Direct sowing for the implantation of a riparian forest of the lower San Francisco river in Sergipe state, Brazil
Year: 2009
Type: article
Abstract: The present study was undertaken with the goal to evaluate the initial growth of five forest species, after direct sowing in a riparian area at the lower San Francisco River, Sergipe. The experiment was carried out in Santana San Francisco County, SE (10º18”56’ S e 36º52”58’ W), in a randomized block design, with line plantings, alternating pioneer and climax species. The evaluated parameters were: seedlings’ emergence, survival and initial growth by height, base diameter and relative growth. Enterolobium contortisiliquum, Hymenaea courbaril and Cassia grandis showed the best percentages of seedling emergence, while Schinus terebinthifolius and Caesalpinia leiostachya were in the lower percentages. Seedling establishment was affected by specific mass and length of seeds. E. contortisiliquum and H. courbaril were superior to other species in survival at 30 months. C. leiostachya and E. contortisiliquum presented the best growth in height, while S. terebinthifolius had the largest base diameter. S. terebinthifolius had the best relative growth in height and base diameter. The studied species showed potential for the use in the restoration of riparian forests by direct sowing.
