EFFECT OF EARTHWORM COELOMIC FLUID ON GROWTH OF PHYTOPATHOGENIC FUNGI FUSARIUM OXYSPORUM

Uloga gujavica i mikroorganizama u funkcioniranju ekosustava tla je dobro poznata, kao i postojanje povezanosti i interakcija između gujavica i gljivica u tlu. Međutim, do sada nije istražen utjecaj celomske tekućine i celomocita, imunoloških stanica gujavica, na rast gljivica u tlu. Naime, prilikom negativnog podražaja gujavice u okoliš mogu ispustiti sluz i celomsku tekućinu s celomocitima koja potencijalno može značajno utjecati na rast gljivica. Stoga je glavni cilj ovog rada bio istražiti učinak celomske tekućine gujavica na rast fitopatogenih gljivica. Ekstrakti celomske tekućine dviju različitih vrsta gujavica korišteni su kako bi se utvrdilo njihovo djelovanje na rast fitopatogene gljivice Fusarium oxysporum, iznimno važne vrste u poljoprivrednoj proizvodnji.The role of earthworms and microorganisms in the soil ecosystem functioning is well known, as well as existence of interactions between earthworms and fungi in the soil. However, the impact of coelomic fluid and coelomocytes, immune cells of earthworms, on the growth of the fungi has not been investigated so far. Namely, in case of negative stimuli earthworms can discard mucus and coelomic fluid containing coelomocytes which can potentially have a significant impact on the growth of fungi. Therefore, the main aim of this thesis was to investigate the effects of earthworm coelomic fluid on the growth of phytopathogenic fungi. Coelomic fluid extracts of two different earthworm species was used to determine the effects on the growth of phytopathogenic fungi Fusarium oxysporum, important in agricultural production
