The growth of mangosteen (Garcinia mangostana L.) seedling is slow due to its poor root system for having a long juvenile period. To induce better root system, we applied plant growth regulator indole butyric acid (IBA) and arbuscular mycorrhizal fungi (AMF) to the seedlings and measured its growth responses. Treatment was arranged factorially (5x2) in a completely randomized design with three replicates. The first factor was 5 levels of IBA: 0 ppm, 30 ppm, 60 ppm, 90 ppm, and 120 ppm, while the second factor was AMF innoculation: without AMF and with 25 g innoculum plant. Result showed that the application of IBA up to 120 ppm was able to increase plant height, main-root length, root fresh-weight, and whole plant dry matter. The best seedling growth (represented by plant height, main-root length, and number of secondary roots) was achieved by addition of IBA in the range of 85 – 95 ppm. In compare to control, the addition of AMF increased plant height, main-root length, root fresh-weight, and percent of root infection by mycorrhizae. When IBA and AMF were combined, the response were varied, for example the number of secondary roots at IBA 0 – 90 ppm plus AMF was higher than that of without AMF, but at higher IBA concentrations the number of secondary roots were not different whether AMF was added or not.
