“…According to López et al (1999) and Galloni et al (2007), the flowers of the studied species have created a pump mechanism of pollen presentation, which promotes several repeated visits to the same flower by insects. Pollen harvesting from the flowers of members of the tribe Genisteae (to which, among others, Laburnum belongs) has been confirmed by microscopic investigations of pollen loads and bee bread conducted in Poland and other European countries (Díaz-Losada et al 1998;Wróblewska, 2002;Sá-Otero et al 2007). The presence of the pollen of plants from the above-mentioned tribe has also been recorded in Polish honeys (Wróblewska, 2002;Stawiarz and Wróblewska, 2010).…”

a b s t r a c t a study on the flowering biology and pollen production of the common laburnum (laburnum anagyroides med.) was conducted under the conditions of lublin during the period 2004 -2006. the flowering of this species began in the second 10-day period of may and lasted for 2.5 -4 weeks. the flowers of common laburnum are borne in showy golden-yellow pendulous racemes. they develop successively, starting from the base and moving to the tip of an inflorescence. during the growing season, one shrub produces 800 to 3200 racemes, with 14 to 35 flowers in a single raceme. on average, the flowering duration for a raceme was 12.8 days and 8.7 days for a single flower. throughout the study years, the shrubs proved to be most attractive in the third 10-day period of may when they reached full bloom. the average weight of pollen produced was 6.08 mg per 10 flowers of laburnum anagyroides, 14.02 mg per raceme, and 26.0 g per shrub. pollen grains reached average dimensions of 24.01 µm × 24.26 µm.
