| [genetic differentiation of pedunculate oak quercus robur l. in the european part of russia based on rapd markers]. | using randomly amplified polymorphic dna markers (rapd), genetic variation and differentiation in four populations of pedunculate oak quercus robur l. were examined. the populations occupy a large part of the quercus robur range in the european russia (voronezh and novgorod oblasts; republics of mordovia and bashkortostan). with each of six random primers (a02, a09, a17, b01, b08, b11), 96 dna samples were analyzed by pcr. in all, 48 putative polymorphic rapd loci were detected. we failed to rev ... | 2002 | 11898612 |
| [cytogenetic characteristics of seed progeny of trees under condition of antropogenic contamination in voronezh town]. | it has been shown that in seed progeny of quercus robur l., pinus sylvestris l. and betula pendula roth. some cytogenetical characteristics vary under conditions of contamination. such changes may be common or specific type. thus, the frequency of pathological mitosis increases under such conditions in all the investigated species of trees. inhibition of mitosis was found in the progeny of the pine, and variability in the number of nucleoli was detected in the pine and oak. however, in some case ... | 2000 | 10752126 |
