Abstract

Tijekom 2018. godine u laboratoriju Agronomskog fakulteta u Zagrebu obavljena je analiza kvalitete plodova jagode stalnorađajuće sorte 'Murano' i jednorodne sorte 'Joly' uzgojenih na tri različite lokacije u Zagrebačkoj županiji. Dva tipa uzgoja koja su uspoređivana su bila hidroponski sustav u supstratu i sustav uzgoja gdje je korijen bio u tlu. Ispitivani fizikalni parametri bili su masa (g), tvrdoća (kg/cm2) i boja ploda, a kemijski topljiva suha tvar (oBrix) i ukupne kiseline (g/L). Iako postavljena hipoteza daje prednost hidroponskom sustavu uzgoja, najbolje odnose parametara kvalitete ploda su pokazali plodovi stalnorađajuće sorte neutralnog dana 'Murano' iz sustava uzgoja u tlu.
U obje berbe, sorta 'Murano' iz sustava uzgoja u tlu je imala najmanju masu ploda (19,48 g) i najtvrđe plodove (0,57 kg/cm2) te je ovime dokazana negativna korelacija parametara mase i tvrdoće ploda jagode opisana ranije u literaturi. Isti plodovi su pokazali najviše vrijednosti omjera topljive suhe tvari i ukupnih kiselina (1,78) u drugoj berbi dok su u prvoj berbi jedino signifikantno niže vrijednosti spomenutog parametra zabilježene kod plodova sorte 'Murano' iz hidroponskog sustava uzgoja (0,93).

Abstract (english)

In 2018., in the laboratory of Faculty of Agricultural sciences in Zagreb, fruit quality of day-neutral strawberry 'Murano' and short-day strawberry 'Joly' from three different locations in Zagreb County was examined. Two types of cultivation systems were compared and those were hydroponics and conventional soil-based cultivation system. Examined physical parameters were weight (g), firmness (kg/cm2) and colour of the fruit and chemical parameters were total soluble solids (oBrix) and total titratable acidity (g/L). Although the set hypothesis puts a preference on the hydroponic cultivation system, the best correlation of fruit quality parameters was observed in fruits of day-neutral strawberry ‘Murano’ from soil-based cultivation system.
Fruit of day-neutral strawberry ‘Murano’ from soil-based cultivation system had the lowest weight value (19,48 g) and highest fruit firmness (0,57 kg/cm2) which proves the negative correlation of these two parameters mentioned in the literature. Same fruits had the highest value of soluble solids and total acidity ratio (1,78) in the second harvest, while in the first harvest only fruits of the strawberry ‘Murano’ grown in the hydroponics system had significantly lower values (0,93) of the mentioned parameter.
