Resumo: The quality of the seedling produced is directly related to substrate composition, so it is essential to select constituents with adequate characteristics. The objective of this study was to evaluate Eucalyptus urophylla, Peltophorum dubium and Eremanthus erythropappus seedlings and to relate the physical and chemical characteristics of the formulated substrates to their quality. For each species, an experiment was carried out in a completely randomized design (CRD), consisting of five treatments, five replicates, and plots composed of 20 seedlings. In order to evaluate the quality of the seedlings, the biometric variables were measured and, as a qualitative analysis, the ease to remove the seedlings from the tubes (ERT) and root aggregation to the substrate (AGGR) were evaluated. Seedlings produced in the substrates formulated with alternative constituents showed higher values when compared to seedlings produced with commercial substrate, for most of the analyzed variables. Coffee husk can be applied in the production of seedlings of P. dubium and E. urophylla. For the formation of E. erythropappus seedlings, none of the formulations tested are recommended.

Objetivou-se avaliar a produção de mudas de Eucalyptus urophylla, Peltophorum dubium e Eremanthus erythropappus e também relacionar as características físicas e químicas dos substratos formulados com a qualidade das mudas formadas. Para cada espécie foi conduzido um experimento, instalado em delineamento inteiramente casualizado (DIC), constituídos por cinco tratamentos, cinco repetições, e parcelas compostas por 20 mudas. Para avaliação da qualidade das mudas, foram mensuradas as variáveis biométricas e como análises qualitativas, foram avaliadas a facilidade de retirada das mudas do tubete (ERT) e a agregação das raízes ao substrato (AGGR). As mudas produzidas nos substratos formulados com constituintes alternativos apresentaram valores superiores quando comparados às mudas produzidas com o substrato comercial, para a maioria das variáveis analisadas. A casca de café pode ser aplicada na produção de mudas de P. dubium e de E. urophylla. Já para a formação de mudas de E. erythropappus, não se recomenda nenhuma das formulações testadas.Universidade Federal do Paraná (UFPR), Faculdade de Florestas2022-03-14T16:33:10Z2022-03-14T16:33:10Z2021-06info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfSILVA, O.
