Abstract

A protocol was developed for in vitro rooting of Dendrobium chrysotoxum Lindl. cv. Golden Boy where different auxin sources [indole-3-butyric acid (IBA), -naphthalene acetic acid (NAA) and indole-3-acetic acid (IAA)] were evaluated in the presence of activated charcoal (AC). A combination of 0.2 mg•dm–3 IBA plus 2 g•dm–3 AC in MS proved excellent in terms of earliness in root induction, root number, and length as well as response to rooting of in vitro generated microshoots. IBA performance was better than NAA or IAA in presence of AC for root induction and elongation.
