Use of DNA analyzes for verifying and identifying the origin of Forest Reproductive Material

Popis výsledku v původním jazyce

The level of genetic diversity of trees is crucial for the adaptation of forests to climate change and for sustaining forest ecosystems. It is widely assumed that populations characterized by narrow genetic diversity could be more sensitive to environmental changes or disease, thereby leading to a decrease in productivity. Knowledge about the genetic structure of forest tree species populations is very important in order both to maintain the ecological stability of forests and for the optimization of timber production. To verify the polymorphism and diversity of forest tree populations microsatellite marker analyses have been used in the FGMRI laboratories. The genetic differentiation between autochthonous and introduced populations from the Czech part of the Giant Mts. and among autochthonous populations of the Tatra Mts. of Pinus mugo was analysed by nuclear microsatellite markers. SSR analyses were used for determination and for verifying the declared genetic origin of reproductive material of 3 forest species (Norway spruce, Scots pine and European beech) in terms of the Czech Republic, too. The developed procedures of genetic monitoring by SSR markers could be used in the amendment of forestry legislation and in state subsidy policy in the area of protection and reproduction of forest tree gene resources in the Czech Republic.
