The Evaluation of a Leaf-Water Potential Function for Corn

Transactions of the ASAE, 1981
ABSTRACT AN attempt was made in 1978 to estimate leaf-water potential from soil and atmospheric parameters with a simplified, theoretically based model explaining water movement thru the soil-plant-atmosphere system. The soil water potential at a 30 cm depth and the vapor pressure deficit were used as variables.

Psychrometric Measurement of Leaf Water Potential: Lack of Error Attributable to Leaf Permeability

Science, 1965
A 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.

Psychrometric Water Potential Analysis in Leaf Discs

1989
The importance of water potential (Ψ), and its components, in studies of plant-water relations is well recognized (Kramer 1983; Turner and Burch 1983). Although numerous methods are currently available for monitoring plant-water status, the use of thermocouple psychrometers for the determination of leaf Ψ under both field and laboratory conditions is ...

Relation of Soybean Leaf Water Potential to Soil Water Potential¹

Agronomy Journal, 1974
AbstractEstimation of plant water potential is a possible aid in irrigation scheduling. This work examined the relation of maximum and minimum soybean (Glycine max (L.) Merr.) leaf water potential to soil water potential. Maximum readings were taken near sunrise and minimum readings were taken between 1300 and 1500 CDT.

Measurement of Leaf Water Potential by the Dye Method

Ecology, 1967
The dye method for measuring leaf water potential is simple, inexpensive, and suitable for both laboratory and field work. Leaves are immersed in a graded series of solutions, and the solution which neither gains nor loses water is assumed to have a water potential equal to that of the leaf.

The Relationship between Leaf Water Potential and Stem Diameter in Sorghum

Agronomy Journal, 2001
Leaf water potential (ψl) represents a good indicator of the water status of plants, and continuous monitoring of it can be useful in research and field applications such as scheduling irrigation. Changes in stem diameter (Sd) were used for monitoring ψl of pot‐grown sorghum [Sorghum bicolor (L.) Moench] plants in a glasshouse.

Contact angle of water droplets in relation to leaf water potential

Agricultural and Forest Meteorology, 1988
Abstract The relationship between the contact angle of distilled water droplets and leaf water potential was measured as a function of time of day on three different types of leaf surfaces. Leaves of dry edible beans (Phaseolus vulgaris L.) were representative of a corrugated, relatively waxless surface; soybean leaves (Glycine max L.) were ...

Leaf water potential-leaf water deficit relationship for ten species of a semiarid grassland community

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 ...
