Fig. 5. — Relationships between capacitance (C, nF) and fresh mass (g) (panel A) and the sum of cross-sectional areas at the solution surface (A, mm²) (panel B) for 48 seminal roots (● ) and 103 nodal roots (◯) after excision from eight plants. The roots were submerged with 5mm between solution surface and plant electrode (see Fig. 3A). There was no significant correlation between C and fresh mass for seminal roots or nodal roots. Linear regressions for the relationships between C and A were C = (121±4.4) × A (R ² = 0.806, P < 0.001) for seminal roots and C = (28.2±0.88) × A (R ² = 0.771, P < 0.001) for nodal roots (mean ± SE). Data represent the mean ± SD of three repeated measurements.
