Outline of Final Research Achievements

Growth characteristics (tree height and stem diameter) and wood density were measured on various teak (Tectona grandis) plantations in Peninsular Malaysia where is estimated as unsuitable climate zone for teak growth. A total of six teak plantations (from 14 to 46 years old) were selected from six States in Peninsular Malaysia. Mean stem diameter at breast height (DBH), mean tree heights, and the dominant tree height in the study site (DTH) varied from 18.0 to 26.4 cm, from 12.0 to 21.2m, and from 16.9 to 27.3m, respectively. These values were within the range of those in Thailand. Wood density of study sites was 0.52 to 0.59g cm-3 and the values were also similar in Thailand. These results indicated that growth characteristics and wood density of teak plantations in Peninsular Malay was comparable to those in Thailand despite there were different climate characteristics.
