POLLEN AND BEE POLLEN FEATURES OF SWEET CHESTNUT (CASTANEA SATIVA MILL.)
Abstract
The aim of this work was to study general morphological characteristics of pollen grains and bee pollen of sweet chestnut (Castanea sativa Mill.). The studies were carried on pollen extracted from genotypes, which are cultivated in M.M. Gryshko National Botanical Garden (Kyiv). Bee pollen was collected by selves. The polar axis and equatorial diameter of pollen grains values were varied from 12.58 to 24.39 μm and 7.10 μm and 13.92 μm, respectively. Value of the form of pollen grains was ranged from 1.09 to 2.64 μm. For the bee pollen the height in the range 2.01–3.91 mm and width in the range 1.42–3.19 mm were determined.
