Abstract

A method is presented for the in vitro propagation of Datura insignis Barb. Rodr. Nodal explants were cultured on Murashige and Skoog medium supplemented either with BA alone or in combination with 2,4-D or IAA. Shoot multiplication and elongation were obtained in various growth regulator concentrations. Best results were obtained in a medium with 1.0 mgl-1 of BA. Individual shoots were excised and transfered to growth regulator-free medium for rooting. Additional multiplication was obtained by single-node culture using explants from these in vitro rooted shoots. Rooted plantlets were successfully grown in soil.
