Historical changes of temperature and vapor pressure deficit during the crop growing season in Iran
Climate change variables have rarely been analyzed specifically for the growing season of crops. In this study, changes in minimum (Tmin) and maximum temperature (Tmax), daily maximum saturated vapor pressure (VPsat) and estimated daily VPD weighted for transpiration (VPDtran) were examined at five locations in Iran over 40 years during the growing seasons of chickpea and maize. The results of ...
متن کاملA New Vapor Pressure Equation
The Wagner equation for prediction of vapor pressure has been modified in order to improve it accuracy. On the basis of this modifications, development of a new equation for prediction of vapor pressure is outlined. Examples of the use of the equation for obtaining vapor pressure for a total of 94 pure substance are given. The proposed equation combines simplicity and accuracy and performs as w...
متن کاملPressure Dependence of Liquid Vapor Pressure: An Improved Gibbs Prediction
A new model for the vapor phase of a pressurized liquid called "the cluster model: which is originally introduced in this work, along with an accurate equation of state for the liquid phase called the LIR, is used to derive an accurate equation for the vapor pressure of liquid as a function of external pressure. The chemical Potential of both phase have been found to be in good agreement wi...
متن کاملThe evolution of mechanisms driving the stomatal response to vapor pressure deficit.
Stomatal responses to vapor pressure deficit (VPD) are a principal means by which vascular land plants regulate daytime transpiration. While much work has focused on characterizing and modeling this response, there remains no consensus as to the mechanism that drives it. Explanations range from passive regulation by leaf hydration to biochemical regulation by the phytohormone abscisic acid (ABA...
متن کاملLinking Turgor with ABA Biosynthesis: Implications for Stomatal Responses to Vapor Pressure Deficit across Land Plants.
Stomatal responses to changes in vapor pressure deficit (VPD) constitute the predominant form of daytime gas-exchange regulation in plants. Stomatal closure in response to increased VPD is driven by the rapid up-regulation of foliar abscisic acid (ABA) biosynthesis and ABA levels in angiosperms; however, very little is known about the physiological trigger for this increase in ABA biosynthesis ...
