Rising ozone concentrations decrease soybean evapotranspiration and water use efficiency whilst increasing canopy temperature.
• Here, we investigated the effects of increasing concentrations of ozone ([O(3)]) on soybean canopy-scale fluxes of heat and water vapor, as well as water use efficiency (WUE), at the Soybean Free Air Concentration Enrichment (SoyFACE) facility. • Micrometeorological measurements were made to determine the net radiation (R(n)), sensible heat flux (H), soil heat flux (G(0)) and latent heat flux...
متن کاملdeltaO of water vapour, evapotranspiration and the sites of leaf water evaporation in a soybean canopy.
Stable isotopes in water have the potential to diagnose changes in the earth's hydrological budget in response to climate change and land use change. However, there have been few measurements in the vapour phase. Here, we present high-frequency measurements of oxygen isotopic compositions of water vapour (delta(v)) and evapotranspiration (delta(ET)) above a soybean canopy using the tunable diod...
متن کاملCarbon dioxide enrichment and temperature effects on cotton canopy photosynthesis, transpiration, and water-use efficiency 1
The objectives of this study were to evaluate effects of ambient and double ambient [ CO2 ] at a range of growing temperatures on photosynthesis, respiration, transpiration, water-use efficiency and dry matter accumulation of cotton plants (Gossypium hirsutum L., cv. DPL 50). In Experiment I, plants were grown outdoors untiJ first bloom, then transferred into naturally lit growth chambers and g...
متن کاملWater use efficiency and evapotranspiration in maize-soybean relay strip intercrop systems as affected by planting geometries
Optimum planting geometries have been shown to increase crop yields in maize-soybean intercrop systems. However, little is known about whether changes in planting geometry improve the seasonal water use of maize and soybean intercrops. We conducted two different field experiments in 2013 and 2014 to investigate the effects of changes in planting geometry on water use efficiency (WUE) and evapot...
