Resumo: | ABSTRACT Environmental factors, especially light, temperature, and edaphic conditions are of great importance for the establishment of plant communities. In areas degraded by deforestation, these factors can vary greatly, which may affect the recolonization of the typical populations in the altered area. This study evaluated the development of seedlings of pioneer mangrove species under different levels of shading in soil substrate degraded by deforestation, aiming to assess the effect of deforestation on the recolonization of mangrove forests, which may be of help in the production of seedlings and recovery of deforested areas. The study was conducted in the municipality of Acaraú in the state of Ceará, Brazil. The species Avicennia schaueriana Stapf and Leechm. ex Moldenke (1939) and Laguncularia racemosa C. F. Gaertn (1807) were used in the study, and the substrate was collected from an area impacted by deforestation. The propagules and seedlings were exposed to full sun and 30, 50 and 70% shading. The results revealed that the treatment at full sun had the lowest germination rate of 86.66% for L. racemosa. Seedlings of both species showed a significant difference and better quality between shading treatments and full sun. The height of the seedlings showed a correlation above -0.90 with ambient temperature. L. racemosa tested in full sun had a viable seedling reduction of 50% and A. schaueriana was superior. It is concluded that the natural regeneration of a mangrove area can be compromised under the conditions of total deforestation with high sun exposure and degraded soils. Human intervention in providing 50% shading is essential for the development of seedlings and regeneration of the area impacted by deforestation. |
