| The effects of Coda Radimax (CR), Coda Humus-PK (CH) and Coda Vit (CV) on the induction of resistance for Meloidogyne incognita in sugarcane (Saccharum sp.) varieties (RB92579, RB863129, RB867515) through nematode reproduction, plant development and root anatomy analysis, emphasizing the differences of the lignin deposition, and cortex-vascular cylinder proportions were investigated. In 90 days after inoculation with eggs of M. incognita, CR reduced the number of eggs per root system in all the sugarcane varieties; CH and CV reduced eggs density in RB867515; CR increased stalk number in RB92579 and fresh weight of shoots in RB863129 and RB92579; CH increased plant height in RB92579 and fresh weight of shoots in RB92579 and RB867515, CV affected fresh weigh... |

| The aim of the present work was to analyze the molecular methods in the differentiation of Colletotrichum gloeosporioides isolates obtained from the cashew and mango trees. The different molecular taxonomic methods used proved to be efficient regarding intraspecific characterization. Similarly, molecular methods also proved to be efficient in differentiation of the C. gloeosporioides isolates in relation to host specificity. In the analysis of the ITS sequence of the ribosomal DNA, all the isolates amplified with the CgInt and ITS4 primers, confirming that they pertained to C. gloeosporioides. The results from this study suggested that methods based on the pathogenicity, isozyme analysis and RAPD were effective in differentiating C. gloeosporioides... |

| A antracnose afeta a qualidade de inflorescências de plantas ornamentais tropicais, e a espécie fúngica Colletotrichum gloeosporioides tem sido relacionada a essa doença apenas por análises morfológicas. Por isso, o presente trabalho teve como objetivos identificar isolados de Colletotrichum coletados em plantas de antúrio (Anthurium andraeanum), bastão do imperador (Etlingera elatior) e helicônia (Heliconia spp.), por meio de caracteres morfológicos e reação em cadeia da polimerase (PCR), e avaliar a variabilidade genética por meio de oligonucleotídeos arbitrários (AP-PCR). Pelas características morfológicas de tamanho de conídio e de apressório, todos os isolados foram identificados como C. gloeosporioides. Um fragmento de 450pb específico para C.... |
