Plant Introduction| Резюме: | Genetic peculiarities of trees with maximum and minimum productivity of full-grained or empty seeds were studied in four Pinus pallasiana D. Don stands of the Krivoy Rog region. It is shown that heterozygosity levels are not significantly different in four combined groups of trees from all stands, those groups being characterized by a considerable differences in seed productivity. Heterozygosity levels of these groups were also not significanty different from average heterozygosity of every stand, on the basis of electrophoretic analysis of variation of isozymes of 9 enzyme systems. Notable differences in heterozygosity levels were revealed in plant groups with alternative seed productivity at some of 18 polymorphic allozyme loci. |
