ABSTRACT
The family Musaceae comprises of four sections among which Rhodochlamysis one. The plants of this section are commonly known as ornamental banana, which occur wild in north east India. To exploit their ornamental value on a commercial scale, planting material becomes a limiting factor due to poor suckering ability of these plants.Invitro propagation can be tried, but it is not easily affordable by a normal farmer/gardner. Hence, macro propagation was tried to see the practicability in using it for large scale multiplication. Banana has strong apical dominance, which when suppressed will give rise to many side suckers. This principle was used in macro propagation. Musa laterita was used in the present study. It is commonly known as Bronze banana, because of its brightly coloured flower, which is the colour of laterite soil. The roots of this plant are rhizomatous and give rise to suckers at intervals. The composted saw dust was used as initiation medium. Among the three treatments tried, decapitation of rhizome and treatment with 0.04% BAPhas shown good results with high number of buds and high per cent of egeneration
