Mathematical modeling of measuring the hydraulic conductivity of roots by the relaxation method

Biofizika. 2011. No. 56(3). P. 483-489.

The continuum model of radial mass transfer in plant roots we developed previously is used for processing the nonstationary experiments aimed at the determination of the root hydraulic conductivity. It is shown that in contrast to compartmental models our model allows to describe the observed shape of the relaxation curve and to obtain segments with different relaxation times. It is found that for correctly determining the hydraulic conductivity the data processing method should be modified. A method is also proposed for estimating the extracellular to intracellular conductivity ratio.
