- Abstract
The production of jatoba (Hymenaea courbaril L.) seedlings is essential for the conservation and restitution of their natural habitat. However, the production of seedlings of native species is still little studied. Therefore, the objective of this study was to evaluate the effect of different levels of pruning and hydrogel doses on the initial growth of jatoba under shading. We used jatoba seedlings with 90 days of age in a factorial scheme consisting of three levels of root pruning (0.0, 25.0, and 50.0%) and five hydrogel doses (0.0, 2.0, 4.0, 6.0 and 8.0 g L-1 substrate) totalizing 15 treatments. At 105 days after transplanting in the greenhouse, morphometric parameters and growth rates were evaluated. Seedlings submitted to root pruning of 25.0% showed greater growth after transplanting to plastic bags. The hydrogel also showed a positive effect on the morphometric variables evaluated. The combined effects of 25.0% of root pruning level and doses of hydrogel in the range of 3.0 to 4.0 g L-1 exerted positive effects on the growth of morphometric variables. These isolated or combined techniques can be employed in a nursery to prolong the maintenance time of jatoba seedlings.
