Abstract
Jablana (Malus × domestica Borkh.) je sadna vrsta, ki cveti konec aprila in v začetku maja, vendar se ta čas zaradi toplih pomladi pomika vse bolj proti začetku aprila. Če nastopi zmrzal, smo lahko ob ves pridelek, zato se priporoča uporaba sredstva za krepitev rastlin. Leta 2019 smo v Hortikulturnem centru Biotehniške fakultete, Univerze v Ljubljani, na jablani sorte 'Opal' analizirali vpliv pripravka Phylgreen (ekstrakta iz morskih alg Ascophyllum nodosum) in Novagib (giberelini) na pridelek ter kakovost plodov jablane. Na izbranih plodovih smo merili prirast. Ob tehnološki zrelosti smo vse plodove obrali, jih umestili v ustrezni kakovostni razred, prešteli in stehtali. V laboratoriju smo izbranim plodovom izmerili višino, širino in maso. Iz vsakega obravnavanja smo izbrali po 20 plodov, na katerih smo izvedli zrelostne teste (masa, barva, trdota, topna suha snov, škrobni test) in s sistemom tekočinske kromatografije visoke ločljivosti (HPLC) določili vsebnost posameznih in skupnih sladkorjev in organskih kislin ter spektrofotometrično vsebnost skupnih fenolov. Po skladiščenju smo ponovno analizirali plodove in rezultate med sabo primerjali.

Title:The impact of the seaweed extract and gibberellins on the crop and the fruit quality of the apple cultivar 'Opal'(Malus x domestica Borkh.)
Abstract:
Apple (Malus × domestica Borkh.) is a fruit species that blooms in late April and in the beginning of May, but this time, due to the warm springs, is moving more and more towards the beginning of April. Later, however, frost occurs, due to which it can take the whole crop. Therefore, we have the ability to use plant strengthening agents. In 2019, at the Horticultural Centre of the Biotechnical Faculty, University of Ljubljana, on the apple variety 'Opal', we analysed the effect of Phylgreen (seaweed extract Ascophyllum nodosum) and Novagib (gibberellins) on yield and quality of apple fruit. We measured growth of selected fruit. At technological maturity, we harvested all the fruit, placed them in quality classes, counted and weighed them. In the laboratory, we measured the height, width and weight of the selected fruits. From each treatment we selected 20 fruit on which we performed maturity tests (weight, colour, flesh firmness, soluble solids, starch test) and by High-performance liquid chromatography (HPLC) the content of individual and total sugars and organic acids, and the spectrophotometric content of total phenols. After storage, the analyses were repeated and the results compared.
