Influência da temperatura, umidade, concentração de inóculo de Acidovorax avenae subsp. citrulli e idade do fruto no desenvolvimento da mancha-aquosa em melão

Abstract: Foram analisadas as influências da temperatura (15, 20, 25, 30, 35 e 40 °C), umidade (0 e 6 h em câmara úmida), concentração de inóculo de Acidovorax avenae subsp. citrulli (0; 3,4 x 10¹; 3,4 x 10²; 3,4 x 10³; 3,4 x 10(4); 3,4 x 10(5); 3,4 x 10(6) e 3,4 x 10(7) UFC.ml-1) e idade do fruto (40, 50, 60 e 70 dias) na severidade da mancha-aquosa em frutos de melão (Cucumis melo) do tipo Amarelo. Os frutos foram inoculados pelo método de injeção subepidérmica determinando-se: período de incubação, diâmetro da lesão … Show more

“…Similarly, Bacillius sp. strain BA-46 controlled the bacterial wilt disease by 21.13% in tomato under greenhouse conditions (Silveira et al, 1995). T. harzianum, isolated from Sikkim was found effective in controlling ginger wilt caused by R. solanacearum (Raj an et al, 2002).…”

“…Soil is an irregular, diverse and structured environment where bacteria could face stresses caused by restrictions in nutrient availability or fluctuations in time of physical and chemical factors (ELSAS et al, 2000). The temperature range around 30 to 35 ºC is considered optimum for the development of bacterial fruit blotch in melons (SILVEIRA et al 2004) and the growth of A. citrulli on a culture medium. However, a higher RERP of the bacterium were generally determined at temperatures between 30 and 35 ºC as well as a lower temperature of 10 ºC.…”
