The effects of plant growth regulators were examined in order to optimize the callus induction, regeneration, and proliferation of lisianthus (Eustoma grandiflorum). In vitro leaves provided the explants for callus induction. Explants were cultured on Murashige and Skoog (MS) medium with different concentrations of indole-3-acetic acid (IAA), 1-naphthaleneacetic acid (NAA), and 2,4-dichlorophen...
