| Summary: | As a contribution to the study of the melliferous flora of Serbia, nectar
production in two species of the genus Galanthus L. (G. nivalis L., and G.
elwesii Hook.) was investigated. The intensity of nectar secretion was
determined directly, using the microcapillary method. The study included
determination of the total daily nectar amount per flower, and an analysis of
nectar secretion dynamics during the day and during the flower ontogeny. The
results show that the total daily amount of nectar per flower is low, and
flowers of both species exude nectar only once during the day and during the
flower ontogeny. However, despite the low nectar production, Galanthus
species represent a first valuable source of nectar and pollen to pollinators
in the early spring period, when only a small number of species are in the
flowering phenophase. |
