PENGARUH KONSENTRASI IAA DAN BAP TERHADAP PERTUMBUHAN DAN PERKEMBANGAN TANAMAN KUNIR PUTIH(Kaempferia rotunda L.) SECARA IN VITRO

The aims of this research was to examine the effect of IAA and BAP on the growth and development of kunir putih (Kaempferia rotunda L.) in vitro. The research was conducted at LaboratoryTissue Culture, Labo- The research used Factorial Completely Design with 2 factors: IAA (0, 0.5, 1.0, and 1.5 ppm) and BAP (0, 2, 4, and 6 ppm) and 3 replications. The result showed that IAA gave more fast in initially roots, increase roots number and increase the length of roots. At 1.5 ppm of IAA without BAP provided the highest roots number and fastest initially root. The increasing concentration of BAP untill 6 ppm increased shoots number and leaf number. Interaction between IAA and BAP influence only for plant heigh. At 1.5 ppm of IAA and 4 ppm of BAP gave the best performance of plantlet.
