Pridelek jablane (Malus domestica Borkh.) sorte 'Zlati delišes' škropljene z giberelini in proheksadion-kalcijem po spomladanski pozebi 2020

Vovko, Maja (avtor), Hudina, Metka (mentor)

V diplomskem delu smo želeli ugotoviti, ali škropljenje s pripravkoma Novagib (giberelini) in Regalis Plus (prokehsadion-kalcij) po pozebi vpliva na večji in kakovostnejši pridelek jablane (Malus domestica Borkh.) sorte 'Zlati delišes'. Poskus smo izvedli leta 2020 v nasadu jablan v Šmarju pri Šentjerneju. V poskus smo vključili dve obravnavanji: kontrolo, kjer dreves nismo tretirali s pripravkoma Novagib in Regalis Plus, in obravnavanje, kjer smo drevesa po pozebi tretirali s pripravkoma Novagib in Regalis Plus. Drevesom smo izmerili parametre vegetativne rasti in generativnega razvoja. Izpostaviti moramo, da pa se je zmanjšal delež I. kakovostnega razreda, ki je bil pri kontrolnih drevesih večji, kot pri tretiranih drevesih. Koeficient rodnosti je bil večji pri kontrolnih drevesih. Tretiranje dreves s pripravkoma Novagib in Regalis Plus ni imelo vpliva na višino in širino ploda, vsebnost topne suhe snovi in titracijskih kislin, je pa vplivalo na večjo trdoto mesa in večjo vsebnost škroba, kar nakazuje, da so bili plodovi manj zreli v primerjavi s kontrolnimi plodovi.

• Naslov: Yield of apple (Malus domestica Borkh.) cultivar ´Golden Delicious´ sprayed with gibberellins and prohexadione-Calcium after the spring frost 2020

Izvleček

In the graduation thesis we wanted to find out whether spraying with Novagib (gibberellins) and Regalis Plus (prohexadione-calcium) after frost affects a bigger and high quality yield of apple (Malus domestica Borkh.) cultivar 'Golden Delicious'. The experiment was carried out in 2020 in an apple orchard in Šmarje near Šentjernej. Two treatments were included in the experiment: a control where the trees were not treated with Novagib and Regalis Plus, and a treatment where the trees were treated with Novagib and Regalis Plus after frost. The parameters of vegetative growth and generative development were measured in trees. It should be pointed out, however, that the percentage of I. quality class decreased, which was higher in control trees than in treated trees. The yield coefficient was higher in control trees. Treatment with Novagib and Regalis Plus had no effect on fruit height and width, soluble solids and titratable acid contents, but increased fruit firmness and starch content, indicating that the fruits were less mature compared to control fruits.
