Morfologická charakteristika peľových zŕn niektorých medonosných druhov rastlín

Abstract

The aim of the monography is presentation of pollen grain characteristics from selected group of plant species. The evaluated group consists of plants that are traditionally cultivated such asHelianthus annuus L., Prunus avium (L.) L.; rarely used such as Castanea sativa Mill., Aronia melanocarpa (Michx.) Elliott; less known species Diospyros kaki L.; invasive species Solidago gigantea Aiton; ornamental species Mahonia aquifolium (Pursh) Nutt., naturally occurring plant speciesTaraxacum sect. Ruderalia, Lamium purpureum L., Cichorium intybus L, Crataegus monogyna Jacq.; as well as species used for bees’ pasture in Slovakia such as Phacelia tanacetifolia Benth., from which bees are gathering nectar and pollen for their feeding. Flowers were gathered from selected plants at the start of full bloom. In laboratory conditions, the pollen was released from stamen and subsequently dried and placed on stubs to be prepared for observation and photographed on scanning electron microscope. Pollen grains were classified based on internationally recognized methodology...
