Abstract
Due to overexploitation and clearing of natural forests, many important and valuable timber species had been forfeited. Decreasing number of timber species require immediate attentions to sustain natural forest and timber products as a source of country earnings. Kapur bukit (Dryobalanops beccarii Dyer) is one of the potential species for large scale plantation. The objectives of this study were to establish effective and proper cutting methods in order to produce planting materials. Secondly, this project examines the most suitable plant growth regulators to enhance rooting. At the same time, the incidence of plagiotropism was observed. Through plant propagation technique of cutting, the most suitable plant growth regulators of Indole-3-butryic acid (BA) to enhance rooting were examined. Four assigned treatments; no treatment or control, 2 g/L of BA, 5g/L of IBA and commercial hormone of SADEX were used. Two positions of branch and stem cuttings were examined to observe the incidence of plagiotropism in Dipterocarpaceae. Overall, two trials were conducted to get more reliable data. Results showed that this species is very hard to root. Lower concentration of BA in the first trial of 2 mg/L and 5 mg/L were able to produce roots whereas in higher concentration, cuttings failed to form root within given period. Due to time constraint, the incidence of plagiotropism was not observed. Results obtained from these studies showed that further research is required to support these findings.
