This PDF file includes:

  • fig. S1. Ψmdl depending on Ψpd in different V. vinifera varieties and under environmental conditions.
  • fig. S2. Correlations between Ψpd and minimum Ψleafmin; that is, average value of three lowest Ψmdl per 0.1 MPa wide class of Ψpd) in different V. vinifera varieties (Grenache and Syrah) and under environmental conditions (field and greenhouse).
  • fig. S3. Midmorning stomatal conductance measured on individual leaves, depending on predawn leaf water potential Ψpdl in four grapevine varieties (V. vinifera cv.Grenache, blue; V. vinifera cv. Syrah, red; 110 Richter, green; V. riparia, pink) during a drydown experiment in greenhouse.
  • fig. S4. Whole-plant stomatal conductance under saturating light, depending on vapor pressure deficit, in four grapevine varieties.
  • fig. S5. Percent stem loss of hydraulic conductivity depending on applied pressure in V. vinifera cv. Syrah and Grenache grafted on different rootstocks (V. riparia, SO4, and 110 Richter) after growth cessation (September), using a dedicated 1-m-diameter Cavitron device (Cavi-1000).
  • fig. S6. Whole-plant stomatal conductance Gs depending on leaf-scale stomatal conductance gs, measured at the same moment (±1 hour).
  • fig. S7. Ψpd depending on RWC in four grapevine varieties (V. vinifera cv. Grenache and Syrah, 110 Richter, and V. riparia) during a drydown experiment in a greenhouse.
