The temperature gradient as the driving force of water and solutions flow in the root
- 1 Institute of Ecobiology of the Slovak Academy of Sciences, Bratislava, Czechoslovakia
The examination of thermoosmosis in the maize primary root tissue has shown that under the rising temperature gradient (gradT) all flows are declining, which continue also under the gradT levelling between compartments. The permeability coefficients are declining similarly as flows. The reflection coefficient during the rising gradT declines, but it rises during the gradT levelling between compartments. These phenomena depend on the plant age and concentration of the bathing solution.
