Efficient low cost seesap (CSUP) technique for micropropagation of newly introduced sweetener plant, Stevia rebaudiana Bertoni

Stevia rebaudiana is a non-caloric sweetening herb, which has a high potential for commercialization. During this study low cost media sterilization, seesap (CSUP) technique which applies sodium hypochlorite was used as an alternative to autoclaving. In vitro cultures were established using nodal segments collected from stevia mother plants. These in vitro shoots were cultured on Murashige & Skoog (MS) medium...
