Kvalitet sjemenskih sastojina bijelog bora (Pinus sylvestris L.) i crnog bora (Pinus nigra Arnold) u Federaciji Bosne i Hercegovine

Abstract

This research aims to determine the quality of Scots pine (Pinus sylvestris L.) and Austrian pine (Pinus nigra Arnold) seed stands in Federation of Bosnia and Herzegovina, and to recommend measures for the improvement of these stands for producing the highest quality reproduction material of researched species. For this research, 23 traits of trees in fourteen seed stands of Scots pine, and twelve stands of Austrian pine in the Federation of Bosnia and Herzegovina were analysed. Four traits were measured, and nineteen traits were assessed. The results showed the good condition of seed stands of investigated traits for the most of investigated stands. Some of the stands have shown very good quality, and individual selection should be made in them, while in other stands it is necessary to remove part of the trees. Considering the great ecological-vegetation diversity of Bosnia and Herzegovina, a greater number of Scots and Austrian pine seed facilities is needed. When selecting new seed plants of white and black pine, the focus should be on small stands that grow in extreme conditions.
