Abstract

Namen magistrskega dela je bil ugotoviti, ali pripravki Amalgerol Essence (alge), Delfan Plus (aminokisline) in Novagib (giberelini) vplivajo na pridelek jablane (Malus domestica Borkh.) sorte 'Idared' v času spomladanskih nizkih temperatur. Poskus je potekal v dveh nasadih jablane v Zagaju (Bistrica ob Sotli) leta 2021. V poskus smo vključili dve obravnavanji: kontrolo in obravnavanje, kjer smo uporabili pripravke, ki delujejo proti pozebi. Pri obravnavanju uporaba pripravkov proti pozebi smo drevesa škropili 1. in 5. aprila s pripravkom Amalgerol Essence (3 l/ha), 9. in 16. aprila s pripravkoma Amalgerol Essence (3 l/ha) in Delfan Plus (1,5 l/ha) in Novagib (0,5 l/ha) ter 23. aprila s pripravkoma Amalgerol Essence (3 l/ha) in Delfan Plus (1,5 l/ha). Drevesom, ki smo jih vključili v poskus, smo izmerili parametre vegetativne rasti in generativnega razvoja. Uporabljeni pripravki so vplivali na večje število plodov I. kakovostnega razreda in na velikost plodov, ki so bili večji in težji. Večje je bilo skupno število plodov na drevo, pridelek na drevo in koeficient rodnosti v primerjavi s kontrolnimi drevesi. Pripravki so vplivali tudi na obarvanost plodov. Posledično je bil večji pridelek na hektar ter večji delež pridelka I. kakovostnega razreda. Pripravki niso imeli vpliva na trdoto mesa, število pečk, topno suho snov in vsebnost titracijskih kislin.

Secondary title: Yield of apple (Malus domestica Borkh.) cultivar `Idared` sprayed with algea [!], amino acids and gibberellins after the spring frost 2021
Secondary abstract: The objective of the master's thesis was to determine whether the preparations Amalgerol Essence (algae), Delfan Plus (amino acids), and Novagib (gibberellins) affect the yield of the apple cultivar (Malus domestica Borkh.) 'Idared' at low temperatures in spring. The trial took place in two apple orchards in Zagaj (Bistrica ob Sotli) in 2021. The experiment included two treatments: a control treatment and a treatment in which we used preparations against frost. In the treatment with antifreeze preparations, the trees were sprayed with Amalgerol Essence (3 l/ha) on April 1 and 5, with Amalgerol Essence (3 l/ha), Delfan Plus (1.5 l/ha) and Novagib (0.5 l/ha) on April 9 and 16, and with Amalgerol Essence (3 l/ha) and Delfan Plus (1.5 l/ha) on April 23. The parameters of vegetative growth and generative development were measured for the trees included in the experiment. The preparations used had a positive effect on the number of fruits in the first quality class and on the size of the fruits, which became larger and heavier. The total number of fruits per tree, yield per tree and yield coefficient were higher compared to the control trees. The preparations also affected fruit coloration. The result was a higher yield per hectare and a higher percentage of yield in the first quality class. The preparations had no effect on fruit firmness, number of seeds, soluble solids content, and titratable acids content.
