a partir del sexto día de la inoculación y el desarrollo de la enfermedad se explicó por un modelo de regresión lineal simple (Y = 1.123 + 0.1133X). No se detectó la formación de apresorios pero sí la síntesis de una capa mucilaginosa asociada con los tubos germinativos. El proceso infectivo del hongo se manifestó con la penetración de las hifas intra e inter-celularmente y con la producción de acérvulos a partir de los 12 días después de la inoculación. Los síntomas de la antracnosis se asociaron con la degradación de polifenoles, plasmólisis, necrosis y desintegración celular Palabras Clave: Persea americana L., antracnosis, patogenicidad, patogénesis. ANALYSIS OF Colletotrichum gloeosporioides (Penz.) Penz. & Sacc. INFECTION OF AVOCADO FRUITSABSTRACT -The pathogenesis of Colletotrichum gloeosporioides (Penz.) Penz. & Sacc. from the state of Michoacán, México was characterized in avocado (Persea americana L.) fruits cv. 'Hass'. The fungus caused typical disease symptoms of 'anthracnose' ten days after inoculation. Fungal infection rate was significantly different (p≤0.05) between treatments since the sixth day after inoculation and the disease development was explained by one simple linear regression model (Y = 1.123 + 0.1133X). No appresoria were found but one mucilagous layer associated to germ tubes was detected. Fungal infective process started with intra and intercellular penetration by hyphae and after, acervuli were produced twelve days after inoculation. Anthracnose symptoms were associated with poly-phenol degradation, plasmolysis, necrosis and cell disintegration
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
