• Normally tea bushes are established within a month after planting. Within a period of 12 to 18 months they reach a height of 60 – 75 cm (Field plucking stage) and after this stage pruning is taken up.
  • Pruning operations for bush formation
  • Water participates directly in many metabolic processes. Inter-conversion of carbohydrates and organic acids depend upon hydrolysis and condensation reactions.
  • Water increases the rate of respiration. Seeds respire fast in the presence of water.
  • Water is the source of hydrogen atom for the reduction of CO2 in the reaction of photosynthesis.
  • Water acts as a solvent and acts as a carrier for many substance. It forms the medium in which several reactions take place.
  • Water present in the vacuoles helps in maintaining the turgidity of the cells which is a must for proper activities of life and to maintain the form and structure.
  • Water helps in translocation of solutes.
  • In tropical plants, water plays a very important role of thermal regulation against high temperature.
  • The elongation phase of cell growth depends on absorption of water.
