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

Mucilage Polysaccharide Composition and Exudation in Maize From Contrasting Climatic Regions

Frontiers in Plant Science, 2020
Mucilage, a gelatinous substance comprising mostly polysaccharides, is exuded by maize nodal and underground root tips. Although mucilage provides several benefits for rhizosphere functions, studies on the variation in mucilage amounts and its ...

Circadian rhythms regulate the environmental responses of net CO2 exchange in bean and cotton canopies [PDF]

, 2017
Studies on the dependence of the rates of ecosystem gas exchange on environmental parameters often rely on the up-scaling of leaf-level response curves ('bottom-up' approach), and/or the down-scaling of ecosystem fluxes ('top-down' approach), where one ...

Sap flow of pecan trees in a US Southeastern orchard

Frontiers in Agronomy
Sap flow methods are widely used to estimate water use through transpiration in orchards. This study reports for the first time on pecan tree sap flow properties observed in a micro-irrigated orchard in the southeastern US in 2022 and 2023.

Occam's Razor, radiation-use efficiency, and vapor pressure deficit

Field Crops Research, 1999
Abstract Occam's Razor dictates that the hypothesis with the fewest assumptions in explaining the results is preferred. In a recent paper by Kiniry et al. (Field Crops Res. 56, 265–270, 1998), Occam's Razor was overlooked in favor of a hypothetical relationship of decreasing radiation use efficiency (RUE) with increasing vapor pressure deficit (VPD).

Defining critical water stress thresholds for adaptive management of alpine grassland phenology on the Qinghai-Tibetan Plateau

Geo-spatial Information Science
Alpine grasslands on the Qinghai-Tibetan Plateau, a critical carbon sink, face escalating water stress under climate change, yet the thresholds of compound soil-atmospheric drought triggering autumn phenology shifts remain unknown.

Hydraulic lift in Populus euphratica Oliv. from the desert riparian vegetation of the Tarim River Basin [PDF]

, 2010
In the Tarim River Basin, the desert riparian forest vegetation is under high-temperature and aridity stress However, the vegetation can grow continuously because of deep rooting that can reach groundwater, which can thus redistribute water into the ...

Is There Daily Growth Hysteresis versus Vapor Pressure Deficit in Cherry Fruit?

Horticulturae, 2021
The growth of cherry fruit is generally described using a double sigmoid model, divided into four growth stages. Abiotic factors are considered to be significant components in modifying fruit growth, and among these, the vapor pressure deficit (VPD) is ...

Influence of Time‐Averaging of Climate Data on Estimates of Atmospheric Vapor Pressure Deficit and Inferred Relationships With Wildfire Area in the Western United States

Geophysical Research Letters
Vapor pressure deficit (VPD) is a driver of evaporative demand and correlates strongly with wildfire extent in the western United States (WUS). Vapor pressure deficit is the difference between saturation vapor pressure (es) and actual vapor pressure (ea).
