Variabilita šířky letokruhu a konvenční hustoty dřeva vybraných dřevin po výšce kmene na Drahanské vrchovině

Becha, Lubomír January 2016 (has links)
The aim of the thesis is the determination of the spring and summer wood percentage, annual ring´s width and conventional density of the chosen woody plants and its dependence on the trunk´s level. For these purposes were researched 9 different trees. It was taken 10 wooden segments from the each chosen level of the trunk. It was chosen program WinDendro and it was made dendrochronological analyses and measurement of the spring and summer wood. It was used Olson´s mathematics figure for the conventional density calculation. In this calculation it is always used maximum level of the wood volume. The outcome is the number which is almost realistic figure of the conventional density change and structure change of the annuals´ rings. These outcomes are measured in the transection and cross section.

Dendrokronologisk undersökning av Quercus sp. och Pinus sylvestris i nationalparken Blå Jungfrun / Dendrochronological examination of Quercus sp. and Pinus sylvestris in the National Park Blue Maiden

Haraldsson, Jesper January 2019 (has links)
This study involved a dendrochronological examination of oak (Qeurcus.sp) and Scots pine (Pinus.sylvestris) in the nationalpark Blå Jungfrun, by measuring annual ringwidth data from tree-cores from the island, data from the national forest inventory and climatedata from the Swedish Meteorological and Hydrological Institute (SMHI). Using the analysis program Windendro an annual ringwidth analysis was performed. Trends that occured were that pine respondend more to precipitation than temperature and that oak respondend more to temperature. Ringwidth were higher for Scots pine than oak and for both species lower than on the mainland.
