Trochinskaya, T. G. | Blankovskaya, T. F. | Totskii, V. N.
The optical density indexes of nucleoli and cytoplasm of male generative cells during microsporogenesis have been determined for wheat, rye, and F₁ of wheat-rye hybrids using RNA staining. The positive correlation between the RNA content in nucleoli and cytoplasm of the cells of all plants has been found. The dynamics of correlation links between the nucleolus volume and RNA content in the nucleolus/cytoplasm of the wheat and wheat-rye hybrids in microsporogenesis and early gametogenesis have been shown. The essential species and sort differences based on quantitative cytochemical and karyometrical characteristics in parental forms and the dependence of their appearance in interspecies F₁ hybrids on wheat's maternal form have been identified.
