Opis:
The vascular flora in the “Łąki w Komborni” Natura 2000 site comprises 219 species representing 44 families and 147 genera. Species from the families Asteraceae, Poaceae, Lamiaceae, Fabaceae, Rosaceae, Polygonaceae, Cyperaceae, Apiaceae, and Ranunculaceae were found to dominate. A geographical and historical analysis of species confirmed the clear dominance of apophytes (84%) over anthropophytes (16%) as well as perennials (69%) over short-lived (23%) species. The biological spectrum was dominated by hemicryptophytes (54%) and therophytes (19%), compared with other life forms. In terms of synecology, the flora was mainly represented by species from the classes Molinio-Arrhenatheretea, Stellarietea mediae, Artemisietea vulgaris and Phragmitetea. The “Łąki w Komborni” site is a habitat for 82 (37%) medicinal species and 155 (70%) forage species for bees. Noteworthy is the occurrence of protected species, e.g. Gladiolus imbricatus, Trollius europaeus, Centhaurium erythraea, Dactylorhiza majalis, Platanthera bifolia and Primula elatior.

Opis:
The paper contains a phytosociological description and evaluation of alluvial meadows of Cnidion dubii Bal.-Tul. 1966 at the Natura 2000 site “Łęgi Odrzańskie”, the middle Oder river valley, presented in relation to local water conditions and grassland management. Phytosociological data of the C. dubii alliance from Poland and the Czech Republic have also been presented.

Opis:
We investigated the flowering probability and flower production in relation to plant size in a terrestrial orchid, Dactylorhiza majalis at 10 meadow sites in central and southwestern Poland. These sites differed in altitude (low, high) and management (presence or absence of mowing). At all sites, concentrations of nutrients in the soil were also measured. The probability of flowering increased significantly with the size of the plant in all populations, indicating that individuals do not flower until they reach a threshold size. Populations at high altitudes and the unmown sites had significantly lower threshold sizes for reproduction and showed sharp increase in flowering probability with plant size, compared to other populations. The threshold sizes for reproduction tended to decrease at sites rich in N and Mg and poor in P and S. Flower production was also size-dependent in all populations. Considerable between-site differences were found in the slope and the intercept of the regression between plant size and flower production. Flower production at some sites, at high altitudes, increased more steeply with plant size than at other sites. However, no pattern in size-dependent flower production was found relative to the measured environmental variables. Most of the size-dependent components of flowering probability were related to each other but not with the size-dependent flower production.
