The subject comprises biochemical and physiological aspects of
plant resistance to environmental (abiotic and biotic) factors. The
special attention is paid to water, salinity, radiation, temperature
and contamination stresses. The defence mechanism of plants
against pathogens and pests (particularly insects) is presented as
well as some problems of allelopathy.
1. Definition of stress, general reactions of plants to abiotic and
biotic stresses, mechanisms of defense and tolerance to
osmotic (draught & salinity), thermal, radiation, oxidative and
environmental contamination stresses 2 hrs
2. General characteristics of plant resistance to pathogens.
Passive and active resistance, induced mechanism of
resistance, specific resistance, hypersensitivity reaction,
structural barriers, phytoalexins, PR proteins. 4 hrs
3. Physiological aspects of allelopathy 2 hrs
4. Plant resistance to pests, biochemical interaction between plant
and insects 2 hrs
1. Determination of proline in plant tissue, subjected to osmotic
stress 3 hrs
2. Determination of phytoalexin (isocoumarine) in carrot roots
infested by carrot fly. 4 hrs intopic 3
3. Measurement of lipid-protein membrane permeability in leaves
of various plant species resulted from low temperature
treatment 3 hrs
