Abstract

Mladi izdanci su slični klicama, ali za razliku od njih rastu nekoliko dana dulje. Zbog visokog sadržaja vrijednih nutritivnih tvari spadaju u funkcionalnu hranu zbog čega predstavljaju vrijedan kulinarski sastojak. Istraživanje mladih izdanaka tartarske, mađarske te varaždinske heljde je provedeno u vegetacijskim komorama Agronomskog fakulteta Sveučilišta u Zagrebu s ciljem utvrđivanja učinka genotipa te različitog spektra LED svjetlosti na sadržaj mikro (Fe, Zn, Mn, Cu) i makroelemenata (N, P, K, Ca, Mg), klorofila a i b te karotenoida. Rezultati su pokazali da postoje statistički značajne razlike u sadržaju dušika (N), fosfora (P) i magnezija (Mg) između genotipova unutar istog LED osvjetljenja kao i unutar istog genotipa tretiranog između različitih LED osvjetljenja dok su za sadržaj kalcija (Ca) utvrđene značajne razlike samo između genotipova pod istim LED svjetlom. Za sadržaj kalija (K) nisu utvrđene značajne razlike niti između genotipova unutar istog tipa LED osvjetljenja niti između različitih LED osvjetljenja unutar istog genotipa. Za sadržaj mikroelemenata te klorofila a i b utvrđene su značajne razlike između genotipova unutar istog LED osvjetljenja te između različitih LED osvjetljenja unutar istog genotipa. Sadržaj karotenoida se značajno razlikovao samo između genotipova tretiranih istim LED svjetlom.

Abstract (english)

Microgreens are similar to sprouts, but unlike them they grow a few days longer. Because of high content of valuable nutrients, they belong to functional foods, which is why they represent a valuable culinary ingredient. The research including microgreens of Tartar, Hungarian and Varazdin buckwheat was conducted in the growth chambers at the Faculty of Agriculture, University of Zagreb with the aim of determining the effect of genotype and different spectrum of LED light on the content of micro (Fe, Zn, Mn, Cu) and macroelements (N, P, K, Ca, Mg), chlorophyll a and b as well as carotenoids. The results showed that there were statistically significant differences in the content of nitrogen (N), phosphorus (P) and magnesium (Mg) among genotypes within the same LED lighting and among different LED lightings i within the same genotype, while for the calcium (Ca) content significant differences were found only among different genotypes under the same LED light. For potassium (K) content no significant differences were found either between or within genotypes. For the content of microelements and chlorophyll a and b significant differences were found among genotypes within the same LED light and among different LED lightings within the same genotype. For the content of carotenoids significant differences were observed only among genotypes treated with the same LED light.
