    One of the forest crop that has high prospect to be developed as quality for strong wood is tembesu (Fagraea fragrans Roxb.). Its wood can be used for a heavy construction and home construction. The seedlings produced from seeds of tembesu in natural stands are rarely found seedlings causing problems in propagation. The aim of this research was to determine the effect of BAP and the best concentration in inducing shoots from seed tembesu explants using in vitro method. This research was conducted at the Laboratory of Integrated Biology Department of Biology Faculty of Mathematics and Natural Sciences University of Riau from December to April 2015. This research used a Completely Randomized Design (CRD) with the concentration of BAP (0; 0,5; 1; 1,5; 2; 2,5; 3; 3,5; 4 mg/l) with 5 replications. Seeds the were planted in the media WPM for 120 days. The results of this research showed the highest percentage of shoot formation is 100% contained in the control treatment. The highest number of shoots produced in treatment of 1 mg/l BAP was 5,93 shoots. The highest average of shoot length was in control treatment 3,14 cm
