Abstract

An experiment was undertaken to standardize the vegetative propagation in Oroxylum indicum (L.) Vent. at College of Horticulture, Mudigere during 2016–17. Hardwood and limb cuttings were used for the study. The cuttings were treated with different hormonal treatments like NAA, IBA and their combinations. Among the different treatments, hardwood cuttings treated with NAA 200 ppm+IBA 3000 ppm showed maximum sprouting (86.67%), number of shoots (7.05), shoot length (10.97 cm), number of leaves (28.33), rooting percentage (60.33), number of roots per rooted cutting (43.30) and average root length (31.53 cm). Findings of this study can be used for large scale propagation of this highly useful medicinal tree species for their sustainable use.
