| Xanthomonas axonopodis pv. citri strains that cause disease in citrus were investigated by pulsed field and plasmid profile analysis. For the first method, genomic DNA was digested by the rare-cutting enzymes Xba I and Vsp I. The strains evaluated were collected in seven different States of Brazil and in Argentina, Bolivia, Paraguay and Uruguay. Genetic variability was found among strains of X. axonopodis pv. citri from different geographical areas Argentina, Bolivia and Uruguay, with similarities varying from 0.62 to 0.83. However, the strains collected in Brazil, despite being from different States, have shown a genetic similarity ranging from 0.83 to 1.00. Cluster analysis showed a relationship between genomic similarity and geographical origin of the... |

| Na implantação dos pomares cítricos, é importante o uso de cultivares adaptadas às condições locais, de forma a assegurar boa produtividade. A laranjeira-'Pera' [Citrus sinensis (L.) Osbeck] é a cultivar mais importante da citricultura brasileira. O objetivo deste trabalho foi avaliar três clones de laranjeira-'Pera' do Banco Ativo de Germoplasma de Citros (BAG-Citros) do Instituto Agronômico do Paraná - IAPAR (acessos I-58 'Pera Vacinada 3', I-59 'Pera Vacinada 4' e I-89 'Pera Bianchi') enxertados sobre o limoeiro-'Cravo' (Citrus limonia Osbeck), nas condições edafoclimáticas de Londrina-PR. As plantas cultivadas no espaçamento 7,0 m x 6,0 m foram conduzidas sem irrigação e avaliadas em relação à produção por planta e às características físico-químicas... |

| Abstract Studies on rootstocks and scions are of major importance for citrus crop production. The goal of this study was to evaluate vegetative growth, yield performance, and fruit quality of ‘Navelina’ sweet orange trees grafted on five different rootstocks in Northern Parana state, Brazil. The experimental design was completely randomized blocks, with six replications, two plants per plot, and five treatments: ‘Rangpur’ lime; ‘Cleopatra’ mandarin, ‘Sunki’ mandarin; ‘Swingle’ citrumelo; and ‘Fepagro C-13’ citrange. Tree vegetative growth, yield performance, and fruit physical-chemical characteristics were analyzed. ‘Sunki’ mandarin provided the largest canopy volume for ‘Navelina’ sweet orange trees, whereas ‘Swingle’ citrumelo, ‘Fepagro C-13’ citrange,... |
