| Summary: | Studies on changes in the occurrence of Avena fatua L. and its varieties on arable land were carried out in 1990, 1994 and 1995. Strong expansion of the species was found. In 1990, 12 stations where A.fatua occurred with intensity above 1% were recorded, in 1994, 29 such stations were found, and 67 stations in 1995. Varieties A and F were most frequent, and variety E occurred in the lowest numbers. Dependence between the size of a population of a given variety and its geographical location were found. |
