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

OENO 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.

Strategies of two tropical woody species to tolerate salt stress

Pesquisa 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.

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

Frontiers 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.

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

Australian 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.
