This paper clearly shows that propagating bamboos from material other than seed is possible. Propagation of bamboos from offsets is well known and practised in village groves. The development of planting material from branch cuttings is a two-stage operation. The first is the striking of roots and the other, the development of a rhizome. Getting vigorous rooted stock is not enough because this does not always develop rhizomes ; for this the biological condition of the buds is very important. In bamboos, successful planting material must have all the characters of growing clumps, the most important of which is the production of new culms. Though offsets are a good propagating material, these are not suitable for large scale plantations due to handling difficulties, long branch cuttings with swollen basal nodes and 2-3 branch nodes physiologically similar and can be made branch 18-20 inch are morphologically and to function like the offset in suitable conditions. Such cuttings develop into good planting material in 6-30 months, depending on the biological condition of the cutting and the period of the year when the cuttings were taken. The superiority of the branch cutting over the offset is in the fact that it is easy to raise, economic to produce, and convenient to transport. At the moment the percentage of success is low, and further research in the factors governing the production of planting material from branch cuttings is necessary.
