Abstract

V nalogi smo ugotavljali vpliv pripravka NovaGib na količino pridelka in kakovost plodov (Malus domestica Borkh.) sorte 'Bonita'. Poskus smo izvajali v Hortikulturnem centru Biotehniške fakultete Orehovlje in je obsegal tri obravnavanja: kontrolo, obravnavanje G1 (1x NovaGib 0,7 l/ha) in obravnavanje G2 (2x NovaGib 0,35 l/ha). Zaradi aprilske pozebe smo vsa drevesa, tudi kontrolna, tretirali s pripravkom NovaGib s konc. 0,15 l/ha in 0,5 l/ha. Ugotovili smo, da pripravek NovaGib ni imel značilnega vpliva na pridelek in delež plodov 1. kakovostnega razreda. Pripravek ni imel značilnega vpliva na obarvanost, trdoto, vsebnost topne suhe snovi, vsebnost škroba in vsebnost posameznih sladkorjev, organskih kislin ter skupnih fenolov. Ugotovili smo, da je pripravek pozitivno vplival na velikost plodov, saj se je linearno s številom nanosov povečevala višina, premer in masa plodov. Do značilne razlike je prišlo v višini plodov med kontrolo (58,11 mm) in G2 (60,19 mm), v premeru plodov med kontrolo (66,53 mm) in G2 (68,21 mm) in v masi plodov med kontrolo (129,50 g) in G2 (141,95 g). Do spremembe oblike ni prišlo, plodovi so se enakomerno povečali v premeru in v višino. Značilne razlike smo zabeležili pri parametrih osnovne in krovne barve. Zaradi vpliva zunanjih dejavnikov, predvsem spomladanske pozebe ter suše in mladosti dreves priporočamo, da se poskus ponovi.

Secondary title: ǂThe ǂimpact of gibberelin solutions on the fruit shape of apple (Malus domestica Borkh.) 'Bonita' variety
Secondary abstract: The purpose of the master thesis was to determine the impact of NovaGib on the yield and fruit quality of apple cultivar 'Bonita.' The study was conducted at the Horticultural Center of the Biotechnical Faculty in Orehovlje. The study included 3 treatments: control, treatment G1 (1x NovaGib 0.7 l/ha), and treatment G2 (2x NovaGib 0.35 l/ha). Due to the April frost, all trees, including the control one, were treated with NovaGib with conc. 0.15 l/ha and 0.5 l/ha. NovaGib did not significantly affect the yield and share of the 1st quality class fruits. There was no statistical impact on colour, hardness, soluble solids, starch test, and content of individual sugars, organic acids, and total phenols contents. NovaGib had a positive impact on fruit size, as the fruit's height, diameter, and weight increased linearly with the number of NovaGib applications. There were significant differences between control and G2 in fruit height (control: 58.11 mm, G2: 60.19 mm), fruit diameter (control: 66.53 mm, G2: 68.21 mm), and fruit weight (control: 129.50 g, G2: 141.95 g). There was no change in shape; the fruits increased evenly in diameter and height. Significantly differences were observed in the background colour and overcolour parameters. We recommend repeating the experiment due to external factors, especially spring frost and drought, and the youth of trees.
