Leafy stem cuttings of Kemunting (Rhodomyrtus tomentosa) were collected from matured plants located at nine locations to investigate for variation in rooting ability, together with the effects of types of cutting (softwood, semi-hardwood and hardwood) and indole-3-butyric acid (IBA) concentrations (0, 800, 1600, 2400, 3200 mg l-1). The effect of locations and types of cutting were significant for all studied parameters while IBA treatment was significant only for rooting percentage. There were interactive effects of location п‚ґ types of cutting for rooting percentage, mean number of roots, mean root length, mean root dry weight, and survival rate. The highest and lowest rooting percentages with respect to locations were recorded by cuttings from Jeram Pasu, Kelantan (D-02) (58.7%) and Ayer Hitam, Negeri Sembilan (N-01) (10.9%) respectively. Softwood cuttings performed better in all rooting parameters compared to semi-hardwood and hardwood cuttings. The highest rooting percentage (50.9%) was obtained using softwood cuttings. This was followed by semi-hardwood (32.9%) and hardwood (7.9%) cuttings. IBA treated cuttings did not show any improvement in the rooting performance. Our results showed that softwood cuttings of R. tomentosa from Jeram Pasu, Kelantan (D-02) rooted highest.
