FUNGOS ASSOCIADOS ÀS SEMENTES DE <i>Enterolobium contortisiliquum</i>: ANÁLISE DA INCIDÊNCIA, CONTROLE E EFEITOS NA QUALIDADE FISIOLÓGICA COM O USO DE EXTRATOS VEGETAIS

Abstract: http://dx.doi.org/10.5902/1980509821090Os fungos são os principais micro-organismos associados às sementes, podendo causar danos, tanto na fase de campo, como também na pós-colheita e durante o armazenamento. Nesta última fase, a deterioração pode ocorrer pela ação específica de fungos, afetando a qualidade fisiológica das sementes. A utilização de extratos de plantas com propriedades antimicrobianas são alternativas ecológicas e promissoras para substituir a proteção promovida pela aplicação de fungicidas. Ob… Show more

“…In general, through the obtained results, it can be inferred that the ethanolic extract of A. colubrina is a viable alternative in the control of mycoflora associated with maize seeds, favoring their germinability, due to the presence of substances with fungicidal properties in its composition. For MEDEIROS et al (2016), seeds predisposed to the action of microorganisms, when treated, reduce the ability of phytopathogens to survive and enhance seed longevity, their germinative power and the vigor of future plants.…”

“…For the obtention of A. colubrina extract, the cold extraction method was used, as proposed by MEDEIROS et al (2016), in which the plant material (leaves) was dried in an oven at 40 °C for 72 h and, subsequently, crushed in a knife mill to obtain the plant powder; 150 g of plant powder were used, immersed in a beaker containing 0.5 L of absolute ethanol for 72 h at room temperature (25 ± 2 °C); the solution was filtered through filter paper. After the procedure, the solvent was left for 10 h in an oven with a ventilation system at 70 °C for the obtention of the crude ethanolic extract.…”

“…Foram observados valores de Coeficiente de Variação (CV) de 21,75% a 60,87% (Tabela 2). De acordo com Pimentel-Gomes e Garcia (2002), apesar de experimentos em condições bem controladas, como em laboratório, resultarem em baixos CV, isso não é regra geral, o que tem sido verificado em outros trabalhos com sanidade de sementes (AIMI et al, 2016;MEDEIROS et al, 2016). De maneira geral, Fusarium spp.…”

“…Por isso, estudar a qualidade sanitária associada à qualidade fisiológica das sementes é tão relevante atualmente (CARMO et al, 2017). Como os fitopatógenos fúngicos associados às sementes são geralmente encontrados no interior e/ou na superfície do tegumento (MEDEIROS et al, 2016), a aplicação de fungicidas químicos pode ser usada como alternativa para controle.…”
