Streszczenie w języku polskim

The study is concerned with the group properties of five populations of Spergula vernalis Willd. in relation to abiotic and biotic habitat conditions. Measurements of density included frequenry, numbers and biomass, taking into account the participation of the different plant organs in biomass. The distribution of individuals in space was estimated and the results supplemented by examination of the degree of their aggregation. The natality of the populations was described on the basis of several factors: flowering and fruiting biology, pollen and seed germination capacity, fruit and seed production, weight and caloric value of seeds. Curves of survivorship were given for the populations, plotted on the basis of the number of individuals dying in several stages of ontogenesis and the net growth index of the populations .
