Sestavení lokálních letokruhových chronologií na základě dendrochronologického datování roubených hospodářských staveb z jihovýchodní Moravy

The subject of the thesis is to determine the age of individual farm buildings by means of dendrochronological analysis and compilation of local tree-ring chronologies of the given tree species. The work describes a detailed procedure for dendrochronological dating from sampling and preparation of samples through measurements to their dating. The work also deals with the use of individual trees in structures. The oldest building is a barn from the village of Vrbětice made of beech, whose design elements were dated to 1766/1767. On the other hand, the youngest building can be labeled as a fruit dryer from the village of Pradlisko. Taken oak samples from the construction managed to date to 1944/1945. The most represented tree species in the surveyed farm buildings were beech and oak. Other trees are represented in very small numbers to determine their importance in the structure. The oak elements were used in the construction mainly for foundation sills and the beech elements for the construction of the walls. With regard to the number of samples of individual trees, two local ring-shaped chronologies were created. The beech chronology consists of ring-shaped curves of 29 samples taken from historical structures and 22 ring-shaped curves from live trees, with a non-interconnected section of approximately 93 years between the two parts. Combining these two parts, the chronology would be able to cover more than 300 years (1690–2013). Oak local chronology is made up of ring-shaped curves of 30 samples from the surveyed objects and covers the period from 1700 to 1900. Since there is no beech chronology for the Czech Republic, it is a great contribution to making the basic beech chronology for this region, where beech is the most used wood in buildings. The work contributes to the building of beech chronology
