Sažetak
Xylem is modelled as the closed system coupled to the root and phloem via semi-permeable membranes. The importance of the fixed volume of the xylem in the osmotic process between xylem and phloem is analysed. It is shown that negative pressure, a concept accepted as a driving force for the upward xylem water transport in many scientific discussions [1, 2], is closely related to this process. It is shown that there is a self-consistency between decrease of the pressure in the xylem and increase of the concentration of the sugar in phloem, respectively, in dependence of the height.
