Stomatal responses to changes in vapor pressure deficit . . . Stomatal sensitivity to D was correlated with Kleaf relative to total leaf area (r2 = 0 50), and did not differ between C 3 and C 4 species Transpiration (E) increased in response to D, but 8 of the 19 plants showed a decline in E at high D, indicative of an ‘apparent feedforward’ response
When Does Vapor Pressure Deficit Drive or Reduce . . . 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
Intra-specific variability of stomatal sensitivity to vapour . . . Stomatal conductance is regulated by many factors such as air vapour pressure deficit (D), which can be the pivotal one affecting leaf gas exchange in species particularly sensitive to D such as C avellana
Plant responses to rising vapor pressure deficit - Grossiord . . . Incorporation of photosynthetic and hydraulic traits in ‘next-generation’ land-surface models has the greatest potential for improved prediction of VPD responses at the plant- and global-scale, and will yield more mechanistic simulations of plant responses to a changing climate
Evolution of Mechanisms Driving the Stomatal Response to . . . The stomata in basal lineages of vascular plants, including gymnosperms, appeared to respond passively to changes in leaf water status induced by VPD perturbation, with minimal changes in foliar ABA levels and no hysteresis in stomatal action
Seasonal change in response of stomatal conductance to vapor . . . The concentration of abscisic acid (ABA) and the sensitivity of stomatal conductance (g s) to vapor pressure deficit (VPD) in the three trees in different seasons in Jinan The sensitivity of g s to VPD is described by Root Mean Square Error (RMSE, σ, n = 9)
Molecular mechanisms of stomatal closure in response to . . . Vapour pressure deficit (VPD), the difference between the saturation and actual air vapour pressures, indicates the level of atmospheric drought and evaporative pressure on plants VPD increases during climate change due to changes in air temperature and relative humidity
