This course covers the role of water in the plant (cell water relations, permeability, movement of water and solutes), water in soil (soil characteristics, water retention, water movement in soil), roots and root growth (roots growth, function and environmental factors affecting root growth). Absorption of water (transpiration, kinds of absorption), factors affecting water absorption (roots efficiency, water availability, soil temperature, aeration and composition of soil solute), radiation balance (solar spectrum, radiation and duration of sunshine distribution of solar radiation, net radiation, radiation balance in greenhouse, energy exchange, movement of water through plants,

transpiration (factors controlling transpiration) and water stress and plant growth.
