Results of the phytochemical analyses of fruits of nine genotypes of Greek Sambucus nigra that were established in the pilot cultivation trial under conventional fertilization, organic fertilization, and control (no fertilization). The measured phytochemical attributes were total flavonoids (TF, mg catechin equivalents 100 g−1) and ascorbic acid content (AA, mg ascorbic acid 100 g−1), whereas the measured physicochemical attributes were pH, total soluble solids (TSS, °Brix), and total acidity (TA, g citric acid 100 g−1). The results are given as means ± SD (n = 5).

Means that do not share the same letter are significantly different based on respective Tukey’s HSD post hoc tests (p < 0.05). Lowercase letters within each column reflect comparisons between genotypes under the same fertilization treatment. Capital letters within each line reflect comparisons between fertilization treatments in the same genotype and attribute. The cases where SD was 0.0 were not included in the post hoc test, as they stemmed from the assessment of one replicate plant that produced fruits. In columns or lines where no respective lettering is given, no significant differences were observed.
