Course abstract

The course enable the students to understand the influence of various environmental factors on plant growth, yield formation, possibilities to influence yield quality, clarify the influence of stressors’ damage on physiological processes in plants, possibilities to reduce these damage and repair mechanisms.

Learning outcomes and their assessment

Master students gain a knowledge of the impact of environmental conditions on plant growth and development. Students are able to determine the most important physiological parameters of plants and the influence of limiting external environmental conditions.
Students are able to evaluate the factors affecting and limiting the ontogenesis of plants, understand their impact on crops. They area able to organize experiments related to the study of environmental conditions.
Students can evaluate factors effecting accumulation, transformation and degradation of organic matter, are competent to analyse the effect of different factors on the plants.
