SUMMARY
Results of this research indicate that seed of common ragweed is a favorable substrate for
development of many different microorganisms, among which fungi take important place.
Therefore, saprophytic and parasitic mycobiota of common ragweed seed from natural
populations are studied in this publication. Common ragweed seeds were collected from
five localities: Budisava, Novi Sad-Detelinara, Kać, Bački Maglić and Kisač. Within methods
that were used (ISTA-International Rules for Seed Testing), we determined presence of fungi
from the following genera: Fusarium, Sordaria, Alternaria, Epicoccum, Chaetomium,
Penicillium, Cladosporiumand Aspergillus. The most commonly isolated fungi was Chaetomium
spp.Seed contamination rate greatly varied depending on locality between 19,1
and 50%. Mixed infections with fungi from different genera were common. High common
ragweed seed contamination endangers purity of essential oil which is used in pharmaceutical
and cosmetic industry due to possible mycotoxin synthesis. Additionally, as Ambrosia
artemisifolia is widely distributed weed in our country, against which it is necessary to regularly
apply chemical and mechanical control measures, results of this research may also
indicate the possibility to use biological agents in control of common ragweed.
Key words: mycobiota, seed, Ambrosia artemisiifolia
