Effetti dell'anulazione del tronco nell'olivo (Ascolana tenera) / Spano, Donatella Emma Ignazia; Virdis, Filippo Bruno Ardito; Dettori, Sandro. - In: STUDI SASSARESI. SEZIONE 3: ANNALI DELLA FACOLTÀ DI AGRARIA DELL'UNIVERSITÀ DI SASSARI. - ISSN 0562-2662. - 31:(1984), pp. 153-162.
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.
