BOT 4590 Enviro Stress Physiology

Environmental Factors Result In Massive Annual Global Crop Yield Losses. Research Focused On An Understanding Of Plant Environmental Stress Tolerance Mechanisms Has The Potential To Greatly Benefit World Agriculture. These Mechanisms Are Complex, And Their Elucidation Will Require A Long-term , Multi-disciplinary Research Effort. The Effects Of Environmental Stresses On Plants Growth, Development And Yield, And The Physiological And Physical Mechanism Used By Plants To Tolerate These Stresses Are Discussed With Emphasis On Low Temperature,wind And Water Stresses. Fundamental Plants Processes Including Membrane Transport, Cell Elongation, Stomatal Control, Osmotic Adjustment, Sap Flow, Photosynthesis And The Role Of Growth Regulators Are Discussed In Relation To Their Response To Environmental Stress
