Efeito do armazenamento na energia corporal de juvenis do segundo estádio de Meloidogyne incognita infestados por Pasteuria penetrans

Abstract: Neste trabalho, objetivou-se estudar o efeito do período de armazenamento no teor de lipídios de juvenis do segundo estádio (J2) de M. incognita com endósporos de P. penetrans na infectividade e reprodução em tomateiro. Suspensões de M. incognita contendo ou não endósporos de P. penetrans aderidos à cutícula foram armazenadas por 0, 3, 6, 9 e 12 dias, a 28ºC. Após cada período de estocagem, determinou-se a concentração de lipídios neutros corporais por meio da análise de imagem dos J2 coloridos com o corante "… Show more

“…suggest a possible association with the reaction of oats to the parasitism of M. javanica and M. incognita, necessitating future studies to understand these mechanisms. The effectiveness of genotype selection for cultivation and/or breeding programs depends on the genetic variability and heritability of the parent material associated with the interaction of the genotypes with the different levels of nematode infection (Machado et al, 2015;Rocha et al, 2009). However, there is no accessible information on genetic parameters of resistance of oats towards root-knot nematodes.…”
