Levantamento da micoflora presente em grãos ardidos e sementes de milho

Abstract: In maize crop, ear rot caused by fungi is one of the main responsible for quality and production losses, mainly because of the development of the so called discolored grains. The purpose of this study was to identify the mycoflora present in gra ins a nd kernels produ ced in different regions and clima tic zones of Brazil du ring su mmer and winter harvest and relate the occurrence of fungi with such parameters. T he identifica tion of the fu ngi wa s done by the filter pa per with freezing method. Two hundred… Show more

“…Although in Brazil high levels of aflatoxins and incidence of Aspergillus spp. have been reported (Machinski et al 2001;Ramos et al 2010), we found a lower incidence of this fungal genus compared to previous reports. The mycotoxins aflatoxins and ochratoxins, which are mainly produced by Aspergillus and Penicillium, respectively, were not quantified in this study.…”

“…O mesmo foi verificado por Ramos et al (2010), que, em levantamento de fungos presentes em grãos ardidos e sementes de milho, observaram alta incidência dos gêneros Fusarium e Penicillium, principalmente na safra de verão. Azevedo et al (1994) e Orsi et al (1995) observaram que o gênero mais encontrado no milho recém-colhido foi o Fusarium, seguido por Aspergillus e Penicillium.…”

“…Houve interação de épocas de semeadura e híbridos, para os fungos Fusarium sp. e Nigrospora sp., sendo a incidência de Fusarium maior em grãos do híbrido Celeron TL, na safra de verão, como também observado por Ramos et al (2010). No entanto, para o híbrido Status TL, a incidência de Fusarium sp., e também Nigrospora sp., foi maior na safrinha (Tabela 2).…”

“…and Phoma sp., which were observed only on the first experiment and the genres Colletotrichum, Curvularia, and Nigrospora, which appeared only on the second experiment. published reporting the problems provoked by this fungus, that has as main inoculum sources the infected rests of the maize crop and also the soil (FESSEL et al, 2003;CASA et al, 2007;RAMOS et al, 2010;HENNING et al, 2011 andHUSSAIN et al, 2013). The spore dissemination occurs because of the wind and insects, and the period of higher susceptibility occurs between seven and ten days after the pollination of the stigmas.…”
