Resumo: The establishment of exotic forest species in Brazil may show  dependence to ectomycorrhizal association, which increases the resistance of seedlings to stress after the initial planting in the  field, favoring the maintenance of harshseedlings under  adverse conditions. The study aimed to evaluate the effect of  applying the eucalyptus essential oil in ectomycorrhizal  colonization on growth of Eucalyptus grandis seedlings in greenhouse conditions. The treatments consisted of five  concentrations of the Eucayptus grandis essential oil and two  ectomycorrhizal isolates, in addition to the control treatment  without inoculation. It was used a completely randomized  design with eight repetitions. Ninety days after transplanting  the eucalyptus seedlings were evaluated: height (cm), stem  diameter (mm), dry massof shoots and roots (mg) and percentage of ectomycorrhizal colonization. The eucalyptus  essential oil was efficient in stimulating ectomycorrhizal  colonization of eucalyptus seedlings, resulting in significant  increases in dry weight of shoots of mycorrhizal seedlings,  showing doseresponse effect, depending on the ectomycorrhizal used.doi: 10.4336/2011.pfb.31.67.235

O trabalho objetivou avaliar o  efeito da aplicação do óleo essencial de eucalipto na  colonização ectomicorrízica e no crescimento de mudas de  Eucalyptus grandis, em condições de casa de vegetação. Os tratamentos foram constituídos por cinco concentrações do óleo  essencial de Eucayptus grandis e dois isolados  ectomicorrízicos, além dos tratamentos controle sem  inoculação. Utilizou-se delineamento experimental inteiramente casualizado com oito repetições. Noventa dias após o  transplante das plântulas de eucalipto para tubetes foram  avaliados os parâmetros: altura da muda (cm), diâmetro do  colo (mm), massa seca da parte aérea e raízes (mg) e  percentual de colonização ectomicorrízica. O óleo essencial de  eucalipto mostrou-se eficiente no estímulo à colonização  ectomicorrízica das mudas de eucalipto, resultando em  aumentos significativos na colonização e na massa fresca e  massa seca da parte aérea das mudas micorrizadas,  apresentando resposta de dose-efeito, dependendo do isolado  ectomicorrízico utilizado.doi: 10.4336/2011.pfb.31.67.235Embrapa Florestas2011-09-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/mswordimage/jpeghttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/260Pesquisa Florestal Brasileira; v. 31 n. 67 (2011): jul./set.; 235Pesquisa Florestal Brasileira; Vol. 31 No. 67 (2011): jul./set.; 2351983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/260/222https://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/260/980https://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/260/981Steffen, Ricardo BemficaAntoniolli, Zaida InêsSteffen, Gerusa Pauli KistJacques, Rodrigo Josemar SeminotiEchkardt, Daniel Pazzinidos Santos, Marcos LeandroSantana, Natielo Almeidainfo:eu-repo/semantics/openAccess2017-04-28T13:06:26Zoai:pfb.cnpf.embrapa.br/pfb:article/260Revistahttps://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:2017-04-28T13:06:26Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
