Cytogenetic characteristics of seed progeny of old-aged trees of Pinus pallasiana and Picea abies (Pinaceae)
Information on cytogenetic changes in the seed offspring of old-aged trees is insufficient and inconsistent. In our studies, 150–200-year old trees of Picea abies and Pinus pallasiana were used. We analyzed peculiarities of their karyotype, nucleus-forming region, and nucleolus in the cells of seedl...

| description | Information on cytogenetic changes in the seed offspring of old-aged trees is insufficient and inconsistent. In our studies, 150–200-year old trees of Picea abies and Pinus pallasiana were used. We analyzed peculiarities of their karyotype, nucleus-forming region, and nucleolus in the cells of seedlings of P. abies and P. pallasiana emerged from seeds in natural populations and plantations of introduced plants. As a result, age-dependent cytogenetic disorders were observed, such as the chromosome bridges, lag, premature segregation, and agglutination. Peculiarities with regard to number and structure of secondary chromosome constriction are demonstrated. The identified properties of the cell structure of seeds of old-aged trees of P. abies and P. pallasiana indicate that more resources are needed to maintain their protein synthesis at a normal level. The increased number of abnormalities indicates a significant impact of accumulated intracellular metabolites and cytopathological phenomena in mother plants on the quality of seed offspring. |
