Effects of carbon sources and auxins on in vitro propagation of banana

The effects of carbon sources (sucrose, glucose, fructose and mannitol) and auxins [indolebutyric acid (IBA) and alpha-naphthaleneacetic acid (NAA)] on in vitro propagation of banana (Musa spp. AAA) were studied. Over all carbon sources tested, sucrose induced highest frequency of shoot proliferation. Optimal shoot proliferation rates were achieved on the Murashige and Skoog (MS) medium supplemented with sucrose and glucose combination (1:1) at the concentration of 30 g dm(-3). Similarly, higher frequency of root induction was obtained at IBA and NAA combination (1:1; concentration of 2 mg dm(-3)) than at other concentrations of IBA or NAA alone or their combinations.
