- Abstract
Root system characteristics were studied in order to evaluate the performance of eucalyptus clones in edaphoclimatic conditions of Vitória da Conquista, Bahia, Brazil. Two experiments were carried out. First, in a nursery, seedlings had their roots pruned and were planted in transparent tubes, outlined in quadrants, for evaluating root regeneration potential (RRP) and the dry matter partitioning from shoot to roots. 30 days after planting, AEC 144 and CO 520 were the clones with highest RRP, although CO 520 is similar to the other three clones. AEC 144 showed a tendency of better performance in dry matter partitioning from shoot to roots. The second experiment was carried out in the field. Six months after planting, plant height, stem diameter, leaf area, number of leaves, main root length, shoot and root dry matter, and soluble sugar, reducing sugar, protein and amino acid contents in roots were determined. There were no significant differences in all characteristics evaluated among the clones. Despite the differences related to RRP and dry mass partitioning, we concluded that the clones have characteristics which lead to a similar plant performance in the field, in the edaphoclimatic conditions of Vitória da Conquista.
