Abstract
The investigation was carried out during 2017-2019 at the Tissue Culture Laboratory, Department of Horticulture, NU: SASRD, Nagaland to study the influence of different auxins in varied doses on in vitro root regeneration of Dendrobium cv. Sonia Earsakul. The different treatments used are IBA, NAA and IAA @ 0, 0.5, 1, 1.5 and 2 mgL-1 respectively. The study revealed that among the different treatments IBA @1 mg/l resulted in the longest root length (5.97 cm), longest shoot length (7.8 cm), highest survivability during primary hardening (34.30%) and secondary hardening (94.29%).
