Measurement of stem water potential as a sensitive indicator of water stress in neck orange (Citrus reticulata Blanco) [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2008
Measurements of stem water potential, leaf water potential and stomatal conductance were simultaneously done in3-year old trees of neck orange. The trees were subjected to 3 levels of watering: 1) daily watering (control), 2) 4-dayinterval watering and 3)

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 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.
