Abstract:Leta 2024 smo v nasadu jablan v Sadjarskem centru Maribor v Gačniku izvedli raziskavo, v kateri smo preučevali vpliv giberelinske kisline (GA4₊₇) in proheksadion-Ca (Pro-Ca) na zavezanost plodičev, količino pridelka, povratno cvetenje ter zrelostne in kakovostne parametre jabolk pri sorti 'Topaz'. Poskus je obsegal štiri obravnavanja (kontrola, GA4₊₇ x 1, GA4₊₇ x 3 in GA4₊₇ + Pro-Ca). Iz pridobljenih rezultatov je razvidno, da aplikacija GA4₊₇ samostojno ali v kombinaciji s Pro-Ca ni imela pomembnega vpliva na zavezanost plodičev, količino pridelka, povprečno maso plodov in povratno cvetenje. Prav tako aplikacija omenjenih pripravkov ni pomembno vplivala na vsebnost topne suhe snovi, trdoto mesa plodov, skupne titracijske kisline, škrobni indeks in Streifov indeks zrelosti. Nakazal se je le blagi trend zaviranja zorenja plodov pri uporabi Pro-Ca.

Title:Gibberellins ga4?7 and prohexadione-calcium influence on fruit set in the apple (malus domestica borkh.) cultivar ‘topaz’
Abstract:In 2024, a field trial was conducted in an apple orchard at the Fruit Growing Centre Maribor in Gačnik, in order to study the effects of gibberellic acid (GA₄₊₇) and prohexadione-calcium (Pro-Ca) on fruit set, yield, return bloom, as well as maturity and quality parameters of the 'Topaz' cultivar apples. The experiment included four treatments (control, GA₄₊₇ × 1, GA₄₊₇ × 3, and GA₄₊₇ + Pro-Ca). The results showed, that the application of GA₄₊₇ alone or in combination with Pro-Ca had no significant effect on fruit set, total yield, average fruit weight, or return bloom. Similarly, the treatments did not influence the soluble solids content, flesh firmness, titratable acidity, starch index, or the Streif maturity index. Only a slight trend towards delayed fruit ripening was observed with the use of Pro-Ca.
Keywords:apple tree, thinning, gibberellins, return bloom, yield
