Purificação parcial de inibidores de tripsina de sementes de Caesalpinia ferrea e Swartzia polyphylla e o efeito dos extratos protéicos sobre fungos fitopatogênicos
TLDR
The results suggest that these tropical tree species are promising for the exploration of natural fungicides, since the extracts reduced mycelial growth and sporulation of C. guaranicola, C. cassiicola and F. oxysporum and S. rolfsii.
Histologia da interação Colletotrichum guaranicola e Paullinia cupana var. sorbilis em clones resistente e suscetível
The pre-penetration and infection processes of Colletotrichum guaranicola on resistant and susceptible clones of Paullinia cupana var. sorbilis were studied by light microscopy. The percentage of
DIVERSIDADE E ESTRUTURA GENÉTICA DE Senna reticulata
Senna reticulata (Willd.) H. S. Irwin & Barneby e uma planta arborea pioneira em areas abertas de planicies aluviais da Amazonia e frequentemente usada como planta medicinal. Devido a escassez de
Localização de peróxido de hidrogênio durante a resposta de defesa de tomateiro contra Stemphylium solani
TLDR
Two tomato cultivars were studied due to their reaction with cerium perhydroxide, verifying H2O2 produced in tomato plants boyh resistant and susceptible to Stemphylium solani.
Caracterização Morfológica de Acessos de Pimentas do Amazonas
TLDR
O presente trabalho teve como objetivo caracterizar morfologicamente e estimar a diversidade genetica de 40 acessos de pimentas coletados no Amazonas pertencentes a colecao de germoplasma da Universidade Federal do Amazonas.
Variabilidade de isolados de Corynespora cassiicola (Berk. & Curt.) Wei procedentes do Amazonas, em meios de cultura
TLDR
The highest mycelial growth rate occurred in CA medium and the highest sporulation in the media PDA and PSA for isolates from tomato and cucumber, and the aspect of colonies varied in color between isolate from the same host and between isolate from different hosts for all culture media.
Variabilidade genética de Colletotrichum guaranicola usando marcadores AFLP
TLDR
The genetic variability of twenty Colletotrichum guaranicola (Albuq.) isolates from different fields of guarana in Amazonas, was studied using molecular AFLP markers, confirming that the isolates belongs to the same species.
Histologia da interação Stemphylium solani e tomateiro
TLDR
The histological studies showed that the initial infection events were similar in resistant and susceptible plants, and no quantitative differences were found in the pre-penetration conidial events onresistant and susceptible tomatoes, indicating that resistance results from post- penetration responses.
