vegetation - Opis:
- In the last few decades, changes of reproductive pattern of polar vascular plants have been observed, for the benefit of generative propagation. The reasons for this phenomenon are attributed to intensively following climate change, whose effects may be various. Warming causes the production of the greater number of generative structures, with higher quality. Our macroscopic observations conducted on specimens of polar vascular plants, cultivated in University of Warmia and Mazury greenhouse, indicate that the effect of temperature increase on flower development and seed formation is inconsistent. On the other hand enhanced levels of UV-B radiation can negatively affect seedlings. The complexity of the climate change causes tremendous difficulties in defining a clear and unquestioned way of modifications during the reproductive phase of the described plants.
