Sobrevivência e crescimento inicial de mudas de Pinus taeda L. com diferentes diâmetros do colo

The aim of this research was to evaluate the survival and growth of Pinus taeda seedlings produced in containers and bare root with different collar diameters. Two trials were established in a poor drained area located in the Corrientes province, Argentina. The experimental design was randomized complete blocks, with 3 replications and experimental units with 64 seedlings with double lines buffer. The treatments evaluated on the trial 1 were seedlings produced in containers with collar diameter of 1,6 mm; 2 mm; 3mm and 4 mm and on the trial 2 were bare root seedlings with collar diameters of 3 mm; 4 mm; 5 mm and 6 mm. At 4-year-old the seedlings produced in containers did not showed significant differences in survival and growth however in the bare root seedlings production, the seedlings with 4 and 5 mm showed the best survival. No significant differences in growth were detected for all the treatments. For both types of seedling production the collar diameter did not showed significant influence in field growth.
