Large-scale vs. small-scale factors affecting flowering patterns in Senecio macrophyllus M.BIEB., a long-lived perennial

摘要

The aim of the study was to establish which of environmental factors affect flowering patterns in a long-lived herbaceous plant Senecio macrophyllus . The study was conducted in the population of Bia?a Góra (White Mountain) near Tomaszów Lubelski in the years 1989-2004. The results allow to conclude that in the reproductive patterns of the analysed population small-scale environmental factors (soil moisture and trophism, light intensity) are more important than large-scale climatic factors (temperature, precipitation), which to a comparable extent affect the plants in the whole population area.
