Shoot induction in cultivars ‘RSL NFR’ and ‘Winter Density’ under different nutritional and hormonal conditions but no 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. 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
