Numbers, distribution and specific composition of diaspores in the soils of the plants associations Spergulo-Corynephoretum

The number, distribution (vertical and horizontal) and the specific composition of diaspores in dune sands were studied in two time periods of the growing season. It has been found that in spite of the high rate of diaspore production by the psammophytes, the number of diaspores in the soils of the community under study was fairly low, whereas their specific composition was much richer than that of the vegetation of the patch investigated. The diaspores, which were found to be primarily located in the surface layers of the soil, showed a clearly clumped type of distribution. They appeared to be accumulated first of all in local depressions and where there were aggregations of mature individuals. During the growing season the total number of diaspores and the quantitative relations between the diaspores of the particular species varied.
