FIGURE 2

Mid-day stem water potentials (SWP) monitored every 2 weeks during the growing season (A) and seasonal integrals of the SWP (siSWP, B) of field grown Merlot/C3309 grapevines subjected to different irrigation amounts (FI, Full Irrigated; HI, Half Irrigated), AMF inoculation (I, inoculated; NI, non-inoculated), and their combinations. Values represent means ± SE (n = 4) separated by Kenward–Roger method and Tukey’s p-value adjustment (P ≤ 0.05). At each time point, different letters indicate significant differences as affected by Irrigation amount, I, AMF inoculation, M and their interaction (I × M) according to the linear mixed-effect model. ns and * indicate non-significance and significance at 5% probability levels, respectively.
