One of the alternative method to produce large number and uniform mangosteen seedlings inshort period can be done using in vitro culture technique. The purpose of this research was to determine the optimal concentration of BAP and honey in inducing shoot from of mangosteen explants from seed that had been divided into four parts and also to determine the best combination to induce mangosteen shoot uisngin vitromethod. The research was conducted at Integrated Biology Laboratory Department of Biologi, Faculty of Mathematics and Natural Sciences, Riau University from January until April 2015. This research used a Completely Randomized Design (CRD) with the concentration of BAP (3; 7 mg/l) and honey (3; 6; 9 ml/l), or in combination on MS medium with 5 replications.The result showed that the treatment on medium supplemented with each BAP and honeyor in combination gave the highest percentage of explant growthand shoot formation (100%)while the medium supplement with 7 mg/l BAP + 6 ml/l honey only need six days for shoot inductionenBenzylaminopurinHoneyIn vitroShootinductionMangosteen (Garcinia mangostana L.)student Paper Post Degree
