Temperature-driven vapor pressure deficit structures forest bryophyte communities across the landscape [PDF]

Biogeosciences
Atmospheric vapor pressure deficit (VPD) controls local plant physiology and global vegetation productivity. However, at ecologically crucial intermediate spatial scales, the role of VPD variability in forest bryophyte community assembly and the ...

Genotypic Variation in Peanut for Transpiration Response to Vapor Pressure Deficit [PDF]

Crop Science, 2010
ABSTRACTConservation of soil water resulting from decreases in stomata conductance under atmospheric high vapor pressure deficit (VPD) conditions is a possible approach for enhanced tolerance of water deficit by crops. Water deficit is usually a concern in peanut (Arachis hypogea L.) since it is frequently grown on sandy soils with low water‐holding ...

The Canopy Temperature Response to Vapor Pressure Deficit of Grapevine cv. Semillon and Razaki [PDF]

, 2015
The main objective of this study was to determine canopy-air temperature differential, which can be used to quantify crop water stress index (CWSI) for grapevine (Vitis vinifera L.) grown with drip irrigation during the spring cultivation period of 2005.

Dynamics of the Net Precipitation in China from 2001 to 2020

Remote Sensing
Net precipitation (NP) is the primary source of soil water essential for the functioning of vegetated ecosystems. By quantifying NP as the difference between gross precipitation and canopy interception evaporation, this study examined the dynamics of NP ...

Diurnal Variations of Gas Exchange Characteristics in Leaves of Anise Hyssop (Agastache foeniculum) under Normal, Drought Stress and Recovery Conditions [PDF]

Journal of Medicinal Plants and By-products, 2013
Net photosynthesis rate (Pn), stomatal conductance (gs) and transpiration rate (E) of anise hyssop were measured during the four cloudless days, in reference to diurnal fluctuations of leaf temperature (Tleaf), leaf vapor pressure deficit (VPD leaf) and ...

Climatology, Variability, and Trends in the U.S. Vapor Pressure Deficit, an Important Fire-Related Meteorological Quantity

, 2015
Unlike the commonly used relative humidity, vapor pressure deficit (VPD) is an absolute measure of the difference between the water vapor content of the air and its saturation value and an accurate metric of the ability of the atmosphere to extract ...

The relative role of soil moisture and vapor pressure deficit in affecting the Indian vegetation productivity

, 2023
Atmospheric aridity (vapor pressure deficit, VPD) and soil moisture (SM) deficit limit plant photosynthesis and, thus, affect vegetation carbon uptake.
