Resumo: The aim of the study was to evaluate the initial development of different provenances and the influence of base fertilizer and coverage on growth of Cedrela fissilis seedlings. Provenances of seeds were collected in Lapa, PR, Fernandes Pinheiro, PR and Itaara, RS. After germination, the seedlings were transplanted to plastic bags of 500 cm³, filled with commercial substrate. Total height (h), stem diameter (sd), and ratio h/sd seedlings were measured after 150 days of transplanting. Seedlings of Fernandes Pinheiro received basic fertilization after transplantation (0, 2, 4, 6 and 8 g dm-3  Osmocote®) and cover (3 and 6 g L-1, respectively, of Peter’s® and urea). The provenance and doses of controlled-release fertilizer influenced early development of Cedrela fissilis seedlings. Itaara provenance showed better seedlings growth. Cedar seedlings showed good growth when incorporated into the substrate 5 g dm-3 Osmocote® and, in addition, applied in topdressing 3 g L-1 of Peter’s®. Urea topdressing is rarely recommended for cedar seedlings.

Após a germinação, as plântulas foram repicadas para sacos plásticos de 500 cm³, preenchidos com substrato comercial. Após 150 dias da repicagem avaliou-se altura total (h), diâmetro do colo (dc) e relação h/dc das mudas. Após as plântulas de Fernandes Pinheiro serem repicadas, avaliouse também o efeito da adubação de base (0, 2, 4, 6 e 8 g dm-3 de Osmocote®) e de cobertura (3 e 6 g L-1, respectivamente, de Peter’s® e ureia). A procedência e as doses do fertilizante de liberação controlada influenciaram no desenvolvimento inicial das mudas de Cedrela fissilis. A procedência de Itaara apresentou melhores resultados de crescimento das mudas. As mudas de cedro apresentam bom crescimento quando foi incorporado ao substrato 5 g dm-3 de Osmocote® e em adubação de cobertura 3 g L-1 de Peter’s®. A adubação de cobertura com ureia é pouco indicada para mudas de cedro.Embrapa Florestas2021-11-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/96610.4336/2016.pfb.36.85.966Pesquisa Florestal Brasileira; v. 36 n. 85 (2016): jan./mar.; 17-24Pesquisa Florestal Brasileira; Vol. 36 No. 85 (2016): jan./mar.; 17-241983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/966/474Copyright (c) 2016 Marcio Carlos Navroski, Erasmo Luis Tonett, Marcos Vinicius Mazzo, Taciana Frigotto, Mariane de Oliveira Pereira, Luan Vieira Galvanihttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessNavroski, Marcio CarlosTonett, Erasmo LuisMazzo, Marcos ViniciusFrigotto, TacianaPereira, Mariane de OliveiraGalvani, Luan Vieira2021-11-17T13:34:26Zoai:pfb.cnpf.embrapa.br/pfb:article/966Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2021-11-17T13:34:26Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
