Effect of various SIMs on callus induction from leaf and stem explants. Calluses induced from leaf explants a and stem explants b after 4 weeks of cultivation. The values shown are the mean (± SE) of 20 explants. Different letters indicate significant differences among temperatures for each day as determined by Duncan’s multiple range test followed by one-way ANOVA at the p < 0.05 significance level. For the SIM number, see Table 1
