ANTIFUNGALNA AKTIVNOST ETERIČNIH ULJA I NJIHOVIH GLAVNIH KOMPONENTI NA RAST MICELIJA Colletotrichum coccodes. (Croatian)

The effect of five essential oils (anise, peppermint, basil, rosemary and true lavander) and their two most common components on the mycelial growth in Colletotrichum coccodes, economically important phytopathogic fungi and compared with fungicides have been investigated in the study. Tests were conducted in vitro conditions in eight volumes on a PDA substrate in four replicates. The increase in mycelium was measured on the eighth and fifteenth day after the mycelium inoculation. It was found out that some essential oils and components applied at a given volume have a significant antifungal effect, in some examples comparable to fungicides. Anise and peppermint essential oils as well as the anethole component had the best activity and the lowest IC 50 . Fifteen days after the inoculation of the mycelium, the essential oils had a significantly better antifungal activity compared to their second most represented component. [ABSTRACT FROM AUTHOR]

U radu je ispitivan utjecaj pet eteričnih ulja (anisa, paprene metvice, bosiljka, ružmarina i lavande prave) i njihovih dviju najzastupljenijih komponenti na porast micelija Colletotrichum coccodes, ekonomski značajne fitopatogene gljive i uspoređen s fungicidima. Ispitivanja su provedena u uvjetima in vitro u osam volumena na PDA podlozi u četiri ponavljanja. Porast micelija mjeren je osmi i petnaesti dan nakon nacjepljivanja micelija. Utvrđeno je da neka eterična ulja i komponente, primijenjeni u određenome volumenu, imaju signifikantan antifugalni učinak, u pojedinim primjerima usporediv s fungicidima. Najbolje djelovanje i najniži IC 50 imala su eterična ulja anisa i paprene metvice te komponenta anetol. Petnaesti dan nakon inokulacije micelija eterična ulja imala su značajno bolje antifungalno djelovanje od svoje druge komponente po zastupljenosti. [ABSTRACT FROM AUTHOR]
