Shoot induction in cultivars ‘RSL NFR’ and ‘Winter Density’ under increasing concentrations of AC. The number of explants which produced at least one shoot 8 weeks after excision were quantified for all treatment groups and expressed as a percentage of the total explant number. A minimum of N = 45 explants were evaluated per treatment group, and a minimum of N = 120 explants were evaluated for treatment groups M17, M18 and M19. Data were pooled and are presented as mean ± SD. Significant differences between the control group and each treatment group were analyzed by a one-way ANOVA followed by a Dunnett test (**p ≤ 0.01, ****p ≤ 0.0001). Data does not reflect size, growth speed or overall quality of the shoots. Media M20 and M21 not shown since no shoots were produced for either cultivar. Media M17 not shown for cultivar ‘WD’ since it was tested only on cultivar ‘RSL NFR’
