Resumo: | This work was carried out in order to evaluate the initial growth in different conditions of shadings of the species Copernicia alba, Copernicia hospita and Copernicia macroglossa. Initially the seed were soaked in water to a pre-germination, afterward were sowed in tubes (288 ml) filled with substrate (sandy loam + organic compost + vermiculite) in proportion 2:1:1 and kept in full sun, 30%, 50% e 70% shading. It was adopted the completely randomized design, with five repetitions (4 plants/repetition) and five periods of evaluation: 45, 90, 135, 180 and 225 days after sowing, with the factors disposed in a spli-splot measured over time (4 shading levels x 5 evaluation times). Each period of evaluation were measured the following variables: number of leaves, height, stem diameter, foliar area, dry mass of aerial parts and roots, Dickson of quality index. The seedling of Copernicia cultivated in full sun and 30% shading express positive effects in the initial growth with good quality. The largest leaf areas of the species were found in the environment with 30% shading. In face of these results, the obtained data are important and indispensable to establishment of seedling production of quality of Copernicia. |

Inicialmente, as sementes foram embebidas em água para uma pré-germinação, em seguida foram semeadas em tubetes (288 ml) preenchidos com substrato (arisco + composto orgânico + vermiculita) na proporção de 2:1:1 e mantidas a pleno sol, 30%, 50% e 70% de sombreamento. Adotou-se o delineamento inteiramente casualizado com 5 repetições (4 plantas/repetição) e cinco períodos de avaliação 45, 90, 135, 180 e 225 dias após a semeadura, com fatores dispostos em arranjo de parcelas subdivididas no tempo (4 níveis de sombreamento x 5 épocas de avaliação). A cada época de avaliação, foram mensuradas as seguintes variáveis respostas: número de folhas, altura, diâmetro do coleto, área foliar, massa seca das partes aéreas e das raízes e índice de qualidade de Dickson. As mudas de Copernicia cultivadas em pleno sol e 30% de sombreamento expressam efeitos positivos no crescimento inicial com boa qualidade. Os melhores resultados de área foliar das espécies foram encontrados no ambiente com 30% de sombreamento. Diante desses resultados, os dados obtidos são importantes e indispensáveis ao estabelecimento de produção de mudas de qualidade de Copernicia.Universidade Federal de Santa Maria2022-11-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/xmlhttps://periodicos.ufsm.br/cienciaflorestal/article/view/6676310.5902/1980509866763Ciência Florestal; Vol. 32 No. 4 (2022); 2094-2112Ciência Florestal; v. 32 n. 4 (2022); 2094-21121980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/66763/49472https://periodicos.ufsm.br/cienciaflorestal/article/view/66763/52407Copyright (c) 2022 Ciência Florestalhttp://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessViana, Erivanda de OliveiraBezerra, Antonio Marcos EsmeraldoPereira, Diego de SousaLacerda, Claudivan Feitosa deMedeiros Filho, Sebastião2023-04-14T14:10:48Zoai:ojs.pkp.sfu.ca:article/66763Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2023-04-14T14:10:48Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
