Mean number of metamers in the basal and median zones (when present), mean number of metamers per shoot and mean number of associated flowers and fruit per shoot depending on the genotype (cvs and VP clones) and year of shoot development.

Genotype and year effects were analyzed using a Kruskal-Wallis test. Comparisons among genotypes and years were performed with a Wilcoxon-Mann-Whitney test. Different letters in a same variable indicate significant difference (p < 0.05) among cvs and VP clones and between years. The distributions extracted for the two years jointly were compared among genotypes separately.
