Description
Summary:Transplanting had significant effects over the development, growth, and quality of Bertholletia excelsa seedlings during the first 165 days of seedling production. [...]shoot pruning resulted in better performance of B. excelsa seedlings to be planted in the field. Among the factors that influence the production process of tree species seedlings, there are: kind of substrate, substrate moisture, substrate porosity, seeds dormancy, temperature, shading and container volume, irrigation, seed quality, fertilization, and seedling management in the nursery (Camargo et al. 2011, Costa et al. 2015, Marques et al. 2018). Currently, there are almost no studies on transplanting methods and techniques to improve seedling quality of B. excelsa. [...]the objective of this study was to test the initial growth and quality B. excelsa seedlings of different sizes in forest nursery. A total of 160 B. excelsa seedlings had their roots pruned and were transplanted. Besides root pruning of all individuals, the seedling were divided in four treatments as described in Figure 1 and Table 1.
