Effect of Leaf Water Potential on Internal Humidity and CO2 Dissolution : Reverse Transpiration and Improved Water Use Efficiency under Negative Pressure [PDF]

, 2017
The pull of water from the soil to the leaves causes water in the transpiration stream to be under negative pressure decreasing the water potential below zero.

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

, 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

The Relationship between Transpiration, Root Water Uptake, and Leaf Water Potential

Journal of Experimental Botany, 1979
The effect of changing the transpiration rate on leaf water potential and water balance has been examined to show if permeability of the plant (predominantly the roots) is constant or varies with the transpiration rate. Measurements of leaf effective thickness, water potential, transpiration, and uptake of water by roots were made on sunflower, barley,

Leaf Water Potentials Measured with a Pressure Chamber [PDF]

Plant Physiology, 1967
Leaf water potentials were estimated from the sum of the balancing pressure measured with a pressure chamber and the osmotic potential of the xylem sap in leafy shoots or leaves. When leaf water potentials in yew, rhododendron, and sunflower were compared with those measured with a thermocouple psychrometer known to indicate accurate values of leaf ...

Impact of soil water potential pattern on root water uptake distribution and leaf water potential

, 2021
<p>Root water uptake is a major process controlling water balance and accounts for about 60% of global terrestrial evapotranspiration. The root system employs different strategies to better exploit available soil water, however, the regulation of water uptake under the spatiotemporal heterogeneous and uneven distribution of soil water is ...
