This callus was also yellowish green in colour with granular appearance (Fin.2). Again the callogenic response was excellent roughly being 80% (Table 1). still further in another set of experiments the concentration of NAA was kept the same (0.1 mg. ) while that of BAP increased to 1.0 mg. level. This combination was not very effective as only a slight callus was formed on the nodes after 5-6 weeks. Although this callus was brownish white and soft in the beginning, later on it turned brown ang died very rapidly.The percentage of explants which responded to callus formation was also low.
