Leaf Water Potential Response to Transpiration by Citrus
Physiologia Plantarum, 1974AbstractThis paper reports on further studies of a model for interpreting leaf water potential data for Citrus. Experimental data confirmed the assumption that the ratio of vapor pressure deficit to leaf diffusion resistance adequately estimates transpiration when leaf‐to‐air temperature differences are small.

Field Measured and Simulated Corn Leaf Water Potential
Soil Science Society of America Journal, 1978Abstract The dynamic nature and magnitude of field‐measured leaf water potential for sweet corn ( Zea mays L.) was compared with that predicted by the model TROIKA. Some plant parameters for corn were estimated from the literature and field observation, whereas the moisture ...

Transpiration and leaf water potentials of wheat in relation to changing soil water potential
Australian Journal of Agricultural Research, 1977Changes in the transpiration rate of wheat in drying soils were followed in experiments in which plants were grown in two small weighable lysimeters in a glasshouse. Hourly measurements of soil water potential (?s) were made at three depths in each lysimeter.

Silver-Foil Psychrometer for Measuring Leaf Water Potential in situ
Science, 1972The water potential of leaves in situ can be measured without temperature control with a miniature, single-junction psychrometer constructed from silver foil and attached to the leaf with a silver-impregnated, conductive coating. The temperature of the psychrometer has been found to stay within 0.025°C of the temperature of a simulated leaf when the ...

The water potentials of canola branches and leaves were compared using a pressure chamber to determine whether they produced similar results. This study also investigated the magnitude of errors in the water status of canola resulting from re-cutting the branches, and the effects of delaying readings.

Leaf shrinkage decreases porosity at low water potentials in sunflower
Functional Plant Biology, 2007Leaves often shrink significantly when soil water is limited. For gas exchange measurmements, the shrinkage can require correction for changing amounts of tissue in the apparatus. In sunflower plants (Helianthus annuus L.), a comparison was made between mathematically-corrected transpiration and clamping leaves at their original turgid size without ...

Plant and Soil, 1994
The relationship between water potential and relative water content (water content in percentage of full hydration) is a characteristic of plant tissues, that may vary with environmental conditions. It is used here to compare leaf water relations of ten species coexisting in a semiarid grassland community (Festucetum vaginatae danubiale) in Hungary ...

Psychrometric Measurement of Leaf Water Potential: Lack of Error Attributable to Leaf Permeability
Science, 1965A report that low permeability could cause gross errors in psychrometric determinations of water potential in leaves has not been confirmed. No measurable error from this source could be detected for either of two types of thermocouple psychrometer tested on four species, each at four levels of water potential.

The Components of Leaf Water Potential I. Osmotic and Matric Potentials
Australian Journal of Biological Sciences, 1967Osmotic potential ('IT) resulting from solutes should be distinguished from matric potential (T) resulting from adsorption by the tissue matrix. The usual methods of measuring so·called "osmotic potential" actually give not only 'IT but also part or all of T.
