ABSTRACT Occurrence of Fusarium spp. is one of the problems, most limiting to growth of seedlings, in nurseries. This pathogen can be transmitted via seeds and causes damages to the seedlings during pre- and post-emergence stages. The present study aimed to identify Fusarium spp. at the species level based on morphological and molecular characteristics and to verify the pathogenicity of these isolates in seeds lots of Pinus elliottii and P. taeda. For this, we used two Fusarium isolates and five lots of Pinus spp. seeds. Morphological characterization was performed based on a key, specific to Fusarium spp. identification, whereas, molecular identification was carried out by amplification and sequencing of the regions from internal transcribed spacer (ITS)... |
