Sucrose is a necessary external carbon substrate for in vitro microtuber induction and development. In this study, we determined the correlation between sucrose and microtuber formation in potato by investigating the role and significance of sucrose in the medium and the origin of explants, as well as the potential function of sucrose in microtuber formation in vitro. Sucrose strongly influence...

Optimum concentrations of nitrogen and potassium on in vitro microtuberization of Agria, a popular variety of Potato, Solanum tuberosum L., were evaluated. The concentrations of 0, 0.5, 1, 1.5, and 2 folds of standard concentrations of NH4NO3 (1650 mgl) and KNO3 (1900 mgl) were used in Murashige and Skoog (MS) medium, and their effects were studied on cell number, cell sizes, and number of amid...
