Tennessee coneflower [Echinacea tennesseensis (Beadle) Small] was regenerated from flower stalks, leaf sections from flowering plants, and hypocotyls and cotyledons from seedlings. Murashige and Skoog medium (MS) supplemented with naphthaleneacetic acid (NAA) at 0.54 μM and thidiazuron (TDZ) at 22.7 μM yielded the most shoots per leaf explant. NAA and 6-benzylaminopurine concentrations for optimal shoot regeneration from leaf, flower stalk, cotyledon and hypocotyl explants in MS media were 0.54… CONTINUE READING
