Summary: | This paper presents the results of an investigation related to mycological
populations of rapeseed samples produced in the Institute of Field and
Vegetable Crops in Novi Sad (location: Rimski Sancevi, Novi Sad), with a
special emphasis on the potentially toxigenic mycopopulations. Mycological
investigations were performed on the samples that were treated with 4%
solution of Na-hypochlorite, and on the ones that were not submitted to this
treatment. Isolation and determination of total mould count was carried out
using Dichloran Glycerol Agar (DG18). The identification of isolated moulds
was done according to modern keys for fungal determination. From 20 untreated
tested samples, 17 were contaminated with moulds (10.0 to 4.7x102 cfu/g).
When the samples were treated with 4% solution of Na-hypochlorite, moulds
were isolated only form 4 samples, and the total mould count ranged from 10.0
to 60.0 cfu/g. In the isolated mycopopulations, xerophilic moulds dominated,
especially those from the genera Aspergillus, Eurotium and Penicillium. In
the isolated mycopopulations, high degree of isolated species belonged to
toxigenic species from the genera Alternaria, Aspergillus, Fusarium, Eurotium
and Penicillium. |
