20.500.12556/DKUM-74382 Protiglivni učinek izvlečkov listov bele murve Anti-Fungal effects of white mulberry leaf extracts Murva je že od nekdaj prepoznavna po farmakoloških učinkih in je priznana v kitajski tradicionalni medicini kot protivnetno, antibakterijsko sredstvo in za zdravljenje hiperglikemije. Namen diplomske naloge je bil proučiti zaviralni učinek izvlečkov listov bele murve na rast glive Alternaria sp. V preliminarnem poskusu smo vrednotili učinek vodnega in etanolnega izvlečka v 5 %, 10 % in 20 % koncentraciji. Koncentracijskega učinka nismo potrdili, se pa je zaviralni učinek bolj izražal pri uporabi vodnega izvlečka. V drugem sklopu poskusa smo uporabili 37,5 % koncentracijo vodnih izvlečkov sedmih različnih genotipov bele murve, tako svilogojsko uveljavljenih sort 'Morettiana' in 'Kokusou', kot tudi lokalnih genotipov bele murve iz različnih fitogeografskih območij Slovenije. Zaviralni učinek smo dokazali pri treh lokalnih genotipih, ki so v osemdnevnem opazovalnem obdobju odražali skupno povprečno prirast 1,660; 2,860 in 3,790 cm2 napram ostalim genotipom z osemdnevnim skupnim povprečnim prirastom v območju 11,250 do 19,840 cm2 in kontroli s 17,498 cm2 prirasti. Sorti 'Morettiana' in 'Kokusou' sta izkazovali slab zaviralni učinek na rast glive. The mulberry has long been recognized for its pharmacological effects and is renowned in Chinese traditional medicines as an anti-inflammatory, antibacterial agent and for treatment of hyperglycemia. The purpose of the diploma thesis was to research the inhibitory effects of white mulberry leafs extract on the growth of the Alternaria fungus. In the preliminary experiment we evaluated the effects of water and ethanol extracts with concentrations of 5 %, 10 % and 20 %. The concentration effect was not confirmed, whereas the inhibitory effects on fungal growth were better reflected when water extracts were used. In the second part of the experiment, water extracts of seven different genotypes in the concentration of 37,5 % were used. The genotypes represented the sericultural varieties ‘Morettiana’ and ‘Kokusou’, as well as local white mulberry genotypes from different phytogeographic areas of Slovenia. The inhibitory effect was confirmed for three local genotypes by evaluating the average total eight-day period growth area, that was 1,660; 2,860 and 3,790 cm2, respectively. In contrast, other chosen genotypes represented a total average growth area between 11,250 and 19,840 cm2, whereas the fungal growth on control medium had an average of 17,498 cm2. The ‘Morettiana’ and ‘Kokusou’ varieties showed insufficient inhibitory effects on fungal growth.
