FIRST REPORT OF ACREMONIUM CHARTICOLA (LINDAU) W. GAMS ON RAPESEED SAMPLES IN STORAGE DURING 2012 IN SERBIA

Last years in Serbia rapeseed is being grown on much bigger areas than before. In our country it belongs to the category of crops whose time will come. The objective of this study was to investigate fungal infestation of different rapeseed genotypes (20) as it follows: Banacanka, Slavica, Branka, Ilia, Kata, Nena, NS-I-31, NS-I-32, NS-I-33, NS-I-101, NS-I-102, NS-I-126, NS-I-128, NS-I-129, NS-I-134, NS-I-136, NS-I-137, NS-I-138, Jasna and Zorica. Rapeseed genotypes were grown on the experimental field of the Institute of Field and Vegetable Crops, Rimski Sancevi, Novi Sad, Province of Vojvodina, Serbia. Samples were collected during the storage. Cultivation of rapeseed samples and isolation of fungi were done by use of two media: potato dextrose agar (PDA) and filter paper (FP). Incubation was carried out at 25 oC for 10 days. Isolated fungi were classified into five genera and nine species: Acremonium charticola (Lindau) W. Gams, Alternaria alternata (Fr.) Keissler, Aspergillus flavus Link, Aspergillus niger van Tieghem, Phoma glomerata (Corda) Wollenweber & Hochapfel, Phoma macrostoma Montagne, Penicillium chrysogenum Thom, Penicillium citrinum Thom and Penicillium rugulosum Thom. The first evaluation of mycopopulations was performed 7 days after setting of the experiment. The second evaluation was performed 5 days after the occurrence of fungi on seed and the third followed 10 days after it. The results were statistically analyzed by the program STATISTICA 12. It was found that the highest share in mycopopulations isolated on PDA and FP had Acremonium charticola and Aspergillus flavus. The last one is known as a producer of aflatoxins and some other toxic metabolites. Other species occurred at a significantly lower intensity. It is the first report of Acremonium charticola on rapeseed in Serbia.
