Fig. 5. — Midday leaf g_d, E_d, A and C_i in response to VPD (n = 4) of vines grown in either cool or warm soil. At the time of measurement, root-zone temperature of the warm treatment was 20·3 ± 0·9 °C and of the cool treatment was 13·3 ± 0·7 °C (P < 0·001). Soil moisture was not different between the treatments (F-test, P = 0·50) and averaged 16·8 ± 0·5 %. The intercepts and slopes of the regressions for the cool and warm cohorts are different from each other for E_d (P < 0·001), but only the intercept for g_d (P < 0·001) and A (P < 0·001). A non-linear curve was fitted to the C_i data of the cool root-zone temperature treatment (P < 0·001).
