Comparisons of Leaf Water Potential and Xylem Water Potential in tomato Plants [PDF]

open access: yesAustralian Journal of Biological Sciences, 1970
The rapidity and convenience of the pressure chamber technique for estimating leaf water potentials, especially under field conditions, has been remarked (Boyer 1967; Kaufmann 1968a, 1968b) and demonstrated (Klepper and Ceccato 1969). However, Kaufmann (1968a) showed that it is necessary to exercise caution .in using measurements made with the pressure

A novel, non-invasive, online-monitoring, versatile and easy plant-based probe for measuring leaf water status [PDF]

open access: yes, 2008
A high-precision pressure probe is described which allows non-invasive online-monitoring of the water relations of intact leaves. Real-time recording of the leaf water status occurred by data transfer to an Internet server.

Hydraulic trade-off and coordination strategies mediated by leaf functional traits of desert shrubs

open access: yesFrontiers in Plant Science, 2022
Desert shrubs play important roles in desertification control and vegetation restoration, which are particularly affected by droughts caused by climate change. However, the hydraulic strategies associated with hydraulic functional traits of desert shrubs

Midday measurements of leaf water potential and stomatal conductance are highly correlated with daily water use of Thompson Seedless grapevines [PDF]

open access: yes, 2011
A study was conducted to determine the relationship between midday measurements of vine water status and daily water use of grapevines measured with a weighing lysimeter. Water applications to the vines were terminated on August 24th for 9 days and again

Vine water deficit : among the 3 applications of pressure chamber, stem water potential is the most sensitive indicator

open access: yesOENO One, 2000
Vine water status is an important factor in grape quality. High tannin and anthocyanin content in red grape berries are related to moderate vine water deficits.

Leaf Water Storage and Robustness to Intermittent Drought: A Spatially Explicit Capacitive Model for Leaf Hydraulics

open access: yesFrontiers in Plant Science, 2021
Leaf hydraulic networks play an important role not only in fluid transport but also in maintaining whole-plant water status through transient environmental changes in soil-based water supply or air humidity.

Strategies of two tropical woody species to tolerate salt stress

open access: yesPesquisa Florestal Brasileira, 2017
This study aimed to evaluate the leaf primary metabolism in two woody species, Sterculia foetida and Bombacopsis glabra. Both species have seeds rich in oil and they are largely found in regions with irregularities in water availability.

The Components of Leaf Water Potential II. Pressure Potential and Water Potential [PDF]

open access: yesAustralian Journal of Biological Sciences, 1967
The relation between the relative water content (R) and the pressure potential can be expressed through the coefficient of enlargement (e). The assumption that e does not vary with R is for many leaves a useful first approximation even when R is so low that pressure potential is negative. e is estimated at between 7 and 84 bars for various leaf types.

Retrieval of Leaf Area Index (LAI) and Soil Water Content (WC) Using Hyperspectral Remote Sensing under Controlled Glass House Conditions for Spring Barley and Sugar Beet [PDF]

open access: yes, 2010
Leaf area index (LAI) and water content (WC) in the root zone are two major hydro-meteorological parameters that exhibit a dominant control on water, energy and carbon fluxes, and are therefore important for any regional eco-hydrological or ...

Osmotic adjustment, stomata morphology and function show contrasting responses to water stress in mesic and hydric grasses under elevated CO2 concentration

open access: yesPhotosynthetica, 2019
The physiological response of two species of grasses with C3 and C4 mechanisms syndromes, Napier grass (Pennisetum purpureum Schumach × Pennisetum glaucum (L.) R. Br) and hydric common reed grass (Phragmites australis (Cav.) Trin.
