Micropropagation of Bambusa vulgaris var. striata

Bambusa vulgaris var. striata is a widely cultivated bamboo species in rural Madhya Pradesh for its versatile uses. The vegetative propagation becomes the only viable alternative for this species because B. vulgaris does not set seed after sparse flowering, which makes seedling progenies unavailable. A low-cost propagation trial was conducted to explore the clonal propagation techniques for the species with two types of small branch cuttings, nodal leafy cuttings and tip cuttings. The cuttings, after treating with 1, 2 per cent and 0.1 per cent, solutions of, bavastin and Hgcl₂ were kept in non-mist propagator to let them to ischolar_main for assessing the ischolar_maining ability. The cuttings were ischolar_mained in three weeks and were allowed to grow in the polybags for 6 months under nursery condition. The study reveals that both types of branch cuttings are able to develop ischolar_mains, shoots, to survive and to form rhizome under the nursery condition. Rooting ability of the cuttings was significantly enhanced by the application of ischolar_maining hormone — IAA. The length of the longest ischolar_main varied significantly neither with the cutting types nor the concentrations of IAA solution.
