Kentucky bluegrass is a facultative apomict which is propagated from seeds of variable genetic origins, ploidy levels and nuclear DNA contents. This study analyzes the variability of relative nuclear DNA content among cultivars and natural populations, and examines whether this variability is correlated with morphological traits. Relative nuclear DNA content (an indirect measure of chromosomal variability)...
Endoreduplication of nuclei is a common phenomenon in plants. Cells with multiplied DNA content are usually termed endopolyploid or polysomatic. The study was aimed at clarifying the chromosomal status of endoreduplicated nuclei. So far it has been generally assumed that endoreduplicated nuclei represent a form of polyploidy. We propose a distinction between true polyploid nuclei, possessing multiple...
The distribution of plastids at the time of microspore and pollen grain development in Gagea lutea (L.) Ker.-Gaw. was analyzed using electron microscopy. It was shown that plastids are not transmitted to the forming generative cell of this species during microspore division. At the vacuolate microspore stage, preceding division, the microspore nucleus takes an acentric position and the plastids gather...
