This volume contains the following four papers:
Structure, dynamics and population biology of Dentaria glandulosa (Cruciferae). I. Life history in relation to habitats variability:
The paper is the first part of a monograph dealing with population biology of Dentaria glandulosa W. et K. The characteristic site conditions and genet and module life cycles of Dentaria glandulosa are described. The results obtained enable both a quantitative and qualitative modelling of developmental stages of individuals as well as description of long-term dynamics of above-and underground parts.
Structure, dynamics and population biology of Dentaria glandulosa (Cruciferae). II. Size, age and spatial structure:
Size, age and spatial structure of Dentaria glandulosa W. et K. in three locations (Ojcow, Ponice, Grzeskowki) are analyzed with special attention paid to both the short-living aboveground parts and persistent underground ones. The morphology and height structure of the aboveground parts were analyzed. The density of individuals, vertical and horizontal distribution of underground organs, their morphology, frequency distribution of length and thickness of rhizomes were also assessed. Developmental stages of individuals and ageistructure of annual segment increments in particular populations were considered.
Structure, dynamics and population biology of Dentaria glandulosa (Cruciferae). III. Effectiveness of generative and vegetative reproduction:
In the present paper, issues on flowering, fruiting and effectiveness of generative and vegetative reproduction of Dentaria glandulosa W. et K. are discussed, based on multiyear observations. It was also attempted to compare potential and real reproduction characteristics.
Structure, dynamics and population biology of Dentaria glandulosa (Cruciferae). IV. Biomass, primary productivity and multi-year dynamics of underground organs:
The paper describes biomass dynamics of above- and underground organs of Dentaria glandulosa W. et K., as well as net primary productivity of all herb layer species in the stand of Dentaria glandulosae-Fagetum in yearly and seasonal cycles. The length and mass of particular segments of annual growth were correlated, based on multi-year dynamics of fresh and dry mass of under- and aboveground organs. Long term studies on developmental rhythmics enabled the yearly cycles and activities of under-and aboveground organs for mountain and non-mountain populations to be assessed.
