Resumo: | Cordia trichotoma is a native species with economic potential due to its wood quality. However, knowledge regarding the production of quality seedlings of the species is still incipient. Thus, the objective was to evaluate the use of agricultural residues as a substrate compound and the shading intensities in the nursery phase for Cordia trichotoma seedlings production. Five substrate compositions were tested: S1 (80% CF-coconut fiber- and 20% CCC-carbonized coffee husks); S2 (60% FC and 40% CCC); S3 (80% FC and 20% CAC-carbonized rice husk); S4 (60% FC and 40% CAC); S5 (100% commercial substrate). Also, we tested four different shading levels: 0%; 30%; 50%;80%. The experiment was in a factorial design with a completely randomized design. At 180 days, we measured seedling height, stem diameter, shoot dry mass, and root system dry mass and calculated the robustness index and Dickson Quality Index. We observed that carbonized husks provided lower growth than the use of a commercial substrate in all analyzed variables. Furthermore, shading provided negative quadratic growth in the analyzed variables. Thus, it is recommended the use of commercial substrate and shading of 50% in seedlings of Cordia trichotoma. |

No entanto, os conhecimentos quanto a produção de mudas de qualidade da espécie ainda são incipientes. Dessa forma, objetivou-se avaliar o uso de resíduos agrícolas como composto de substrato e as intensidades de sombreamento em fase de viveiro, para a produção de mudas de Cordia trichotoma. Foram testadas cinco composições de substrato: S1 (80% FC-fibra de coco- e 20% CCC-casca de café carbonizada); S2 (60% FC e 40% CCC); S3 (80% FC e 20% CAC-casca de arroz carbonizada); S4 (60% FC e 40% CAC); S5 (100% substrato comercial). E quatro diferentes níveis de sombreamento: 0%; 30%; 50%; 80%. O delineamento experimental foi inteiramente casualizado em esquema fatorial. Foram mensurados aos 180 dias, a altura das mudas, o diâmetro de coleto, a massa seca da parte aérea, a massa seca do sistema radicular e calculados o índice de robustez e o Índice de Qualidade de Dickson. Foi observado que o uso de cascas proporcionou crescimento inferior ao uso de substrato comercial, em todas as variáveis analisadas. Ademais, o sombreamento proporcionou comportamento quadrático negativo nas variáveis analisadas. Assim, recomenda-se a utilização de substrato comercial e de sombreamento de 50%, em mudas de Cordia trichotoma.Universidade Federal de Santa Maria2023-09-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/6901010.5902/1980509869010Ciência Florestal; Vol. 33 No. 3 (2023): Publicação Contínua; e69010Ciência Florestal; v. 33 n. 3 (2023): Publicação Contínua; e690101980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/69010/61682Copyright (c) 2023 Ciência Florestalhttp://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessAlmeida, Rodolfo Soares deCunha, Fernanda LeiteRossi, Jamille AlonsoMelo, Lucas Amaral de2023-09-19T21:44:05Zoai:ojs.pkp.sfu.ca:article/69010Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2023-09-19T21:44:05Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
