In Vitro Propagation of \u3ci\u3ePennisetum purpureum\u3c/i\u3e Schum.

A protocol is described for rapid multiplication of elephantgrass (Pennisetum purpureum Schum.) through shoot tip culture. The plant growth medium consisted of basal medium of Murashige and Skoog (MS) and vitamins Wood Plant Medium (WPM). The medium was supplemented with 0.00; 4.44; 8.88; 13.32 and 17.76 μM of benzylaminopurine (BAP). The elephantgrass was micropropagated by axillary shoot proliferations. Maximum propagule proliferation occurred on Murashige and Skoog (MS) medium enriched with 4.4 μM benzylaminopurine (BAP), resulting an average of 4.0 shoots per explant from cultivar Mineiro and 2.19 from cultivar Pioneiro. The best height and root plantlets were obtained with medium without growth regulator after 28 days
