Managing Water Stress in Olive (Olea europaea L.) Orchards Using Reference Equations for Midday Stem Water Potential

open access: yesHorticulturae, 2023
The irrigation surface of olive orchards has increased over recent decades. In zones affected, deficit irrigation scheduling is a must. The aim of this work was to study water stress management based on reference equations for midday stem water potential.

An investigation of vine water status as a major factor in the quality of Merlot wine produced in terraced and non-terraced vineyards in the Vipava Valley, Slovenia

open access: yesOENO One, 2023
Terraced vineyards are cultural landscapes with a special value. The increase in costs and the lack of professional workers make viticulture on terraces difficult to be maintained.

The effects of calcite silicon-mediated particle film application on leaf temperature and grape composition of Merlot (Vitis vinifera L.) vines under different irrigation conditions

open access: yesOENO One, 2020
Aim: This study examined whether the application of calcite-silicon mediated particle film (CaPF) at veraison can mitigate a drought-induced increase in leaf temperature on grapevine, thus contributing to improved leaf functionality, yield and grape ...

Leaf water potential meaning of different modalities of measurements

open access: yesOENO One, 2004
An experiment on Syrah in the Ecotron design of the AGRO Montpellier/INRA campus vineyard, with the control of different water regimes, allowed to test the physiological meaning and the field of application of different modalities of leaf water potential

Summer deficit irrigation in a hedgerow olive orchard cv. Arbequina: relationship between soil and tree water status, and growth and yield components

open access: yesSpanish Journal of Agricultural Research, 2013
Stem water potential (Phi-stem) is a useful tool for irrigation scheduling in tree crops, provided threshold values for growth and production are determined for each physiological period.

Temperature Effects on Radial Propagation of Water Potential in Cotton Stem Bark [PDF]

open access: yesPlant Physiology, 1973
Low temperature affects the lateral movement of water across the xylem-phloem boundary in intact cotton stems. There is a reduction in the effective diffusion coefficient relating free energy flux to water potential gradients with an associated increase in resistance to water flow.

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

open access: yesSongklanakarin 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)

Remote Sensing Energy Balance Model for the Assessment of Crop Evapotranspiration and Water Status in an Almond Rootstock Collection

open access: yesFrontiers in Plant Science, 2021
One of the objectives of many studies conducted by breeding programs is to characterize and select rootstocks well-adapted to drought conditions. In recent years, field high-throughput phenotyping methods have been developed to characterize plant traits ...
