Abstract

The objective of this study aimed to determine the concentration of Indolebutiric acid (IBA) - Kinetin combination which is suitable for root formation of jabon (Anthocephalus cadamba (Rob) Miq) by in vitro. This research is follow-up study of in vitro shoot initiation and multiplication of anthocephalus cadamba (Rob) Miq). The research was conducted at Forestry Biotechnology Laboratory, Foresty Departmen, Forestry Faculty of Tadulako University from February 2018 to August 2018. The study was arranged in a randomized complete design with added IBA and Kinetin to basic medium Murashige and Skoog in various concentration as a treatment. Five levels concentration combination of IBA + Kinetin was studied namely : H1(0,1 ppm IBA + 3 ppm Kinetin), H2(0,5 ppm IBA + 1 ppm Kinetin), H3(1,0 ppm IBA + 0,5 ppm Kinetin), H4(1,5 ppm IBA + 0,3 ppm Kinetin), H5 (2 ppm IBA + 0,1 ppm Kinetin). The result of eskperiment showed that the concentration combination of 2 ppm IBA + 0,1 ppm Kinetin can promote best root formation of Anthocephalus cadamba, which is compared the others treatment. Treatment of 0,1 ppm IBA + 3 ppm kinetin showed no response to root formation, but promote best shoot formation of Anthocephalus cadamba.
