Abstract

Dendrocalamus hamiltonii Nees and ex Munro, a versatile Bamboo of H.P.shows limitation in mass propagation through vegetative method using culm cuttings due to low ischolar_maining. Application of auxins (IBA, NAA) and Phenols (Gallic acid, Resorcinol and Vanallic acid) in various doses and duration caused dose specific stimulation in sprouting, ischolar_maining, rhizome formation and survival of its one year old culm cuttings planted in March.

Abstract

Single node cuttings from node one to ten of 6-8-month-old culms planted horizontally in March, ischolar_mained at the nodes. The bud of a cutting produced a dominant routed shoot and/or a cluster of precocious branchlets. Later some of the buds on the precocious branchlets also produced ischolar_mained shoots. Cuttings from the basal node of two and one-year-old culms, planted in July-August gave similar but subdued results. Some of the cuttings from the remaining culm lengths produced erratically reeoted shoots (i) by ischolar_maining of mature primary beanches (ii) from primary-branch buds with or without air-layering and (iii) from buds of precocious-branchlet stumps. The ischolar_mained shoots produced from their basal buds juvenile culms, each with typical neck and rhizome.
