Vapour pressure deficit affects crop water productivity, yield, and quality in tomatoes

Agricultural Water Management
A high atmospheric vapour pressure deficit (VPD) hinders calcium absorption in tomatoes (Solanum lycopersicum L.), which severely reduces tomato yield, crop water productivity (WPcrop), and quality.

Effects of soil drought and vapour pressure deficit (VPD) on water use efficiency of tomato plants with contrasting endogenous ABA levels

, 2022
To investigate the interaction and elusive underlying mechanism of soil drought and vapour pressure deficit (VPD) on plant growth and water use efficiency (WUE), tomato plants (Solanum lycopersicum) (wild type and its ABA-deficient mutant) were grown ...

Disentangling Thermal and Hydraulic Drivers of Stomatal Conductance Under Hot Versus Dry Vapour Pressure Deficit Increases Using Water‐Use Efficiency

Plant, Cell &Environment, EarlyView.
ABSTRACT Predicting plant functioning in a warming world requires capturing its divergent responses to hot versus dry vapour pressure deficit (VPD) increases. Stomatal responses to VPD are typically studied without disentangling the effects of RH and temperature, creating uncertainties for future plant functioning.

Explicit Consideration of Plant Xylem Hydraulic Transport Improves the Simulation of Crop Response to Atmospheric Dryness in the U.S. Corn Belt

Water Resources Research
Atmospheric dryness (i.e., high vapor pressure deficit, VPD), together with soil moisture stress, limits plant photosynthesis and threatens ecosystem functioning.

High VPD mitigates the impact of soil drought in Pinus sylvestris L. through earlier stomatal closure [PDF]

Climate change scenarios foresee a drastic increase in atmospheric and soil droughts, driven by elevated vapor pressure deficit (VPD), in the future. However, the impact of coupled high VPD and soil water deficit on tree physiology is mainly untested ...

Hydraulic Activation of Stomata Induced by Hygroscopic Fertilizer Salts Alters Crop Carbon–Water Exchange: Field Evidence From Cereal Crops

Plant, Cell &Environment, EarlyView.
ABSTRACT Hydraulic activation of stomata (HAS), driven by hygroscopic salt films on leaf surfaces, can create an additional pathway for water loss beyond conventional stomatal vapour diffusion, yet this process remains largely overlooked in studies of plant–atmosphere interactions.

Unveiling the role of past vapor pressure deficit through soil moisture in driving tropical vegetation productivity

Environmental Research Letters
The impact of soil moisture (SM) and vapor pressure deficit (VPD) on gross primary productivity (GPP) variability in ecosystems is a topic of significant interest. Previous studies have predominantly focused on real-time associations between SM, VPD, and

Disruption of Fatty Acid Desaturase Gene Alters Aphid Resistance and Volatile Emissions in Sorghum

Plant, Cell &Environment, EarlyView.
ABSTRACT Jasmonic acid (JA)‐deficient msd3 sorghum mutants exhibit contrasting resistance phenotypes against sugarcane aphids (SCA; Melanaphis sacchari), which promotes aphid settling at early time points while providing antibiosis‐mediated resistance at later stages. Here we investigated the physiological, hormonal, and metabolic mechanisms underlying

Quantifying Dynamic Changes in Stem Storage‐Water Use and Rehydration in Mature Trees: A Study on Pinus sylvestris Trees Exposed to Increased Atmospheric and Soil Drought

Plant, Cell &Environment, EarlyView.
ABSTRACT Forests increasingly experience hot droughts, characterized by rising vapour pressure deficits (VPD) and declining soil moisture, highlighting the need to better understand water fluxes within trees. While stomatal conductance and transpiration are well studied, upstream fluxes such as internal stem water storage use and rehydration dynamics ...
