Objective of the study

• To produce a numerous and low cost planting
  material stocks in aim to restore the degraded
  forest landscape
• Specific objective for Ravensara aromatica
• To ensure that chemotypes identified through
  chemical analyses of essential oil will be
  maintained in clonal trees.
• To respect the market request of homogeneity of
  essential oil composition to win added value.

3
Material and method

• 200 stem cuttings, 2 trees for every 5 chemical
  patterns of Ravensara aromatica harvested in 4
  natural forests (Ampasina, Didy, Anosibe anAla,
  Raboana)
• Avalaible number of cuttings from other available
  native species trees met in forest.
• Simple technic easily transfered to local
  population (leafy stem cutting 7-10 cm
  length,7-10 mm diameter, hormone AIB
  1(optional), raised in plastic bag on mixture
  2/3 compos-1/3 river sand, raised on chassis,
  daily morning watered)
