INDUKSI NODUL DARI EKSPLAN BIJI MANGGIS (Garcinia mangostana L.) ASAL BENGKALIS PADA MEDIA MS SECARA IN VITRO

Abstract

The nodule is one of the indirect organogenesis stages of development into shoots or roots which will then become the plant intact. Mangosteen (Garcinia mangostana L.) from Bengkalis with excellence can live in the peat soil is a tropical fruit that became one export commodity of Riau  Province. This study aimed to induce nodules from explants of mangosteen seeds (Garcinia mangostana  L.) from Bengkalis using single BAP (Benzil amino purine) and honey as well as a combination of urashige Skoog (MS) media. This study used a Randomized Block Design (RBD) using BAP (0; 5; 7 mg / L) and honey (0; 3; 6; 9 ml / L) concentrations both singly and in combination. The results of this study indicate that the highest percentage of nodules formed is found in the treatment of 7 mg / l  BAP and 7 mg / l BAP + 6 ml / l honey on MS media at 100%. The fastest time of the nodules appear contained in the treatment of 5 mg / l BAP + 9 ml / l of honey was 5.6 days after planting. The highest number of nodules at 40 days after the treatment of 7 mg / l BAP in the MS medium was 28.0 nodules.
