Course review:
1. Parameters of water status (RWC, water potential and its components). Estimation of water content from reflectance spectra. Transpiration and water transport (gravimetry, potometry, gasometry, rate of xylem transport. Measurement of ion leakage through membranes. 2. Photosynthetically active radiation (PAR): sources, spectra, units, measurement. PAR in canopy, LAI. Optical phenomena in leaf (reflectance, transmittance). Analytical and non-destructive measurement of pigment content in plants. Chloroplast movement. Optical indexes used in plant physiology. 3. Plant description. Structure of photosynthetic apparatus of higher plants (leaf, chloroplast, thylakoid membranes, pigment-protein complexes). 4. Chlorophyll fluorescence, fluorescence induction (definition, properties, fluorimeters, measurement, parameters). Remote-sensing. Phenotyping. 5. Photosynthetic oxygen evolution. Rate of CO2 assimilation (IRGA, gasometric systems, parameters). Light- and CO2-curves of photosynthesis. 6. Introduction to plant electrophysiology. Electrochemical potential. Nernst´s equation. Resting membrane potential, action and variation potential. Measurement of electric signals in plants: surface and intracellular methods, aphid-method, patch-clamp.
