abstract:
Effects of girdling with and without removal of a bark ring in «Ascolana tenera» olive-trees, whose charac
teristic is the variable yield, are reported in this study.
Girdling with and without removal of a bark ring, carried out before anthesis, increased the percentage of
setting of 40% the first one and of 70% the second one. The yield levels (resulted definitely low in control) resulted superior to 100% and 300%.
At the same time leaf diagnostic showed (between May and October) a decrease of leaf mineral composi
tion in leaves from girdled trees regarding N, Ca, Mg, P, Mg rates: in any case girdling with removal of a
bark ring showed more intense effects.
Considerable yield increases showed no bad influence on fruit morphology and quality.
