Resumo: The potential of ectomycorrhizal fungi to promote plant growth and the mycorrhization control may contribute to important progress towards the exploitation of these fungi commercially. The objective of this work was to evaluate the efficiency of ectomycorrhizal isolates on root colonization, P uptake and growth of Eucalyptus dunnii seedlings under different levels of phosphorus applied. Inocula of the ectomycorrhizal isolates, INRA-Cou (Paxillus involutus), UFSC-Hg93 (Hysterangium gardneri), UFSC-Pt116 (Pisolithus microcarpus) and UFSC-Ch163 (Chondrogaster angustisporus), were aseptically produced in a peat-vermiculite mixture supplemented with liquid culture medium. Plants were grown in a similar substrate supplemented with macro- and micronutrients, under different levels of phosphorus: 0, 0.25, 0.50, 1.00, 2.00, 4.00, and 8.00 mg per plant. The isolates UFSC-Pt116 and UFSC-Ch163 promoted higher root colonization, higher P uptake and plant growth, as determined by plant height and dry matter. Levels of 0.50 and 1.00 mg of P per plant promoted a significant mycorrhizal colonization and an adequate plant growth. The isolates UFSC-Ch163 and UFSC-Pt116 represent a promising alternative for a controlled mycorrhization programme of E. dunnii.

O objetivo deste trabalho foi avaliar a eficiência de isolados de fungos ectomicorrízicos na colonização radicular, absorção de P e no crescimento de mudas de Eucalyptus dunnii, sob diferentes doses de fósforo. O inóculo dos isolados fúngicos INRA-Cou (Paxillus involutus), UFSC-Hg93 (Hysterangium gardneri), UFSC-Pt116 (Pisolithus microcarpus) e UFSC-Ch163 (Chondrogaster angustisporus) foi produzido assepticamente numa mistura turfa-vermiculita-meio de cultura. As plantas foram cultivadas num substrato de igual composição, suplementado com macro e micronutrientes, e diferentes doses de fósforo: 0, 0,25, 0,50, 1,00, 2,00, 4,00 e 8,00 mg por planta. Os isolados UFSC-Pt116 e UFSC-Ch163 promoveram maior colonização radicular, absorção de P e crescimento das plantas, medido pela altura e massa de matéria seca. A colonização micorrízica foi inibida pelo aumento das doses de fósforo. As doses de 0,50 e 1,00 mg de P por planta mostraram-se mais adequadas em compatibilizar a colonização radicular com um bom crescimento das mudas. Os isolados UFSC-Ch163 e UFSC-Pt116 são promissores em um programa de micorrização controlada de E. dunnii.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária Brasileirade Souza, Luiz Afonso BorgesSilva Filho, Germano Nunesde Oliveira, Vetúria Lopes2004-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6780Pesquisa Agropecuaria Brasileira; v.39, n.4, abr. 2004; 349-355Pesquisa Agropecuária Brasileira; v.39, n.4, abr. 2004; 349-3551678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6780/3836info:eu-repo/semantics/openAccess2014-07-16T18:07:48Zoai:ojs.seer.sct.embrapa.br:article/6780Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-16T18:07:48Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
