Abstract
Abstract Alternanthera reineckii is an aquatic plant that is used as an aquascape plant. This commodity is in great demand so that its needs is continue to increase. To meet market demand, technology that can produce large quantities of seedlings in a short time is needed. In vitro propagation is a technology that can be used to produce uniform plants with a relatively high level of multiplication. The aim of this study was to obtain the appropriate type and concentration of auxin for the in vitro induction of Alternanthera reineckii roots. In this study, a factorial completely randomized design was used. The first factor is the type of auxin (IBA, NAA and IAA) and the second factor is the concentration of auxin (0, 0.5, 1.0 and 1.5 mg / l) with 10 replications. The results showed that the best auxin for Alternanthera reineckii root induction was IBA at a concentration of 1 mg/l.
