Abstract
The morphometric parameters of the panicle of the initial breeding material of three species of the genus Miscanthus were determined. Panicle length of Miscanthus sacchariflorus and Miscanthus sinensis is 18-20 cm, width is 8-11 cm, and for Miscanthus х giganteus it is 20-23 cm and 14-16 cm, respectively. Miscanthus is a monoecious plant; its flower bears both the pistil and the stamen. The color of anthers varies from yellow to pinkish-yellow. Anther tissues are composed of elongated cells 70-100 µm long. The pistil has an ovary with two styles, which bear long feathery stigmas. The stigma length is 2.0-2.8 mm. The stigma varies in color from white to bright pink. The shape of stigma feathery is moderately branched. The number of small branches is 10-15. The location is alternate. The length of the pistil feathers is 160-300 microns; the width is 20-30 microns. The pollen of various Miscanthus species differs in qualitative and quantitative characteristics as size, homo- or heterogeneity. Thus, the pollen of Miscanthus sacchariflorus and Miscanthus sinensis is characterized by a rounded shape, evenness and uniformity, 43-48 µm in diameter, while the pollen of Miscanthus х giganteus is more heterogeneous in size, its diameter is 23-45 µm. The pollen has one rounded ornamented pore with a diameter of 2.7-4.0 microns.
