Resumo: | Had been established 15 treatments from the combination of the Magali hybrid chili, grafeted in three rootstocks (AF 3001, AF 8251 and AF 8253, with their respective ungrafted plants) and inoculated with biovars I and III of Ralstonia Solanacearum. Each experimental area had four plants, being used all for evaluations. The used method of graft was of simple crack. Inoculum was constituted of bacterial cells obtained in saline solution from cultures in the logarithmic phase of growth. After the period of evaluations, the plants had been collected for isolation of the pathogen. For the grafted plants were collected three regions: region of the graft and regions above and below of the graft. For ungrafted plants, it was collected the region in the middle of the stem. There had no statistical differences for the height and diameter of fruits among treatments. Treatment AF 8251 - biovar III presented the greater number of commercial fruits for plant. The greater number of no commercial fruits was observed in the control treatment (ungrafted plants of Magali hybrid), to both biovars, and in hybrid AF 8353 - biovar III. Treatments AF 8251 - biovar I, AF 8251 - biovar III and the control treatment showed the best results for total mass of fruits per plant and total productivity. In the interaction rootstocks x regions of the plant, to biovar III, greater value of incidence are found in the region below of the graft in rootstocks AF 3001 |
