Kivonat:

A native plant species [Cleistogenes serotina (L.) Keng] earlier known from the mountain regions of Hungary recently has invaded some sandy habitats of the Great Hungarian Plain. Among criteria of the successful invasion the reproductive capacity was also studied based on the comparisons of different mountain and sandy populations. The formation of cleistogamous seeds is much more intensive than chasmogamous seeds in every habitats. The quantity of cleistogamous seeds depending on the number of shoots and leaves per plant is the greatest in the sandy habitat. The reproductive output is the most effective in the populations of sandy and sandstone habitats. But there are no spatial constrains in the distribution of Cleistogenes serotina in the sandy habitat.
