Stress concepts. Different resistance strategies (tolerance, avoidance) followed by plants. Description and presentation of techniques and instruments to measure essential parameters (e.g. total water potential and its components osmotic potential and pressure potential), stomatal conductance, chlorophyll fluorescence, xylem hydraulic conductivity. Water flow through the soil-plant-atmosphere continuum. Stress-induced cavitation and embolism in the conducting elements of (secondary) xylem. Measurement of vulnerability curves with the acoustic method and the hydraulic method. Comparison of responses found in stressed and non-stressed variants.

The course´s topics may be modified depending on the students´ suggestions and special interest.

Objective (expected results of study and acquired competences)

Understanding the relationship between impact of abiotic stress factors (e.g. water, temperature, radiation) and different adaptation responses of plants. Application of basic methods suitable to estimate the stress resistance of plants in field and laboratory.
