A study on vegetative propagation of Aquilaria microcarpa Baill. (Gaharu) by using stem and branch cuttings method under different stock ages plant of Aquilaria microcarpa and Plant Growth Regulators (PGR) was carried out at the Green house, East Campus of University Malaysia Sarawak (UNIMAS). The objectives of the study were (i) to examine the effect of stock plant age on rooting of cuttings, and (ii) to examine the effect of PGR on rooting. Aquilaria sp. has high commercial value in the production of incense, perfume and medicines. Due to the high demand of Aquilaria sp., it has been over exploited in the natural forests. The populations of Aquilaria sp. are decreasing rapidly and become endangered through uncontrolled harvesting. Vegetative propagation through stem cuttings is an effective way to control the number of Aquilaria sp.populations. In the study, four different ages of stock plant were used. They are i) 6 months old coppice from two years old seedling, ii) two years old potted seedlings, iii) three years old coppice from 8 years old stock plant, and iv) 4 years old of seedling. 0 mg/L, 50 mg/L, 100 mg/L and 200 mg/L of Indole-3-butyric acid (IBA) were used to examine which concentration is more effective to enhance rooting in stems and branch cuttings. 2 years old potted seedlings of cuttings was the best age of plant stock to produce highest rooting success percentage, number of root formed, and rooting length. 6 months old coppice from 2 years old seedlings of cuttings was the best ages of plant stock to produce the highest shoot percentage, number of shoots produced, and shoot length.Cutting treated with 0 mg/L of IBA was the best PGR to produce highest rooting success, number of root formed, root length, shoot percentage and number of shoot produced.
