Cytokinin growth regulators, 6-benzylaminopurine (BAP), kinetin (KIN), and 2-isopentenyladenine (2-iP), induced in vitro shoot multiplication from shoot explants of Echinacea purpurea (Eastern purple coneflower). Murashige and Skoog (MS) medium supplemented with 17.76 M 6-benzylaminopurine and 0.269 M naphthalene acetic acid produced the greatest number of adventitious shoots, although all cytokinin treatments with or without naphthalene acetic acid were effective in inducing shoots. Subsequent rooting and growth of the induced shoots in a potting media in a greenhouse demonstrated the new plants developed normally.
