WebJan 15, 2024 · The regulation of plant transpiration was proposed as a key factor affecting transpiration efficiency and agronomical adaptation of wheat to water-limited Mediterranean environments. However, to date no studies have related this trait to crop performance in the field. In this study, the transpiration response to increasing vapor pressure deficit (VPD) … WebDec 17, 2024 · Our model also accounts for changes in atmospheric vapor pressure deficit (VPD), which we modeled following Murray : VPD = 611 × e 17.502 × Ta Ta + 240.97 − 611 × e 17.502 × Td Td + 240.97 (1) where T a is the average daily temperature in degrees Celsius and T d is the dew point obtained from MERRA2.

Synthesis of four global climate datasets reveals a sharp increase … WebMar 8, 2024 · 1 INTRODUCTION. Accumulating evidence indicates that Earth is currently undergoing a global “atmospheric drying” as a result of an increase in atmospheric water vapor pressure deficit (VPD), a phenomenon that is expected to further amplify as climate change intensifies (Dai et al., 2024; Ficklin & Novick, 2024; Jung et al., 2010; Liu & Sun, … greenport fire district

Plant Cell Environ 32 ... WebA strong increase in the mean annual air temperature during the past 50 years by up to 0.54 °C was recorded in the Altai region (45°–52° N; 84°–99° E) compared to the global value of 0.07 °C over the period 1901–2008. The impact of the climatic changes on the hydrology are complex in these mountainous forest ecosystems and not fully understood. WebAbstract Increasing vapor pressure deficit (VPD) increases atmospheric demand for water. While increased evapotranspiration (ET) in response to increased atmospheric demand seems intuitive, plants are capable of reducing ET in response to increased VPD by closing their stomata. We examine which effect dominates the response to increasing VPD ... fly to japan from canada
