Uptake8
  • Water stress occurs in response to atmospheric and soil water availability when the transpiration rate exceeds the rate of water uptake by the roots and cells lose turgor pressure. (wikipedia.org)
  • By maintaining appropriate VPD levels, you can effectively manage the transpiration and nutrient uptake of your plants. (growsensor.co)
  • How does VPD affect plant transpiration and nutrient uptake? (growsensor.co)
  • Maintaining the appropriate VPD levels is crucial for plant transpiration and nutrient uptake. (growsensor.co)
  • Water use by vegetation is controlled by the water uptake by roots, the transfer of liquid water through plants and vapour loss from the leaf surfaces by the opening and closure of the stomata (Roberts, 2000) i.e. transpiration. (uky.edu)
  • Stomata, the small pores found on the underside of leaves, play a crucial role in CO2 uptake and transpiration. (codechi.de)

Abscisic acid5
  • Under the water deficit environment, plants synthesize a phytohormone, abscisic acid, which triggers stomatal closure to prevent transpirational water loss ( Beardsell and Cohen, 1975 ). (ashs.org)
