Resumo: The objective of this work was to define the best doses of Osmocote® for Apuleia leiocarpa seedling production for 60 and 90 days residence in the seedling nursery after the transplanting and to observe the chlorophyll index response of the seedlingsduring the studying period. The experimental design used was completely randomized, with five treatments and ten repetitions. The treatments consisted of increasing doses of Osmocote® ( 0, 3, 6, 9 e 12 kg m-3 of substratum). There chlorophyll index, seedlingdiameter and height at 60 and 90 days after transplantation, leaf area, aerial part dry mass, root length and dry mass at 90 days after transplantation. Considering the average values of the points of maximum technical efficiency, seedling diameter and height, it was concluded that the best dosage of Osmocote® for A. leiocarpa seedling production, in a period of 60 and 90 days after transplantation are 7.97 and 7.73 kg of Osmocote® m-3 of substratum, respectively. The chlorophyll index demonstrated quadratic behavior for Osmocote® doses and positive correlation with the variables height and seedling diameter.

O delineamento experimental utilizado foi o inteiramente casualizado, sendo constituído de cinco tratamentos, e dez repetições. Os tratamentos consistiram em doses crescentes de Osmocote® ( 0, 3, 6, 9 e 12 kg m-3 de substrato).Avaliou-se o índice de clorofila, diâmetro do colo e altura das mudas aos 60 e 90 dias após transplante (DAT), área foliar, massa seca da parte aérea, comprimento e massa seca das raízes aos 90 DAT. A partir dos valores médios dos pontos de máximaeficiência técnica, de diâmetro de colo e altura das mudas, concluiu-se que a melhor dose de Osmocote® para a produção de mudas de A. leiocarpa é de 7,94 e 7,73 kg de Osmocote® m-3 de substrato, para um período de permanência em viveiro de 60 e 90 diasapós o transplantio, respectivamente. O índice de clorofila demonstrou comportamento quadrático frente às doses de Osmocote® e correlação positiva com as variáveis altura e diâmetro do colo das mudas.Embrapa Florestas2013-03-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/41910.4336/2013.pfb.33.73.419Pesquisa Florestal Brasileira; v. 33 n. 73 (2013): jan./mar.; 19-25Pesquisa Florestal Brasileira; Vol. 33 No. 73 (2013): jan./mar.; 19-251983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/419/pdf_33Pias, Osmar Henrique de CastroCantarelli, Edison BisogninBerghetti, JulianoLeschewitz, RogérioKluge, Elizandro RicardoSomavilla, Lucindoinfo:eu-repo/semantics/openAccess2017-04-28T12:53:59Zoai:pfb.cnpf.embrapa.br/pfb:article/419Revistahttps://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:2017-04-28T12:53:59Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
