Biodiversity monitoring of forest stands of deciduous species based on molecular marking
Journal Title: Лісівництво і агролісомеліорація - Year 2016, Vol 129, Issue
Abstract
In the article the results of the level of genetic variation assessment, subdivision and differentiation of forest stands of European aspen (Populus tremula L.), silver birch (Betula pendula Roth.) and English oak (Quercus robur L.) on the territory of Belarus, its eastern border regions and the Republic of Tatarstan are presented. The investigation was conducted by using isozyme, RAPD- and SSR-markers. It was shown that the analyzed tree species are characterized by wide range of indicators of genetic diversity. According to isozyme analysis at the species level the share of polymorphic loci (P99) ranges from 0.385 to 0.769, the average number of alleles (A) ranges from 1.923 to 3.231, observed heterozygosity (Ho) ranges from 0.114 to 0.227, expected heterozygosity (He) ranges from 0.115 to 0.237. The lowest values of P99 and A are revealed in forest stands of European aspen. The lowest values of Ho and He are revealed for silver birch stands. English oak stands are characterized by the highest level of genetic variation on all indicators. Based on the DNA analysis the lowest values of the genetic diversity are revealed in aspen stands. Analyzed tree species are characterized by low levels of subdivision and differentiation.
