Previous field research show, that late successional species correspond with soil development, especially with organomineral A horizon developing. Aim of my thesis was to compare plant growth on different types of soil from spoil heaps. They were taken from three chronosequencies of different age - nonrecultivated and soils recultivated with planting of alder (Alnus) and spruce (Picea). In my research were used 7 types of plants - Arrhenatherum elatius, Centaureae jacea, Festuca rubra, Lychnis flos-cuculi, Lotus corniculatus, Plantago major, Trifolium medium. Spontaneous sites support more species than reclaimed ones this difference increase with plot age without distinct difference between early and late succession species. Key words Succession, recultivation, germination alder (Alnus), spruce (Picea), Arrhenatherum, Centaureae, Festuca, Lychnis, Lotus, Plantago, Trifolium.
