Abstract


Ubah merah (Syzygium lineatum (DC) Merr) is one of indigenous tree type. Its population have been decreased with the increase of peat swamp forest degradation as the effect of land conversion and forest fire. The seed multiplication technique of S.lineatum vegetatively can be done with shoot cutting. This research was aimed to get the composition of root stimulants with suitable of growth media for growth of S.lineatum shoot cutting. The experiment of this research used split plot design with basic design of completely randomized design (CRD). The treatment as main plot was growth media cocopeat (M1) and cocopeat + husk char 2:1(M2) and as sub plot was root stimulants control (Z1) rootone-F 3.5 g (Z2) and wood vinegar 4% (Z3) with five replications in each treatments combination. The dependent variables consisted of primary root total, secondary root total, primary root length, shoot length, leaf total, and percentage of living. The results showed that the root stimulants and growth media were not significantly affect on growth of S.lineatum shoot cutting. The data has a tendency that root stimulants wood venegar and growth media have good affect for growth of S.lineatum shoot cutting, with the percentage of living was 93%.
