title: [Quantitative characters of male generative structures cells of wheat, rye and wheat-rye hybrids during microsporogenesis].
abstract: The optical density indices of nucleoli and cytoplasm of male generative cells during microsporogenesis have been estimated for wheat, rye and F1 of wheat-rye hybrids using RNA staining. The correlation between RNA con tent in the nucleolus and the cytoplasm of investigated cells has been estimated. The dynamics of correlation between the nucleolus volume and RNA content in the nucleolus/ the cytoplasm has been shown for wheat and hybrids cells during microsporogenesis. The essential differences depending on genotype for quantitative karyometrical and cytochemical character expression have been determined for parental forms, as well as dependence of expression of these characters in the cells of FI wheat-rye hybrids on wheat maternal form.
