SEED RAIN AND SEED PERSISTENCE OF CALAMAGROSTIS EPIGEJOS (L.) ROTH IN EXTREME ECOTOXICOLOGICAL CONDITIONS AT AN ABANDONED ORE-WASHERY SEDIMENTATION BASIN

Popis výsledku v původním jazyce

Clonal plants are very often among the first species to establish during primary succession. They may rapidly capture available space due to efficient vegetative propagation, but the question arises whether they may also rely on seed bank or seed rain during expansion and recovery after a possible disturbance. This question becomes increasingly important in extreme conditions of industrial deposit investigated in this study. We explored the two aforementioned seed sources in a clonal grass Calamagrostisepigejos within an ecotoxicologically stressed environment - abandoned tailings containment (former sedimentation basin) - from manganese-ore mining. Density of seeds found in seed rain was 617 seeds m-2, and in soil seed bank 220 seeds m-2, based on anautumn survey. Soil seed pool was almost depleted until the following spring as only 13 seeds m-2 were present. This pattern contrasted with the capacity of C. epigejos to build a persistent soil seed bank as shown by a burial experiment
