In vitro regeneration of bamboos, the "Green Gold": An overview

Abstract

regeneration of bamboos. PGRs like 6-benzylaminopurine (BAP), indole-3-acetic acid (IAA), indole-3-butyric acid (IBA), kinetin (Kn), 1-naphthaleneacetic acid (NAA), 2,4 dichlorophenoxyacetic acid (2,4-D) were mostly preferred over others for bamboo micropropagation, while 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) and gibberellic acid (GA3) were also used in some cases. Direct in vitro shooting was preferred in regeneration of bamboos over somatic embryogenesis through callus culture. In vitro rhizogenesis was well achieved in presence of phytohormones but was not solely depended on them. Further, regenerated plantlets were successfully established in the field with high rate of survival. In the present review we endeavor to give a consolidated account of in vitro regeneration of bamboos starting from the pioneer work initiated in 1968.
