Resumo
Com o objetivo de avaliar a reação de clones de umezeiro (Prunus mume Sieb. et Zucc.) e cultivares de pessegueiro [Prunus persica (L.) Batsch] ao nematóide anelado Mesocriconema xenoplax (Raski) Loof & de Grise, realizou-se o presente estudo em casa de vegetação do Departamento de Fitossanidade da FCAV/UNESP, Câmpus de Jaboticabal-SP. As plantas foram mantidas em vasos de cerâmica com 6 litros de capacidade, contendo uma mistura de solo e areia (1:1, v/v), previamente autoclavada a 121°C e 1kgf.cm-2 por 2 horas. Cada planta foi inoculada com 10mL de uma suspensão de 200 M. xenoplax por mL. Com os resultados obtidos, após 105 dias da inoculação, pode-se concluir que os Clones 05; 10 e 15 de umezeiro e as cultivares Okinawa e Aurora-1 de pessegueiro são suscetíveis a M. xenoplax. A cultivar Aurora-1 apresentou maior Fator de Reprodução (93,06).
With the objective of evaluating the reaction of mume clones (Prunus mume Sieb. et Zucc.) and peach tree cultivars [Prunus persica (L.) Batsch] to ring nematode Mesocriconema xenoplax (Raski) Loof & de Grise, was conducted the present study at a greenhouse, belonging to the Phytosanity Department of Faculdade de Ciências Agrárias e Veterinárias (FCAV/UNESP), Jaboticabal Campus, São Paulo State, Brazil. The plants were maintained in ceramic boxes with 6 liters of capacity, contends a soil-sand mixture (1:1, v/v), previously autoclaved at 121°C and 1kgf.cm-2 for 2 hours. Each plant was inoculated with a 10mL suspension of 200 M. xenoplax/mL. With the results, after 105 days of inoculation, was verified that mume Clones 05, 10 and 15 and 'Okinawa' and 'Aurora-1' peach tree cultivars are susceptible to M. xenoplax. The cultivar 'Aurora-1' presented larger reproduction factor (93,06).
