Global water use efficiency saturation due to increased vapor pressure deficit

Science, 2023
The ratio of carbon assimilation to water evapotranspiration (ET) of an ecosystem, referred to as ecosystem water use efficiency (WUE eco ), is widely expected to increase because of the rising atmospheric carbon dioxide concentration ( C a ).

Limited-transpiration response to high vapor pressure deficit in crop species

Plant Science, 2017
Water deficit under nearly all field conditions is the major constraint on plant yields. Other than empirical observations, very little progress has been made in developing crop plants in which specific physiological traits for drought are expressed. As a consequence, there was little known about under what conditions and to what extent drought impacts

A vapor pressure deficit effect on crop canopy photosynthesis

Photosynthesis Research, 1990
Canopy CO2-exchange rates (CER), air temperatures, and dew points were measured throughout ten days during the 1987 growing season for cotton (Gossypium hirsutum L.), grain sorghum [Sorghum bicolor (L) Moench], and five soybean [Glycine max (L) Merr.] cultivars, and throughout seven days in 1988, on maize (Zea maize L.).

Time Lag of Stem Water Deficit in Response to Increased Vapor Pressure Deficit

Forest Science, 2023
Abstract Vapor pressure deficit (VPD) shows a gradually increasing trend that forces trees to produce ecological memory with time-delay characteristics to drought year by year. The reversible stem diameter variation of trees can serve as an indicator for tree water status.

Vapor Pressure Deficit Control Strategies for Plant Production

IFAC Proceedings Volumes, 1998
Abstract Research to develop control strategies to implement vapor pressure deficit (VPD) control for plant propagation is presented. Recently designed and constructed lowcost chambers serve as the platform for this discussion, although results can be generalized to any other equipment in which both air temperature and humidity can be simultaneously ...

Vapor Pressure Deficit Control Algorithm for Plant Studies

IFAC Proceedings Volumes, 2000
Abstract A crop to air Vapor Pressure Deficit (VP Dcrop-air ) control algorithm was developed from analysis of energy balances on bedding plants in a sunlit plant growth chamber (SPGC). The control algorithm was implemented in the SPGC using a computer control interface, and system tests were conducted to determine the performance of individual ...

Relative Humidity or Vapor Pressure Deficit

Ecology, 1936
Being well aware of the profound importance of evaporation as a factor affecting plants and animals, biologists are careful to regulate or observe it in experimental work. Evaporation is a dynamic process and represents the net difference between the number.

Response of maize (Zea mays L.) towards vapor pressure deficit

Environmental and Experimental Botany, 2021
Abstract The changing atmospheric wetness and dryness in the background of global warming is an important issue for maize cultivation. The objective of this study was to evaluate the physiological response of maize towards vapor pressure deficits (VPDs).
