AMELIORATION CHEMICAL & PHYSICAL CORRECTIONS
ORCHARD DESIGN DESIGN TO COMPLIMENT VARIATION
13 WATER STRESS • Effects of water stress on plant – If water not easily available for root uptake – ABA produced in roots – Transported to the leaves – Osmotic pressure in the guard cells drop – Stomata close – Water loss decreases BUT no CO 2 enters plant – No photosynthesis – Leaf temperature increases – CO 2 assimilation, protein synthesis & metabolism slows down – Cell division decreases – Cell growth decreases – Smaller fruit size & poorer quality
VARIATION & IRRIGATION IRRIGATION BREAKS More water less regularly Less water more regularly
