Fig. 11. — The relationships between capacitance and the reciprocal of cumulative distance/area (equation 3) for a whole root system (● ), a seminal root (▲) and an unbranched nodal root (■). The linear regression coefficients for the relationship were C = 42.0 (R ² = 0.964, n = 14) for the whole root system, C = 44.4 (R ² = 0.913, n = 10) for the seminal root, and C = 18.5 (R ² = 0.919, n = 8) for the nodal root. Values were calculated from data presented in Fig. 8 (where A is in mm² and ∆d is in cm) and represent the mean ± SD of three repeated measurements.
