduce HortNet417v1 with 417 layers for rapid recognition, classification, and visualization of plant stress ...

Dendrometer as a water stress indicator for apple trees

Agricultural Water Management
The use of dendrometers to measure the stem diameter (SD) of trees provides information about their actual water stress levels. The Scholander chamber is currently the gold standard for measuring stem water potential and thus for quantifying the water ...
