Resumo: Fusarium verticillioides (F. moniliforme Sheldon) is a fumonisin producing corn (Zea mays L.) pathogen, harmful in human and animal health. Concerning the promising use of natural mechanisms of plant defense in phytopathogen control, the anti-F. moniliforme activity of amylase and protease inhibitors in corn hybrids AG-5011 and AG-9010 was evaluated during germination. The profile of inhibitory activity was followed at t0, t12, t24, t36, t48 and t60 of germination, determining enzyme inhibitory activities in the ground kernels. The amylase inhibitor activities increased during germination, where the hybrids AG-5011 showed activity pick at t60 (115,2 UIA/g), while the precocious hybrid AG-9010 the pick occurred at t36 (172,8 UIA/g). The protease inhibitor activity decreased during the germination, with the maximal activity between t0 and t12, which corresponded to 3080,5 UIP/g (AG-5011) and 2839,8 UIP/g (AG-9010). The data showed indicated probable role of enzymatic inhibitors in the plant germination and natural mechanism of defense against F. moniliforme in corn.

Considerando que os mecanismos naturais de defesa sejam ferramentas promissoras no controle de fitopatógenos, avaliou-se a atividade anti-F. moniliforme dos inibidores de amilase e protease presente nos híbridos AG-5011 e AG-9010, durante a germinação. O perfil de atividade foi avaliado, triturando-se os grãos nos tempos t0, t12, t24, t36, t48 e t60 de horas germinação e determinou-se a atividade inibitória na farinha obtida. O inibidor de amilase aumentou com a germinação, sendo que no híbrido AG-5011 atingiu pico de atividade em t60 (115,2 UIA/g), enquanto que no híbrido precoce AG-9010 ocorreu maior atividade em t36 (172,8 UIA/g). O inibidor de protease diminuiu durante a germinação, ocorrendo atividade máxima entre t0 e t12, correspondente a 3080,5 UIP/g (AG-5011) e 2839,8 UIP/g (AG-9010). Os resultados obtidos indicaram possível desempenho de inibidores enzimáticos na germinação e mecanismo de defesa natural contra F. moniliforme no milho.UEL2009-04-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/210510.5433/1679-0359.2002v23n2p249Semina: Ciências Agrárias; Vol. 23 No. 2 (2002); 249-258Semina: Ciências Agrárias; v. 23 n. 2 (2002); 249-2581679-03591676-546Xreponame:Semina.
