Microogranisms associated with black point disease

Abstract

Black point disease is characterized by a brown to black discoloration of wheat kernels. The disease can be a problem in regions where are registered heavy rainfall during de early stage of kernels development. Black point disease is associated with many microorganisms, both fungi or bacteria, but those most usually responsible for these symptoms are species of the fungus Alternaria alternate, Cochliobolus sativus, Fusarium graminearum, Aspergillus spp., Penicillium spp. The aims of this study were to identify microorganisms associated with black point disease of wheat. The kernels of twenty-eight winter wheat varieties were analyzed for the purpose of determining the microorganisms associated with the black point.
