Analýza plodnosti dubu letního (Quercus robur L.) na LZ Židlochovice (lokalita Soutok)

The main concern of this work was observation of acorn yield depending on the tree position in forest (solitaire, forest edge tree, integrated tree and tree in the close nature forest). Further, quality of acorns was observed by ČSN standard and seed ability to survive natural regeneration was also observed. The research was conducted in the years 2011-2013, using deployed seed traps under selected trees and their regular monitoring. The results show that most fructifying are solitary trees and least integrated ones. Acorn quality was low and its ability to overwintering was minimal. Main reason of the poor quality was infestation by insects and fungi
