EFFECTS FROM PROLONGED DROUGHT ON TREES

Moisture stress on trees affects every physiological process adversely. The first response is the closure of the leaf stomata. This acts as a defense mechanism by reducing the transpiration of water. With the stomata closed, the curtailing of photosynthesis is the result, as carbon dioxide is not absorbed. The stoma is a pore, tiny leaf opening, found in the leaf and stem epidermis (many on each leaf) that is used for gaseous exchange. This reduction in photosynthesis limits the growth and production of carbohydrates (energy) which increases the trees susceptibility to insect pests and disease.

Water stress inhibits the production and translocation of essential materials in the plant, (listed below) and further contributes to the reduced growth and development.

  • ·         Carbohydrate (food) production
  • ·         Proteins
  • ·         Enzymes
  • ·         Growth regulators
  • ·         Mineral nutrients
