Abstract: | Five sessile oak Quercus petraea (Matt.) Liebl.] stands from the Czech Republic were studied to learn about the impact of different types of forest management
regimes on the genetic differences among tree populations and on population structures. One population had not been markedly
affected by human activity, two populations represented unplanted stands that were extensively managed for a long period of
time using the coppice system, and two populations were planted stands. Approximately 100 trees from each stand were mapped
and subsequently genotyped using 10 nuclear microsatellite loci. We determined the spatial genetic structure of each population
and the genetic differentiation among the populations. We found that: (i) the populations were genetically differentiated,
but the differences between the unplanted and planted stands were not markedly significant; (ii) the genetic differentiation
among the populations depended on the geographical distribution of the populations; (iii) within unplanted stands, a strong
spatial genetic structure was seen; and (iv) within planted stands, no spatial genetic structure was observed. Our findings
implies that the analysis of spatial genetic structure of the sessile oak forest stand can help reveal and determine its origin. |
