Pollen Grain Size Polymorphism in Late Tulip (Tulipa gesneriana L., 1753) Cenopopulations within the Territory of “Ivanovo Field” Natural Boundary

One of the large populations of the late tulip (Tulipa gesneriana L., 1753) grows in Fedorovsky district of the Saratov region on the territory of the regional “Ivanovo field” natural boundary where it is presented by three cenopopulations. The work is aimed at studying of mature pollen morphology of the given cenopopulation plants characterised by various variants of flower parts coloration. We analysed the dimension and other morphological features of the pollen fixed in 2012 when rich diversity of floral envelope coloration was registrated in the research area.
