Languages of instruction


Definition of the term stress in plants.
Perception and transduction of stress signals.
Plant responses to stress conditions: mechanisms of stress resistance (stress avoidance, stress tolerance and stress acclimation).
Major types of abiotic stress and their interactions with the physiological responses of plants:
water stress (drought, flooding)
radiation stress (excess light, UV radiation)
basics of plant nutrition, poor soils
low and high temperature extremes
Acid soils, alkaline soils, salinity, heavy metals
atmospheric pollutants (oxides of nitrogen and sulphur, ozone...)
Poor soils, heavy metals

Previous knowledge expected

Basic knowledge of plant structure and functions

Objective (expected results of study and acquired competences)

Students who have successfully passed the lecture, are able to recognize that stress in plants is induced by unfavourable environmental conditions. The knowledge of the adverse effects of the major types of abiotic stress on metabolism and on other physiological processes that control growth, development and productivity of plants, enables the students to assess losses in crop yield that can be attributed to stress. Moreover, the students have the ability to analyze the mechanisms of stress resistance which plants have developed to cope with stress conditions in order to prevent injury and maintain life functions.
