Penelitian ini mempunyai tujuan untuk mengetahui pengaruh perlakuan jenis media, tunas apikal dan konaentrasi Rootone-F terhadap rhizogenesis adventif stek pucuk jati (Thctona. gmndis L.f.) yang diukur dari panjang aksr, jnmlah aksr, prosentase peraksran dan prosentase pembentukan kalus. Penelitian dilalolanakan di rum.ah kaca Faku.ltas Kehutanan UGM, selama tujuh bulan dengan. menggu.nakan percobaan Split­Split Plot yang disusun da]am Rancangan Acak Kelompok dengan delapan ulangan.

The experiment was conducted to observe the effect of media types, shoot tip and Rootone-F concentration on adventitious rhizogenesis paramaters of teak (Tectona grandJ,.s L. f.) top cutting, namely : length of root, number of roots, percentage of rooting and percentage of callusing. The experiment was conducted in the green house of Faculty of Forestry Oadjah Mada University for 7 months. The experiment design was Split-Split Plot in Completely Randomized Design with eight replications. Media types as main plot comprising of 3 types : soil (M 1), sand (M2) and vermiculit (M3), shoot tip as sub-plot comprising of 2 kinds: tipped top cutting (Tl) and untipped top cutting (T2), Rootone­F concentration as sub-sub plot comprising of 4 levels : Control (RO), 100 ppm (Rl), 300 ppm (R2), 500 ppm (R3). The result showed that media types highly significant affected length of root and non sigrdfi????ant to the other paramaters. Soil medium (Ml) had the longest root. Shoot tip showed highly significant affected percentage of rooting and callusing and signi1foant affected. length of root and number of roots Untipped top cutting (T2) significantly could increase length· of root, number of roots and percentage callusing meanwhile tipped top cutting (Tl) ·significantly could increase percentage of rooting. Rootone-F concentration highly significant affected length of root .and number of roots and non significant affected percentage of rooting and callusing. Length of root and number of roots increased as the Rootone-F concentration treatment increase. The highest amounts and the longest root was achieved on 500 ppm Rootone-F but the best concentration of Rootone-F had not been obtained yet. Interaction combination treatment showed non significant.
