Abstract
Istraživanje fizikalno-kemijskih svojstava plodova jagode (Fragaria x ananassa) neutralne dužine dana sorte ‘Capri’ provedeno je 2018. godine. U istraživanju su korišteni plodovi jagode uzgojeni u ljetnom periodu na otvorenom na lokaciji Botinec, Zagreb, Republika Hrvatska.
Predmet istraživanja je kakvoća plodova jagoda s biljaka čiji je korijen tretiran prije sadnje mikrobiološkim preparatima uz dodatak hidrogela u tlo. Prije sadnje korijen sadnice jagoda sorte ‘Capri’ tretiran je mikoriznim preparatom Symbivit (Glomus spp.), kombinacijom Symbivita uz dodatak Plantasorba (hidrogel) u tlo, samo uz dodatak Plantasorba u tlo, te kombinacija Umico (huminski ekstrakt) i Radiscudo (Bacillus spp. i Glomus spp.).
Analizirana su sljedeća svojstva kakvoće jagode: masa ploda, visina i širina ploda, tvrdoća ploda, udio topljive suhe tvari u plodu, udio ukupnih kiselina u plodu te boja ploda. Za boju ploda analizirane su vrijednosti CIE L*, a*, b*, C* i H*.
Na temelju analize najveća masa ploda je zabilježena kod ne tretiranih (kontrolnih) biljaka (7,09 g). Omjer topljive suhe tvari i ukupnih kiselina bio je najveći kod tretmana mikorize (Symbivit) kombiniranog s hidrogelom (Plantasorb) koji iznosi 20,63. Najveći udio crvene boje je zabilježen kod kontrolnih (netretiranih) biljaka.The research of the physicochemical properties in the strawberry (Fragaria x ananassa) fruits with neutral day length, the 'Capri' variety, was conducted in 2018. The strawberries were grown in the field, in the summer season at the location Botinec, Zagreb, Croatia. The subject of the study was the properties of strawberry fruits of plants whose root was treated with microbiological preparations before the planting, with the addition of hydrogels to the soil. Before the planting, the root of the strawberry seedlings of the 'Capri' variety was treated in a few different ways: with mycorrhizal based product named Symbivit (Glomus spp.), with Symbivita in addition to Plantasorba (hydrogel) to the soil, with only the addition of Plantasorba to the soil and finally with combination of Umico (huminic extract) and Radiscudo (Bacillus spp. and Glomus spp.). The following strawberry fruits quality properties were analyzed: mass, height and width, hardness, content of the dry matter, total soluble solids, total acidity and fruit color. For the color of the fruit, the values of CIE L* and a*, b*, C* and H* were analyzed. Based on the analysis, the highest value of fruit mass was recorded in non-treated (control) plants (7.09 g). The highest ratio of soluble solids and total acids was recorded in the treatment with mycorrhizal based product (Symbivit) combined with a hydrogel (Plantasorb) of 20.63. The highest share of red color was observed in control plants (untreated plants)
