Course abstract | |
Plant growth and development. Plant hormones and growth regulation. Photoperiodism and physiology of flowering processes. Dormancy. Plant stress and adaptation to environmental conditions. Sick plant physiology. Plant immunity. Seed development, ripening, dormancy and germination. Physiological processes of yield formation of different groups of agricultural crops. | |
Learning outcomes and their assessment | |
Students obtain knowledge about plant growth and development, physiological processes in plants, effects of internal and environmental factors on plants and yield formation.
Students are able to determine main physiological parameters of plants. Students can assess plant growth and development and affecting and limiting plant ontogenesis factors. |
