bee pasture - Opis:
- The flowering, nectar production and sugar content were examined in 2012–2013 seasons for three Campanula species (C. persicifolia L., C. glomerata L., C. trachelium L.). The flowers of all studied Campanula spp. are distinctly protandrous; most of them opened between 10.00 and 14.00; only the flowers of C. glomerata continued the opening process until 16.00 (GMT + 2 h). The flower life-span differed between species and was the longest for C. persicifolia – ca. 5.5 days and lasted 3.0–3.5 days in C. glomerata and C. trachelium. The duration of the male phase was 2–3 fold shorter (C. persicifolia and C. glomerata) than the female phase or was equal (C. trachelium). Irrespective of the year of study and the species, the female-biased nectar production pattern was evidenced. The amount of nectar accumulated at the female phase reached 70–87% of the maximum nectar produced by a flower. The total sugar yield (0.4– 12.2 g/10 m2) established for the studied species is low compared to other herbaceous meadow species. However, due to diverse insect visitors groups, the Campanula flowers can be recommended to support pollinators in home gardens or on idle lands.
