Abstract
Fitopatogene glive predstavljajo velik izziv in znatno oviro pri proizvodnji rastlinskih izdelkov na globalni ravni. Povzročajo lahko namreč bolezni tako pri gostiteljskih rastlinah kot pri organizmih, ki jih zaužijejo. Tako kvarijo kakovost in količino pridelka ter negativno vplivajo na zdravje ljudi. Posledično se poslužujemo številnih preventivnih ukrepov, ki preprečujejo njihovo širjenje, a imajo ti pogosto neželene učinke na človeka ali okolje. Dekontaminacija z nizkotlačno hladno plinsko plazmo (HPP) predstavlja okolju ter zdravju prijazno alternativo kemijski obdelavi semen. V tej nalogi smo se osredotočali na učinkovitost odstranjevanja glivnih vrst Aspergillus flavus in Fusarium fujikuroi. Preverjali smo njuno odpornost proti različnim načinom, moči ter trajanju izpostavitve HPP. Gliva F. fujikuroi se je izkazala kot nekoliko bolj odporna proti obdelavi s HPP kot A. flavus. Pri obeh smo dosegli večjo stopnjo dekontaminacije pri daljših obdelavah v neposrednem načinu izpostavitve HPP. Moč HPP v našem primeru ni imela jasnega vpliva na učinkovitost dekontaminacije, saj smo v primeru neposrednega gojenja zaznali razlike, pri posredni metodi gojenja (CFU) pa ne. Sklepamo, da je večja odpornost glive iz rodu Fusarium posledica razlike v morfologiji spor. Obdelave, ki so učinkoviteje odstranile glivne spore, so prav tako znižale kaljivost zrnja, kar omeji uporabnost te metode za dekontaminacijo materiala namenjenega za setev.

Title:Comparison of decontamination efficiency of selected fungal species from the surface of buckwheat grains upon treatment with glow and afterglow cold oxygen gas plasma treatment
Abstract:
Fungal phytopathogens pose a global-scale challenge to plant-based products. The disseases they cause on both, the host organism and its consumers, have a direct impact the quality of the product itself, as well as human health and safety. Consequently, the use of potent antimycotics to prevent their spread is common practice. However, the use of such substances is often associated with undesirable side effects. low-pressure cold gas plasma (LPCP) decontamination offers a more environmentally friendly and overall safer alternative to chemical disinfectants. In this work, we observed the effect of LPCP wattage, exposure type and duration on the fungi Aspegillus flavus and Fusarium fujikuroi. The latter was found to be marginally more resilient and was slightly less affected by all forms of exposure, which we suspected may be due to to be potentially caused by differences in spore morphology. Both fungi were more efficiently removed by longer and more direct exposures, while plasma power had no conclusive effects, as direct cultivation yielded observable results while indirect cultivation (CFU) did not. Additionally, the parameters that more efficiently removed fungal spores also negatively affected the ability of the treated plant to germinate, leading us to conclude that the treatment method is not suitable for seeds intended for sowing.
