Abstract
The issue of occurrence and size of red heart and the possibilities of its limitation in beech assortments have been researched in worldwide measures for a long time. There are many ecological, phenological, geological factors which more or less influence its formation. The results of a long-term research of different silvicultural treatment confirmed that a big crown of crop trees creates conditions to achieve the target diameter with a low assumption of red heart formation and so rises the quality and price of produced assortments. The different shaping of tree crowns on two investigated compartments had a significant impact on the size of dehydrated zone and subsequently on the frequency of red heart. On the contrary, it did not have a significant impact on the size of red heart, even though red hearts in the both investigated forest stands were small. We also found the different qualitative structure of assortments in both types of investigated compartments.
