Languages of instruction


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)

An in-depth understanding of experimental plant physiology. Participants acquire not only a broad knowledge of methods and instruments used to assess stress resistance in plants, but also the ability to point out the limitations and shortcomings of these approaches. After the course, students have experience in using scientific instruments and methods to acquire eco-physiological data and also in how to analyze and interpret complex physiological data sets.
