1.Water in nature: its importance and water cycle. Physical properties of water which are important for plant water relations (hydrogen bonds, chemical potential of water, cohesion, adhesion).
2. Water in plants, relative water content, water potential and its components (osmotic, pressure, matric, and gravitational potentials) and their role at the level of a cell and the whole plant.
3. Water and solute transport at the cellular level, permeability, reflection coefficient, aquaporins.
4. Water uptake by the roots, radial water transport through apoplast and symplast, longitudinal transport, root pressure, guttation. Liquid water uptake by the shoot.
5. Water transport in the xylem, the cohesion theory, occurrence of xylem embolism and refilling the embolized vessels.
6. Transpiration as a diffusion of water vapour. Water vapour transport through the boundary layer of the air, cuticle, stomata and intercellular spaces.
7. The importance of stomatal and cuticular transpiration. Energetic balance of the leaf.
8. Structure and ultrastructure of the stomata, mechanisms of the opening and closing of stomata.
9. The effects of both external and internal factors on stomata opening. Simultaneous action of more than one factor. Feedback loops. Acclimation to growth conditions.
10. Regulation of the transpiration and photosynthetic rates by stomatal conductance, water use efficiency.
11. The development of water deficit and its influence on basic physiological processes. Stomatal and non-stomatal limitation to photosynthesis.
12. Stress proteins, drought resistance of plants, plant resistance to salinity. |
