Abstract

Heljda (Fagopyrum esculentum) je pseudožitarica poznata kao dobar izvor hranjivih tvari koja se može konzumirati u obliku klijanaca i mladih izdanaka s izraženim nutritivnim vrijednostima. Evaluacija mladih izdanaka i klijanaca heljde pod LED i FLUO osvjetljenjem provedena je u laboratoriju te vegetacijskim komorama Agronomskog fakulteta Sveučilišta u Zagrebu. Cilj istraživanja bio je utvrditi sadržaj suhe tvari, sirovih proteina te mikro- i makroelemenata kod klijanaca i mladih izdanaka heljde te sadržaj klorofila i karotenoida kod mladih izdanaka heljde uzgojenih pod FLUO i LED osvjetljenjem. Mladi izdanci uzgajani pod FLUO osvjetljenjem imali su veće vrijednosti P, K, Ca, Mg u odnosu na LED, dok je N imao veće vrijednosti u mladim izdancima heljde uzgajanim pod LED osvjetljenjem. FLUO osvjetljenje pozitivno je utjecalo na koncentraciju Zn i Cu, a LED osvjetljenje na koncentraciju Fe i Mn. Klijanci su pokazali veće koncentracije svih mikro- i makroelemenata u odnosu na mlade izdanke. Sadržaj klorofila a bio je veći pod LED osvjetljenjem, dok je klorofil b bio veći pod FLUO osvjetljenjem. Sadržaj karotenoida bio je podjednak.

Abstract (english)

Buckwheat (Fagopyrum esculentum) is a pseudocereal known as a good source of nutrients that can be consumed in the form of sprouts and microgreens with notable nutritional values. Evaluation of buckwheat microgreens and sprouts grown under the LED and the FLUO lighting was carried out in the laboratory and vegetation chambers of the Faculty of Agriculture, University of Zagreb. The aim of this study was to determine the content of dry matter, crude proteins and micro- and macroelements in buckwheat sprouts and microgreens, as well as the content of chlorophyll and carotenoids in buckwheat microgreens grown under the LED and the FLUO lighting. Microgreens grown under the FLUO had a larger amount of P, K, Ca, Mg compared to LED. Yet, buckwheat microgreens grown under the LED had higher N concentration. FLUO ligthing positively affected the concentration of Zn and Cu, whereas the LED had a positive impact on the concentration of Fe and Mn. Opposed to microgreens, sprouts had higher concentration of all micro- and macroelements. The chlorophyll a content was larger under the LED, while the content of chlorophyll b was larger under the FLUO. The carotenoid content remained equal.
