Influence of growth regulators on the regeneration rate from leaf and stem explants. a Regeneration rate from leaf and stem explants after sixty days of cultivation. b Elongation rate of shoots produced from leaf explants on two different media. c Average root number and d rooting rate produced from six different media supplemented with different concentrations of a carbon source. Lowercase letters on the x-axis indicate the hormone and sucrose concentrations described in Table 3. 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
