Microtensiometers Accurately Measure Stem Water Potential in Woody Perennials [PDF]
Plants, 2021 Stem water potential (Ψstem) is considered to be the standard measure of plant water status. However, it is measured with the pressure chamber (PC), an equipment that can neither provide continuous information nor be automated, limiting its use.

Modeling Stem Water Potential by Separating the Effects of Soil Water Availability and Climatic Conditions on Water Status in Grapevine (Vitis vinifera L.) [PDF]
Frontiers in Plant Science, 2019 Measuring seasonal plant water status is critical in choosing appropriate management strategies to ensure yields and quality of agricultural products, particularly in a context of climate change. Water status of grapevines is known to be a key factor for

Establishing a Reference Baseline for Midday Stem Water Potential in Olive and Its Use for Plant-Based Irrigation Management [PDF]
Frontiers in Plant Science, 2021 Midday stem water potential (SWP) is rapidly becoming adopted as a standard tool for plant-based irrigation management in many woody perennial crops. A reference or “baseline” SWP has been used in some crops (almond, prune, grape, and walnut) to account ...

Assessing water stress in a high-density apple orchard using trunk circumference variation, sap flow index and stem water potential [PDF]
Frontiers in Plant Science, 2023 IntroductionAutomated plant-based measurements of water stress have the potential to advance precision irrigation in orchard crops. Previous studies have shown correlations between sap flow, line variable differential transform (LVDT) dendrometers and ...

Stem Water Potential is a Sensitive Indicator of Grapevine Water Status [PDF]
Annals of Botany, 2001 Abstract Dawn leaf water potential (dawnΨ), leaf water potential (leafΨ) and stem water potential (stemΨ) were measured on mature leaves to determine non-irrigated vine water status in vineyards during the growing season. StemΨ was the most discriminating indicator for both moderate and severe water deficits.

Remote Sensing, 2021 The main challenge encountered by Mediterranean winegrowers is water management. Indeed, with climate change, drought events are becoming more intense each year, dragging the yield down. Moreover, the quality of the vineyards is affected and the level of

Stem Water Potential and Apple Size [PDF]
Journal of the American Society for Horticultural Science, 1995 The sensitivity of leaf (ψ leaf ) and stem (ψ stem ) water potential and stomatal conductance (g s ) to soil moisture availability in apple (Malus domestics Borkh.) trees ...

Primary Events Regulating Stem Growth at Low Water Potentials [PDF]
Plant Physiology, 1990 Cell enlargement is inhibited by inadequate water. As a first step toward understanding the mechanism, all the physical parameters affecting enlargement were monitored to identify those that changed first, particularly in coincidence with the inhibition.
