The Formation of Shoots in Mangosteen (Garcinia Mangostana L.) Nodules From Bengkalis, Riau in Murashige Skoog and Woody Plant Medium

Abstract

One of the mangosteen producers in Indonesia is Riau Province, Bengkalis regency to be exact. This mangosteen has some superiority, such as able to grow in peat swamp1). Nodules are cells that develop to become shoots only in proper nutrients and conditions. This study aimed to discover the response of mangosteen nodules (Garcinia mangostana L.) on MS and WPM media by adding BAP. This study used Completely Randomized Design using various concentrations of BAP and different media. The results of this study indicate that the best response on MS medium is the percentage of nodule formation at 1 mg / l BAP of 49.99%. The fastest callus appears on control and 5 mg/l BAP 17.25 and 6.75 days after planting (dap). The most significant number of nodules at 1 mg/l of BAP is 1.50 nodules. The callus texture is compact and crumbs with white and brown colour. The best response on WPM media is the percentage of formation of a nodule at 1 mg/l of BAP resulting 33.33%. The fastest shoots emerge at 1 mg / l BAP 13.25 dap. The highest number of nodules at 1 mg/l of BAP is 1.00 nodule, the highest leaf amount at 3 mg/l BAP was 6.75 sheets, and the highest shoot length at 5 mg / l BAP is 1.32 cm. The texture callus compact and crumb with white colour.
