Estudio preliminar sobre métodos de detección de Microdochium oryzae en semillas de arroz

Abstract: RESUMENEn ensayos conducidos en laboratorio, fueron evaluados cuatro métodos (Papel de filtro, Agar papa glucosado, Agar poroto y Agar extracto de malta), considerándose su eficiencia y sensibilidad para detectar Microdochium oryzae en semillas de arroz, variedad Fortuna. Los datos obtenidos fueron sometidos al análisis de varianza y las medias comparadas por con el test de Tukey. Entre los métodos probados, las mayores incidencias de M oryzae fueron detectadas en las semillas sembradas en medio conteniendo ag… Show more

“…Gutierrez et al, (2007) detected the presence of the sexual stage of the fungus, Monographella albescens, during the crop cycle 2004/2005 and 2005/2006 in Corrientes, province of Argentina. Gutierrez et al, (2009) mentioned that the fungus is associated with rice grains integrating the causal complex of spotting rice husks at Northern Argentina.…”

“…Dichos valores se aproximarían a lo observado en semilla de otros países de la región, cuyos autores utilizaron el método del papel de filtro o blotter test. En el año 2001, en Brasil determinaron un valor de 18% en semillas de arroz de la región de Rio Grande do Sul (RS) (14) . Posteriormente, en 2007 autores brasileños también reportaron niveles de 4,9% y 24,6 % de incidencia respectivamente en RS y Sao Paulo (15,16) .…”

“…MALAVOLTA (2007), using filter paper method detected an average incidence of M. oryzae of 24.6 and 29.8%, respectively in 2003 and 2004, in rice genotype seeds in the of São Paulo (SP) state. PSA medium is more efficient in detecting M. albescens when compared to the filter paper method (GUTIÉRREZ et al 2009). Analyzing genotypes, a higher incidence was observed in SCS116 Satoru (72.3% in 2015/16 crop) and lower in SCS122 Miura (43.1% in 2016/17 crop).…”
