Fresh weight.
Alternate bearing index (ABI) from the 3rd to the 14th year after planting, which was calculated according to Pearce and Doberšek-Urbanc (1967).
Bienniality index (B) from the 3rd to the 14th year after planting, which was calculated according to Monselise and Goldschmidt (1982).
Within each row, values with the same letter are not significantly different according to Friedman test followed by Dunn's comparison adjusted by Bonferroni at P = 0.05; or according to one-way repeated measures followed by Tukey's test at P = 0.05. No letter was added to any value when no significantly different pairwise comparisons were detected.
