Reação de genótipos de maracujazeiro-amarelo ao Colletotrichum gloeosporioides Reaction of sour passionfruit genotypes to Colletotrichum gloeosporioides

Abstract

O presente trabalho foi desenvolvido em casa de vegetação, na Estação Biológica da Universidade de Brasília, com objetivo de avaliar genótipos de maracujazeiro-amarelo frente ao fungo C. gloeosporioides, agente causal da antracnose. Para inoculação dos genótipos, utilizou-se uma suspensão contendo 5x10(6) esporos/mL do patógeno, depositados sobre ferimentos preestabelecidos com auxílio de escova de aço de cerdas finas. A primeira avaliação foi realizada 20 dias após a inoculação, e as demais, a intervalos de 7 dias, encerrando-se na sétima avaliação, aos 62 dias. Determinaram-se a incidência e a severidade da antracnose, com auxílio de uma escala graduada de notas, onde 1 = ausência de sintomas e 7 = desfolha. Consideraram-se as plantas como: Resistentes (R), com notas médias 2 e 3 e 4. No geral, dois genótipos foram classificadas como Moderadamente Resistentes; oito, como Suscetíveis e 62, como Altamente Suscetíveis.The present work was carried out in order to evaluate the resistance of passion fruit genotypes to C. gloeosporioides, the agent of anthracnose. C. gloeosporioides was inoculated in the lineages of passion fruit plants at a concentration of 5x10(6) spores on wounds pre-established by abrasion with a fine steel brush. The first evaluation was carried out 20 days after the inoculation and the others in intervals of seven days, ending in the seventh evaluation 62 days after the inoculation. To evaluate the degree of incidence and severity of anthracnose, a grade scale was established, where 1 = absence of symptoms and 7 = leaf loss. Average grades 2 and 3 and = Highly Susceptible (HS). In general, two genotypes were classified as Moderately Resistant; eight as Susceptible and sixty-two were highly Susceptible.
