N2 - Longitudinal resistances of excised roots (Rr), isolated steles (Rstels), and cortical cylinders (Roortex) of maize seedlings were measured as a function of the KCl concentration in the bathing medium and as a function of root length. The resistances were found to be proportional to root length beyond 1 cm from the root tip. Rr was independent, while Rstels and Roortex showed a marked dependence on [KCl]. The results are analysed in terms of a passive network of parallel resistances. It is concluded that the symplast is the major determinant of the longitudinal root resistance.
