Avaliação da morfologia dos sistemas radicais de plantas de regeneração do sobreiro através de imagem digital

The purpose of this study is to compare rooting patterns, namely root systems morphology of trees planted from seedlings with root systems morphology of seeded trees. The evolution of root systems can influence growth in future therefore it is important to monitor it. Data was collected in a stand installed in 1997. The evaluation of the root morphology was done using digital image analysis. Root system morphology and distribution of roots in different horizons was evaluated in eight trenches (4 trees planted + 4 trees seeded). The results show significant differences showing planted trees larger root area than seeded trees. It wasn’t found significant differences in the root system shape between planted and seeded trees.
