Abstract

Mladi izdanci, poznatiji kao 'microgreens', konzumiraju se u fazi kotiledona i nepotpuno razvijenih prvih pravih listova. Sadrže veću količinu minerala i bioaktivnih spojeva, a manje nitrata od biljaka u kasnijoj fenološkoj fazi. Cilj istraživanja bio je utvrditi utjecaj tri supstrata (komercijalni supstrat za uzgoj presadnica, mješavina komercijalnog supstrata i perlita, juta) na prinos i mineralni sastav mladih izdanaka brokule, cikle, poriluka, graška i suncokreta. Prosječno najveći prinos mladih izdanaka utvrđen je pri uzgoju na supstratu (1128 g/m2), a najmanji u uzgoju na juti (673 g/m2). Primjena mješavine supstrata i perlita rezultirala je najvećom prosječnom količinom N (7,02 % N/ST), sirovih proteina (43,85 % SP/ST) i K (394,41 mg K/100 g st) u mladim izdancima cikle. Najveća prosječna količina suhe tvari (8,04 % ST), fosfora (77,96 mg P/100 g st), kalcija (65,15 mg Ca/100 g st) i magnezija (40,57 mg Mg/100 g st) mladih izdanaka utvrđena je pri uzgoju na juti.

Abstract (english)

Young shoots, known as 'microgreens', are consumed in the cotyledon stage and the incompletely developed first true leaves. They contain more minerals and bioactive compounds and less nitrates than plants in the later phenological phase. The aim of the study is to determine the effect of three substrates (commercial seedlings substrate, a mixture of commercial substrate and perlite, jute) on the yield and mineral composition of microgreens of broccoli, beetroot, leek, pea, and sunflowers. On average, the highest yield was found in cultivation on the substrate (1128 g/m2) and the lowest in cultivation on the jute (673 g/m2). Use of substrate and perlite resulted in the highest average amount of N (7.02 % N/DW), crude proteins (43.85 % CP/DW) and the highest amount of K (394.41 mg K/100 g fw) in beetroot microgreens. Jute-grown shoots had the highest average amount of dry matter (8.04 %), P (77.96 mg/100 g fw), Ca (65.15 mg/100 g fw) and Mg (40.57 mg/100 g fw).
