Adventitious Rhizogenesis in Relation to Seasonal Variation, Size of Culm Branch Cuttings and IAA Treatment in Bamboos

Abstract

A one year study was undertaken to investigate adventitious rhizogenesis in culm branch cuttings of Bambusa vulgaris var. striata and Dendrocalamus strictus as influenced by seasonal variation. size of cuttings, IAA treatment and their all possible interactions. Adventitious rhizogenesis in both species was found to be season specific and the cutting size and lAA treatment helped in optimizing rooting behaviour during responsive warm season of the year. April x 100 ppm IAA x double/triple nodal cuttings and February x 100 ppm IAA x double nodal cuttings are recommended for large scale vegetative propagation of B. vulgaris var. striata and D. strictus, respectively.
