RATIONALE FOR STRONG RESEARCH INTEREST IN TEAK

ONE OF THE MOST SOUGHT AFTER TIMBERS IN THE WORLD!Approximately 3 million cubic metres of Teak is harvested globallyper annum from both native forests and plantations. Natural forestsof Teak do not meet current or future demands and will soon bebanned totally. A rising trend towards large-scaled Teak plantation

establishment in Australia, Latin American countries and Africa isnow observed.

Straightness of bole with small branches (minimalknots), fast growth, and high heartwood to sapwoodratio, are characteristics of the selected clones, Solomon

Island Origin, under Sabahs growing conditions. Meanannual growth of 2.5-3 cm in diameter and 3-4m in heightcan be expected.

1. Optimal protocol developed- High multiplication rate, simple and cost-efficient

2. Possibility of introducing and mass multiplying any selectedgenotypes (clones) regardless of ortet age

- Ensure homogenous growth for plantation establishment

3. Allows the delivery of plants to overseas markets- Benefit of a phytosanitary certification overcoming quarantine

constraints
