Popis: | Results of karyological study of Siberian spruce from natural population and some districts of Krasnoyarsk are presented. Except typical chromosome number (2n = 24) most trees from city have one or two B-chromosomes (2n = 24 + 1B; 2n = 24 + 2B). In natural population all trees have only 2n = 24. System of B-chromosomes is of importance for population and species adaptation and possibly plays role for adaptation of P. obovata in condition of anthropogenic contamination. |
