Abstract

This master's thesis investigates the impact of plant growth-promoting fungi (Aspergillus clavatus and Mortierella elongata) on the yield components (height, diameter, mass) and content of bioactive compounds (phenols, flavonoids, non-flavonoids, total chlorophyll, chlorophyll a, chlorophyll b, carotenoids, ascorbic acid and antioxidant capacity) in lettuce (Lactuca sativa L.). The research was conducted through an open-field experiment, applying different subcultures of these PGP fungi to lettuce plants. Statistical analysis using the ANOVA method and Tukey's post-hoc test confirmed significant differences of bioactive compounds in inoculated treatments in comparision to uninocultaed (control). Higher values indicate that used PGP fungi, significantly enhance lettuce nutritional quality and contribute to the lettuce resilience, contributing to sustainable agricultural practices.

Abstract (croatian)

Ovaj diplomski rad istražuje utjecaj gljiva koje potiču rast biljaka (Aspergillus clavatus i Mortierella elongata) na komponentne prinosa (visina, promjer i masa) i sadržaj bioaktivnih spojeva (fenoli, flavonoidi, neflavonoidi, ukupni klorofil, klorofil a, klorofil b, karotenoidi, askorbinska kiselina i antioksidativni kapacitet) u salati (Lactuca sativa L.). Istraživanje je provedeno pokusom na otvorenom, primjenom različitih potkultura ovih PGP gljiva na biljke salate. Statistička analiza metodom ANOVA i Tukeyjevim post-hoc testom potvrdila je značajne razlike bioaktivnih spojeva u inokuliranim tretmanima u usporedbi s neionkuliranim
(kontrola). Više vrijednosti pokazuju da korištene PGP gljive značajno poboljšavaju nutritivnu kvalitetu salate i doprinose otpornosti salate, doprinoseći održivoj poljoprivrednoj praksi.
