Introduction: the position of water relations in the framework of plant physiology, their importance for plants.

The pathway of water from the soil to the atmosphere: transport through parenchymas and in the far-distance transport system; transport resistances; cavitation and embolization; resistances and fluxes in the gas phase.

The state of water, its units and their determination: chemical potential and total water potential; partial potentials in the continuum; partial potentials adjusting the correct values for total water potential.

Measuring total water potential and its partial components: instruments and methodological problems.

Physiological effects of changes in the water status; resistance against water stress.

Objective (expected results of study and acquired competences)

Understanding the pathways of water in the soil-plant-atmosphere continuum and changes in the energy status due to transport processes; understanding the necessary instruments and measurement techniques.
