- Abstract
Studies on the formation of fruit tree seedlings provide information that helps in the production system of the species. The objective was to evaluate the effects of shading levels and substrates in the formation of rose apple seedlings. Environments with shading levels of 0% (full sunlight), 18%, 35% and 50% were evaluated. Four alternative substrates from the combinations of soil, bovine manure, Bioplant®, fine sand, and superfine vermiculite were used. A completely randomized design was used to evaluate the substrates, with five replicates of five seedlings and because there were no replicates of the cultivation environments, a joint analysis was carried out, allowing the comparison of the seedling production environments. Rose apple seedlings produced in protected environments had higher height, diameter, and dry mass. Substrates with a higher percentage of bovine manure resulted in the higher growth rate of the seedlings. The production of rose apple seedlings under full sunlight is not feasible. Thus, the production environment with 35% shading associated with the substrate consisting of 0% soil + 45% bovine manure + 20% Bioplant® + 20% fine sand + 15% superfine vermiculite should be recommended for the production of rose apple seedlings.
