Abstract

Endophytic fungi continuously demonstrate their promising candidature for“biotechnological machines” to be utilised in agriculture and medicine. Since paclitaxel,peramine and lolines, more than 20 natural products have been launched on theinternational market between 2001 and 2005 and approximately 140 are in differentdevelopment levels in all therapeutic areas. By far, studies on their potential use asseeds protectants against phytopathogenic fungi are scarce. Five crude extractsobtained from endophytic fungi, residing in different Artemisia species were tested for their bioprotection potential against Alternaria brassicicola on radish seeds. Biomass offive endophytic strains cultivated on rice was solvent extracted and their extracts wereused as treatment for the radish seeds. All extracts exhibited a high protection potentialtowards plantlets and no negative influence on their development was observed. Theextract 1053 revealed a low value of the necrosis index (1,83) in treated seeds after 30minutes of immersion compared to the control (6,67). Extract 1092 reduced the necrosisindex by 2,91 folds compared to the control. Effects of the treatment with extract 1051registered lower values for both 5 and 30 minutes incubation (1,92 and 3,15,respectively) compared to the control (6,93). Extract 1057 showed a value of 26 % of theone obtained in the control group of plantlets. Extract 1086 demonstrated a necrosisindex of 3,6, after 30 minutes of incubation compared to the value of 6,93 of the controlgroup.
