- Figure 1.
Experimental set-up. In the loam treatment, both sensors were placed like sensor 1 in the diagram, i.e., in contact with the root ball. In the lava treatment, sensor 1 was installed as in the loam treatment, and sensor 2 was placed 2 cm away from the root ball.
- Figure 2.
Predawn leaf water potential (PDWP) as a function of soil water potential (SWP) for the loam treatment (left; adjusted R2 = 0.73, p < 2e − 16, DF = 214) and the lava treatment (right; adjusted R2 = 0.73, p < 2.2e − 16, DF = 164). Points are daily means of PDWP and SWP measurements per pot. Continuous line: line of best fit; gray area: confidence interval (95% confidence level). The dashed lines confine the 95% prediction interval.
- Figure 3.
Correlations between soil and leaf water potential for individual containers in the loam treatment (left) and the lava treatment (right). Circles and dashed line: sensor 1; crosses and solid line: sensor 2. Gray area: 95% confidence interval. Selected pots.
