Fig. 1From: Monitoring of plant water uptake by measuring root dielectric properties on a fine timescale: diurnal changes and response to leaf excisiona Representation of plant root as a cylindrical capacitor, according to Dalton [6] and Ellis et al. [13]. In the equation for the electrical capacitance C, ε and A are the permittivity and surface area of the root tissue, respectively, r1 is the xylem radius and r2 is the rhizodermis radius. b Electrical equivalent network of the root system, according to Dietrich et al. [9] and Ehosioke et al. [1]. c Scheme for root dielectric measurement on a fine timescale with a software-controlled LCR meter and an asymmetric cycler, as used in the present studyBack to article page
