Elimination and molecular identification of endophytic bacterial contaminants during in vitro propagation of Bambusa balcooa.

Bambusa balcooa is an economically important, multipurpose bamboo species, decidedly used in construction industry. Availability of natural bamboo is depleting very rapidly due to accelerated deforestation and its unrestrained use. The large number and timely supply of saplings are the need of the hour for the restoration of bamboo stands.

Influence of plant growth regulators on callus mediated regeneration and secondary metabolites synthesis in Withania somnifera (L.) Dunal.

Withania somnifera (L.) Dunal, is an important medicinal plant being the source of extremely important compounds like withanolides and withaferin. Influence of different plant growth regulators (PGRs) were evaluated for induction of callus, callus mediated regeneration and production of secondary metabolites in them.

A two step method for accelerated mass propagation of Dendrocalamus asper and their evaluation in field.

An accelerated protocol for large-scale propagation of Dendrocalamus asper, an edible bamboo, has been described. Seven axillary shoots were induced in vitro from each excised tender node (15-20 mm in length) containing single axillary bud when nodal segments were inoculated in semisolid Murashige and Skoog (MS) medium fortified with 5 mg/l 6-benzylaminopurine (BAP). Maximum multiple shoot formation (14) was observed when in vitro generated axillary shoots were transferred to liquid MS medium containing 5 mg/l BAP and 40 mg/l adenine sulphate.
