Resumo: | Plant genome is an important factor in plant response to arbuscular fungi. This work was designed to evaluate the degree of response to P application and mycorrhizal dependence of different varieties of papaya (Carica papaya L.). The experiment was performed under greenhouse conditions at Embrapa-Centro Nacional de Pesquisa de Mandioca e Fruticultura, Cruz das Almas, BA, Brazil, using seedlings of four varieties, six rates of P: 0, 20, 40, 80, 140 and 280 mg dm-3, and three fungi treatments (one control uninoculated and inoculation with Glomus clarum or Gigaspora margarita). The following parameters were estimated: rate of P for maximum mycorrhizal efficiency; T' value; P benefit, mycorrhizal benefit, symbiotic efficiency, and mycorrhizal dependence. Control plants had a quadratic response to applied P, while those inoculated had a root-quadratic response with a great increment in growth at lower rates; phosphorus benefit was higher in Sunrise Solo and Improved Sunrise Solo - Line 72/12 varieties, while the other two varieties showed a higher mycorrhizal benefit, resulting in a higher symbiotic efficiency. Papaya varieties showed the following classification of mycorrhizal dependency: Baixinho de Santa Amália = Tainung no 1 > Sunrise Solo = Improved Sunrise Solo - Line 72/12. Mycorrhizal dependence related with the capability of the variety to produce roots. |

Avaliou-se, neste trabalho, a resposta a fósforo e o grau de dependência micorrízica de variedades de mamoeiro (Carica papaya L.). O experimento foi realizado em casa de vegetação da Embrapa-Centro Nacional de Pesquisa de Mandioca e Fruticultura, com quatro variedades, testando-se seis doses de P: 0, 20, 40, 80, 140, 280 mg dm-3 e três tratamentos fúngicos (um controle não-micorrizado e a inoculação de Glomus clarum ou Gigaspora margarita). Foram estimados os seguintes parâmetros: dose de P para máxima eficiência micorrízica; valor T'; benefício da aplicação do P; benefício micorrízico; eficiência simbiótica, e dependência micorrízica. Plantas não-micorrizadas apresentaram resposta quadrática ao P aplicado e as inoculadas seguiram modelo raiz-quadrático, com grande incremento de matéria seca da parte aérea nas doses baixas; o benefício de P foi maior nas variedades Sunrise Solo e Improved Sunrise Solo - Line 72/12, enquanto as variedades Baixinho de Santa Amália e Tainung no 1 apresentaram benefício micorrízico proporcionalmente maior, resultando em maior eficiência simbiótica. As variedades de mamoeiro apresentaram a seguinte classificação quanto à dependência micorrízica: Baixinho de Santa Amália = Tainung no 1 > Sunrise Solo = Improved Sunrise Solo - Line 72/12. A maior ou menor dependência relacionou-se com a capacidade da variedade em produzir raízes.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraTrindade, Aldo VilarSiqueira, José OswaldoAlmeida, Florício Pinto de2001-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6283Pesquisa Agropecuaria Brasileira; v.36, n.12, dez. 2001; 1485-1494Pesquisa Agropecuária Brasileira; v.36, n.12, dez. 2001; 1485-14941678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6283/3348info:eu-repo/semantics/openAccess2010-08-12T16:23:25Zoai:ojs.seer.sct.embrapa.br:article/6283Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-08-12T16:23:25Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
