Strojna rez krošnje žlahtne jablane (Malus domestica Borkh.) sorte 'Gala' kot ukrep za povečanje cvetnega nastavka

Petrovič, Nejc (avtor), Hudina, Metka (mentor)

Strojno rez jablan mnogi vidijo kot nepogrešljivo v pridelavi jabolk. Vendar preden se vpelje v uporabo kot standard, je treba opraviti številne študije. V Hortikulturnem centru Biotehniške fakultete smo v letih 2018 in 2019 opravili poskus na žlahtni jablani (Malus domestica Borkh.). Preučevali smo odzivnost sorte 'Gala' na strojno rez. Raziskovali smo, kako poletna strojna rez vpliva na cvetni nastavek, nadaljnjo rast in kakovost plodov. V poskus smo vključili dve obravnavanji: strojno rez (obe strani vrste) in kontrolo. Poletno strojno rez smo izvedli v letu 2018 po obiranju pridelka s strojem FAMA CKP 250. Rezultati raziskave so pokazali, da poletna strojna rez ni značilno povečala števila socvetij, je pa povečala število plodov na drevo. Količina pridelka je bila pri strojni rezi skoraj dvakrat večja kot pri kontroli tako I. kot II. kakovostnega razreda. Strojna rez ni vplivala na kakovost plodov, razen na vsebnost topne suhe snovi. Glede na ugotovitve raziskave se poletno strojno rez priporoča, vendar mora biti kombinirana z redčenjem. Za preostale sorte pa zaradi možnosti drugačnega odziva na strojno rez priporočamo dodatne raziskave.

Izvleček

Mechanical pruning of apple trees many see essential in apple production. However, before it is put into use as a standard, a number of tests have to be carried out. In the years 2018 and 2019, we conducted an experiment on apple trees (Malus domestica Borkh.) at the Horticultural Center of the Biotechnical Faculty. We studied the responsiveness of the cultivar 'Gala' to a mechanical pruning. We researched how summer mechanical pruning effect on return bloom, further growth and fruit quality. The study consists of two treatments: a mechanical pruning (both sides of the row) and control. In the summer pruning was made in the year 2018 after harvest with machine FAMA CKP 250. The results of the study showed that the summer mechanical pruning did not significantly increase the number of flower clusters, but increased the number of fruits per tree. Mechanical pruning increased quantity of the yield for almost twice compared to the control, I. and II. class. Mechanical pruning did not affect the fruit quality except for the soluble solids content. According to the findings of the study, we recommended summer mechanical pruning, but it must be combine with thinning. However, for other cultivars we recommended additional research, because of the possible different response of cultivar on mechanical pruning.
