Abstract

There are few studies related to the development and quality of seedlings of CopaiferalangsdorffiDesf., especially in relation to adaptation to internships successional and fiel devaluation for prolonged periods. this sense, the objective was to evaluate the initial development and quality of seedlings of CopaiferalangsdorffiiDesf., under nursery shading levels, as well as monitoring of field growth in an area of forest recomposition. The study was conducted in two stages, being the first conducted in a nursery in a completely randomized design and 15 repetitions. At the end of the 50 days after the emergency, the seedlings were subjected to shading levels: full sun, 50% artificial shading and a natural shade (Cerrado strictsense). Evaluations were performed at 60, 81, 102, 123 and 144 days after emergence. The second phase was carried out in a project of forest recomposition of a degraded area, with the planting of seedlings produced in full sunlight. Field assessments were carried out in the implantation and at 165, 520 and 1302 days. In the first stage, the seedlings submitted to the full sun condition presented a superior quality pattern in relation to the shaded conditions, thus, the most indicated for field planting in the recovery of degraded forest areas.Under field conditions, plants showed slow growth, reaching 72 cm height at 1302 days and 50% survival from 520 days. Thus, the level of shading, under nursery conditions, which provided better initial development of the seedlings of CopaiferalangsdorffiiDesf., it was the full sun, due to the qualitative performance of the seedlings and the low operating cost. In addition, under field conditions, the CopaiferalangsdorffiiDesf., has been shown to have development median and low survival rate.
