Resumo: | The objective of this work was to evaluate the initial growth and biomass partitioning of mulungu (Erythrina velutina Willd.) seedlings under different rates of phosphorus in the presence and absence of arbuscular mycorrhizal fungi (FMA’s). A randomized blocks design in a 5 x 2 factorial arrangement was used, with four replicates and three plants per plot. Treatments consisted of five phosphorus rates (0, 50, 100, 150 and 200 mg.Kg soil-1), using as source the superphosphate fertilizer, and presence or absence of FMA’s. At 98 days after sowing (DAS), shoot height, stem diameter, leaf number, leaf chlorophyll index, leaf dry matter, stem dry matter, root dry matter, leaf area, Dickson quality index and height/stem diameter ratio were evaluated. The phosphorus rate of 200 mg.kg-1 proved to be the most efficient for production of Erythrina velutina seedlings, but with a significant reduction in the biological association of this plant with rhizobacteria. Biomass distribution within the different parts of the plants did not change with distinct rates of P, and there were no benefits in the use of FMA’s until 98 DAS. |

Foi utilizado o delineamento experimental em blocos ao acaso, num esquema fatorial 5 x 2, com quatro blocos e três plantas por unidade experimental. Os tratamentos foram compostos pela combinação de cinco doses de fósforo (0, 50, 100, 150 e 200 mg de P.kg de solo-1), utilizando-se como fonte o adubo superfosfato simples, e presença ou ausência de FMA’s. Aos 98 dias após a semeadura (DAS) foram avaliadas as variáveis: altura da parte aérea, diâmetro do colo, número de folhas, índice de conteúdo de clorofila foliar, matéria seca das folhas, caules e raízes, área foliar, índice de qualidade de Dickson e relação altura/diâmetro do colo. A dose de 200 mg.kg-1 de P mostrou- se a mais eficiente para produção de mudas de mulungu, mas com uma diminuição significativa na associação biológica dessa espécie com rizobactérias. A distribuição de biomassa entre os órgãos das mudas não foi alterada entre diferentes doses de P, não havendo benefícios na utilização de FMA’s até aos 98 DAS.Embrapa Florestas2014-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/64210.4336/2014.pfb.34.80.642Pesquisa Florestal Brasileira; v. 34 n. 80 (2014): out./dez.; 407-415Pesquisa Florestal Brasileira; Vol. 34 No. 80 (2014): out./dez.; 407-4151983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/642/391Leite, Tiago de SousaFreitas, Rômulo Magno Oliveira deDombroski, Jeferson Luiz DallabonaLeite, Moadir de SousaRodrigues, Mara Raquel de Oliveirainfo:eu-repo/semantics/openAccess2017-04-28T12:49:00Zoai:pfb.cnpf.embrapa.br/pfb:article/642Revistahttps://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:2017-04-28T12:49Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
