2,4-D (9.0 μM) and BA (8.8 μM) were found to be the suitable combination for friable callus induction; this was demonstrated in terms of a high induction percentage. Although there were media with higher callus induction, friable callus was induced on mentioned concentrations; this variation in callus induction/differentiation on different concentrations of growth regulators depends on the morphogenetic response which varies according to spatial and temporal cell distributions, and on physiological and developmental stages
