Resumo
O presente trabalho teve por objetivos avaliar: 1 - a utilização de aspersão de água e o repouso das suspensões de ovos e juvenis de Meloídogyne spp. pelos períodos de O; 5; 10; 15; 20; 25 e 30 minutos, na eliminação de espumas retidas sobre estes; 2 - a resistência a Me/oidogyne incogníta de 64 genótipos de pimenta Capsícum chínense; cinco da C. annuum; dois da C. baccatum e um da C. frutescens, e de dez cultivares comerciais de pimentão; 3 - a resistência a M. javaníca e a M. mayaguensis dos genótipos resistentes a M. íncognita; 4 - a compatibilidade da enxertia, dos genótipos resistentes a M. íncogníta, com os híbridos de pimentão Rubia R, Margarita e Maximos, nas fases de muda, de crescimento e na produtiva, e 5 - a manutenção da resistência dos porta-enxertos a M. íncogníta, ao final do ciclo da cultura. Os experimentos de aspersão de água e de repouso das suspensões foram conduzidos no Laboratório de Nematologia da UNESP-FCAV, em Jaboticabal-SP, no ano de 2004. Após a trituração das raízes de Capsicum spp., no experimento de aspersão de água, as suspensões foram vertidas na peneira com orifícios de 0,074 mm (200 mesh) sobre a peneira com orifícios de 0,025 mm (500 mesh) e lavadas, sendo as espumas, retidas sobre os ovos e juvenis na peneira de 500 mesh, aspergidas ou não com 50 mL de água, por 20 segundos. No experimento de repouso, após a trituração, as suspensões ficaram em repouso pelos períodos estabelecidos, sendo, na seqüência, vertidas sobre as peneiras e lavadas. Os experimentos de resistência de Capsicum spp. a Meloidogyne spp., de compatibilidade de enxertia e de manutenção da resistência a nematóides de galha, foram conduzidos em casa de vegetação, em Jaboticabal-SP, entre os anos de 2004 e 2005...
The aim of the present work was to study: 1 - the utilization of water sprinkling and letting suspensions of eggs and juveniles of Meloidogyne spp. stand for periods of O; 5; 10; 15; 20; 25 and 30 min, to eliminate foam remaining on them; 2 resistance to Me/oidogyne incognita in 64 pepper genotypes of the species Capsicum chinense, five of C. Annuum, two of C. baccatum and one of C. frutescens, and of ten commercial pepper cultivars; 3 - resistance to M. javanica and M. mayaguensis in genotypes resistant to M. incognita; 4 - compatibility of grafting of genotypes resistant to M. incognita with the bell pepper hybrids Rubia R, Margarita and Maximos, during seedling, growth and productive phases; and 5 - maintenance of resistance of rootstocks to M. incognita at the end of the cultivation cycle. The experiments studying water sprinkling and letting suspensions stand were conducted in the Nematology Laboratory of UNESP-FCAV, at Jaboticabal-SP, during 2004. In nematode application with water sprinkling, the roots of Capsicum spp. were triturated, and the suspensions were poured over a sieve with a pore size of 0.074 mm (200 mesh) on top of a sieve with a pore size of 0.025 mm (500 mesh) and washed; the foam retained on the eggs and juveniles on the 500-mesh was sprinkled or not using 50 mL of water. In the experiment of letting suspensions stand, after trituration the suspensions were allowed to stand for the periods established, after which they were poured over the sieves and washed. The experiments on the resistance of Capsicum spp. to Meloidogyne spp., the compatibility of grafting and the maintenance of resistance to root-knot nematodes were conducted in a greenhouse, at Jaboticabal-SP, between 2004 and 2005. In experiments on resistance of the genotypes to Meloidogyne spp., ten plants were used per genotype, where each plant was considered a repetition... (Complete abstract click electronic access below)
