Resumo: Seedling of seven forest species were raised in conventional nursery substrate either infested or not with a mixture of arbuscular mycorrhizal fungi (Glomus etunicatum, Gigaspora margarita and Acaulospora scrobiculata) and transplanted into plastic pots with a low-fertility Oxisol amended with low or high NPK-fertilization and with or without re-inoculation. It was found that either inoculation at nursery or at transplanting stage guaranteed high root colonization (>70%), growth response and favorable nutrition after transplant. Growth effects varied with treatments and with plant species. Inoculation benefits for shoot dry matter were as high as 800% for Colvillea racemosa. Reduced growth was observed when seedling non-inoculated at nursery stage were also not inoculated at transplanting, whereas nursery-inoculated ones grew well independently on soil fertility and re-inoculation. Enhanced soil fertility did not increase shoot dry matter yield of Luehea grandiflora, Senna macranthera and Enterolobium contortisiliquum. It increased dry matter of Cecropia pachystachya in the absence of mycorrhiza; of mycorrhizal Senna multijuga and C. racemosa and of Sesbania virgata caused an increase in all treatments. Only C. racemosa did not respond to inoculation at transplanting.

Verificou-se, após 90 dias, que tanto a inoculação na formação quanto a inoculação no transplantio garantiu elevada colonização micorrízica ( > 70%), estimulou o crescimento e aumentou os teores de alguns nutrientes nas plantas. Os efeitos no crescimento variaram entre as espécies e tratamentos, atingindo incrementos de matéria seca de até 800% em Colvillea racemosa. Plantas sem inoculação na formação e no transplantio, apresentaram crescimento reduzido, mesmo no solo com alta fertilidade, enquanto as plantas com inoculação na formação cresceram mais rapidamente, independentemente da reinoculação. A elevação da fertilidade não aumentou a matéria seca da parte aérea de Luehea grandiflora, Senna macranthera e Enterolobium contortisiliquum. Em Cecropia pachystachya aumentou apenas quando as mudas não foram submetidas a inoculação. Em Senna multijuga e em C. racemosa, a matéria seca da parte aérea aumentou quando as mudas foram submetidas a inoculação e em Sesbania virgata, aumentou em todos os tratamentos. Apenas C. racemosa não respondeu à inoculação no transplantio.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraRojas, Enrique PouyuSiqueira, José Oswaldo2000-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5687Pesquisa Agropecuaria Brasileira; v.35, n.1, jan. 2000; 103-114Pesquisa Agropecuária Brasileira; v.35, n.1, jan. 2000; 103-1141678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5687/2791info:eu-repo/semantics/openAccess2010-07-29T18:38:36Zoai:ojs.seer.sct.embrapa.br:article/5687Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-07-29T18:38:36Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
