Resumo: | Three progenies of Hevea, with different levels of resistance to isolation of M. ulei (UNA) were studied. The progenies were: Fx 25 (moderately susceptible), Fx 2804 (highly susceptible) and P10 (resistant). The inoculation was made at the fourth flushing, with six to eight day-old leaflets. The progenies were maintained in a growth chamber. After 24, 72 and 144 hours, inoculated and noninoculated leaflets were collected to determine phenol, anthocyanin and chlorophyll contents. Progenies Fx 25 and Fx 2804 showed low phenol levels, decreasing levels of chlorophyll and a great number of injuries and sporulation. Progenie P10 showed high levels of phenol and chlorophyll, compared to the control. It did not show any injury. The anthocyanin levels decreased in all progenies. Consequently, Hevea resistance to M. ulei infection seems to be related to variations of leaf phenol levels. |

A inoculação foi realizada no quarto lançamento, com folfolos de seis a oito dias de idade. As progênies foram mantidas em câmara de crescimento. Após 24, 72 e 144 horas foram feitas coletas dos folíolos inoculados e não inoculados e realizou-se a quantificação do teor de fenóis, antocianina e clorofila. Observou-se que as progênies Fx 25 e Fx 2804 apresentaram baixos níveis de fenóis e decréscimo no nível de clorofila, grande número de lesões e esporulação. A progênie P10 apresentou alto teor de fenóis com relação à testemunha, bem como de clorofila, não apresentando lesões. O nível de antocianina decresceu em todas as progênies. Assim, a resistência da seringueira à infecção por M. ulei parece estar associada à variação do teor de fenóis em suas folhas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPita, Francisco Antônio de OliveiraJunqueira, Nilton T.V.Alfenas, Acelino CoutoCano, Marco Antônio Oliva2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/13608Pesquisa Agropecuaria Brasileira; v.25, n.8, ago. 1990; 1193-1200Pesquisa Agropecuária Brasileira; v.25, n.8, ago. 1990; 1193-12001678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/13608/7715info:eu-repo/semantics/openAccess2014-04-17T14:39:57Zoai:ojs.seer.sct.embrapa.br:article/13608Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-17T14:39:57Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
