| Sumario: | Growth and production initial characteristics of 6 pioner tree species and 9 advanced successional stages tree species were determined. The 15 species are native of the Ecuadorian Amazon. They were planted in a randomized complete blocks, with two fertilizer treatments (70 days and 180 days were the time of release of nutrients) and one witness. The study site is located in Domomo, Macas, Morona Santiago, Ecuador. Plant growth (height, basal diameter) was measured 7 times during 6 months. Three seedlings partial collections were made to measure the biomass. As result, Nectandra membranaceae is one of the advanced successional species with hard adaptation for growing in broad daylight, as its survival was almost zero. Heliocarpus americanus, Pollalesta discolor and Erythrina poeppigiana were the pionner species with better growth in height, basal diameter and biomass. No significant effects were observed by fertilizer treatments on height growth, basal diameter and biomass during the first three months. The results will serve for selecting the pioneer species more susceptible to produce a dense vegetation cover on degraded soils and the tree species of advanced successional stages. |
