Peltophorum dubium (Sprengel) Taubert is a forest tree that is native to Brazil and that has ecological and economic importance. Preliminary studies on the micropropagation of the species covered aspects of the in vitro establishment and multiplication and indicated that it has potential for this type of asexual propagation. The present study evaluated the in vitro rhizogenesis of P. dubium shoots via micropropagation on different culture media with different concentrations of sucrose, auxin, and agar and analyzed the subsequent in vitro acclimatization of the plantlets. Rhizogenesis was evaluated on half-strength Woody Plant Medium nutritive medium that contained 30 cm3 vermiculite and different concentrations of sucrose (0, 15, or 30 g·L1), the auxin indole-3-butyric acid (0 or 10 μM), and agar (0 or 7 g·L-1). Rooting shoots were transferred to a substrate for in vitro acclimatization. The best medium both for rhizogenesis (producing roots in 44.43% of cases); and for in vitro acclimatization contained 7 g·L-1 agar but no sucrose or auxin. The addition of agar to the medium in the absence of sucrose and indole-3-butyric acid resulted in a better quality radicular system in micropropagated shoots of P. dubium and with a satisfactory survival rate of the plantlets during in vitro acclimatization.
