Abstract

Due to the increasing human effect, more and more species are getting close to extinction. The disappearance of a species can lead to the extinction of other ones and degradation of the habitat as these biotopes are quite complex systems. Considering these factors and the increasing extinction rate the protection of the species came to the focus in the last few years. The knowledge of plant biology and reproduction seems to be essential for the effective protection work, what helps to predict the succession pattern and the regeneration ability. The regeneration of a plant community always base on the natural seed bank, and it can be described with the seed viability and germination ability. The aim of the research is the seed viability measurements of four species belong to the Fabaceae family (Astragalus cicer, Astragalus contortuplicatus, Astraglus glycyphyllos, Trifolium arvense). The main experiments were focused on the seed longevity and its dependence on the seed weight. The decreasing of hardseedness was also tested.
