Table 1 Shoot hydraulic conductance (Kshoot) (kg H2O s−1 MPa−1), standard deviation (SD), and R2 response of cotton cultivars in Experiment 1: (38 °C, vapor pressure deficit (VPD) > 3 kPa) and Experiment 2: (32 °C, VPD = 1–1.5 kPa) in controlled environments

From: Cotton stomatal closure under varying temperature and vapor pressure deficit, correlation with the hydraulic conductance trait
