Fig. 7From: Monitoring of plant water uptake by measuring root dielectric properties on a fine timescale: diurnal changes and response to leaf excisiona Changes in relative root electrical conductance (GR) during the first eight measurement hours for maize, cucumber and pea in the leaf excision (“LE”) experiment. Relative GR is the ratio of measured GR to the corresponding initial value (t = 0.5 h). b Linear relationships between electrical conductance loss (ΔGR) and transpiration loss (ΔT) for the three species. Regressions were significant at the p < 0.01 level. See the text for detailsBack to article page
