Abstract

Given the relevance of studies focusing on the production of native forest seedlings and biodegradable containers and the use of new inputs to increase seedling survival in the field, the aim of this work was to evaluate the effect of TNT bags and hydroretentive polymer on the production of Sobrasil seedlings. The experiment occurred in the greenhouse, at the Federal Institute of Espírito Santo, Alegre campus. Six treatments were evaluated, differing between container and addition or not of hydrogel, evaluating morphological and physiological parameters. The data were processed by analysis of variance at 5% significance, and when they showed significant differences, they were compared using the Tukey test at 5% probability. The results demonstrate that the seedlings produced in TNT bags with and without holes had qualities equal to those in plastic bags. The use of hydrogel was only beneficial when combined with a TNT bag without holes.
