The Relationship between Transpiration, Root Water Uptake, and Leaf Water Potential
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]
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
<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 ...

Chloroplast Response to Low Leaf Water Potentials [PDF]
Quantum yields were measured for CO(2) fixation by sunflower (Helianthus annuus L.) leaves having various water potentials and for dichlorophenolindophenol photoreduction by chloroplasts isolated from similar leaves having various water potentials.

Water relations of woody perennial plant species
Aims: To describe the relation of various water status measures of woody perennial plants (predawn and midday stem and leaf water potential), to indices of physiological activity such as leaf conductance, vegetative growth and fruit growth and ...
