Description
Summary:An efficient protocol has been developed for the root culture of (Cichorium intybus L. cv. Focus), the leaf and hypocotyl explants from 25 days old in vitro raised seedlings were cultured on half-strength Murashige and Skoog (MS) medium supplemented with different concentrations and combinations of Indole-3-acetic acid (IAA), Indole-3-butyric acid (IBA), α-Napthalenacetic acid (NAA). 0.5 mg/l NAA and 0.1 mg/l IBA induced highest percentage of rooting from matured leaf explants, under total dark condition. After three weeks well established roots were separated. Fresh root tissue, in amount of 0.5 was subcultured in half-strength MS liquid medium supplemented with 0.2 mg/l NAA and 0.5 mg/l IBA, under continuous agitation at 110 rpm and total dark condition. The biomass of root culture was increased to 5.820 g after 6 weeks of culture. The root culture was maintained up to the 8 weeks.
