La recolonisation des champs abandonnés par l’espèce forestière Anemone nemorosa L.: II - Rythme saisonnier, reproduction et potentialité générative des population de forêt, de broussailles et de prairie.

The recolonization of abandoned fields by means of the forestal species Anemone nemorosa L.: II - Seasonality, reproduction and generative potentiality of forest, shrubs and grassland populations. - Anemone nemorosa as pioneer of the forest recreation on oldfields was investigated in permanent study areas on the Bialowieza Primeval Forest and Bialowieza clearing (Poland). Studies on seasonality, seeds production and generative reproduction potentiality were carried out. Considerable differences were found between three population of Anemone nemorosa (in Tilio-Carpinetum forest, shrubs and grassland) showing, in spite of reaction to the exceptional climate, a bigger role of generative reproduction as normal characteristic for the individuals in pioneer conditions.
