A review on the Malaysian Aquilaria species in Karas Plantation and Agarwood Production
Mohd Fauzi Elias
Malaysia is one of the countries which is rich in its flora and fauna bio-diversity. Malaysian forest products have been exploited since ancient times for its high economic values. One of these high economic value products is agarwood. Thymelaeacea is one medium-size family tree where it is estimated to consist of 50 genera and 900 species of which many can be found in Africa, Australia and Asia. Most species of Aquilaria in Thymelaeaceae family produced agarwood or ‘gaharu’. Aquilaria malaccensis is a species of the highest recorded number of planting by karas tree farmers and known as the primary producer of agarwood in Malaysia. Agarwood is non timber forest product it is one of the precious wood on earth and prized for its rich and wonderful fragrance. Agarwood is formed due to the phathological process as respond to fungal infection or chemically stimulated. This paper seek to understand in general the type of karas trees species most favoured by karas farmers and to know what.....

Effect of different chemical formulation on agarwood (Aquilaria malaccensis) resin weight
Mohd Fauzi Elias
Agarwood is described as fragrance, smelling wood that is usually derived from the trunk of genus Aquilaria The objective of this study was to develop and evaluate four chemical-based inoculants to induce karas tree to form agarwood resin. Four chemical inoculants were applied into 6 years old karas tree (Aquilaria malaccensis) plantations in Slim River, Perak, Malaysia using dripping techniques. The inoculant used were labelled as A, B, C and D. Commercial inoculant was also used for comparison purposes and labelled as K while a healthy tree, act as control was labelled as N. After four months of inoculation, these samples were cut down and discoloured tissue samples were collected. Solvent extraction method using dichloromethane (DCM) was carried out to obtain the resin crude extract from plant tissues of the samples. All chemical formulation used were succesfully stimulated sample trees to produce resin. Inoculant B produced the highest crude extract recovery (5.49%) compared to ino.....

Potensi inokulan terpilih terhadap penghasilan resin oleh Aquilaria malaccensis Lam
Mohd Fauzi Elias
Kajian  ini  berkenaan  potensi   inokulan  terpilih   terhadap  penghasilan   resin  oleh Aquilaria malaccensis  Lam (pokok karas). Objektif utama penyelidikan  ialah untuk menghasilkan    inokulan   bagi   mengaruh   pokok   karas   untuk   menghasilkan   resin. Kawasan kajian terletak  di ladang karas Kampung Tambak, Slim River, Perak yang melibatkan  sebanyak  36  pokok  karas   berusia  enam  tahun.  Inokulan  yang  telah dihasilkan dilabel sebagai A, B, C dan D, manakala  inokulan berlabel K merupakan inokulan komersil. Kumpulan kawalan dilabelkan sebagai N, merupakan  pokok sihat tanpa rawatan. Setiap pokok telah disuntik sebanyak 80 ml inokulan. Tempoh masa kajian   adalah  selama  12  bulan.  Penebangan  pokok  untuk  setiap  kumpulan  bagi mendapatkan resin yang  terbentuk adalah pada setiap sela masa empat bulan. Pelarut organik;  iaitu  heksana.   diklorometana  dan  metanol  telah  digunakan  untuk .....
