Abstract:The method describes improvement in adventitious rhizogenesis in Bambusa vulgaris var. green. The sturdy mini cuttings collected from one-year-old pollarded culms and grouped in three diameter class, viz. 0-0.5 cm, 0.5-1.0 cm and 1.0-1.5 cm were treated with 100 ppm IBA and control and planted on germination bed of shadehouse in June 2014. Out of different diameter classes, the cuttings in 0.5-1.0 cm diameter class produced a maximum of 83% rhizogenesis with maximum root length (31.63 cm), root number (16.83) and tiller height (20.96 cm). However, the maximum tiller number (1.8) was obtained in 1.0-1.5 cm diameter class. However, the interaction study showed maximum rhizogenesis (100%), root length (32.76 cm), root number (17.33) in diameter class (0.5-1.0 cm) in control, which was significantly higher than the treatment (100 ppm IBA) and in another diameter class viz. 0-0.5 cm and 1.01.5 cm. The findings of the study suggest augmenting adventitious rhizogenesis using mini cuttings (0.5- 1.0 cm diameter) of Bambusa vulgaris without any hormone treatment in the month of June.
