4. Sunki mandarin and Swingle citrumelo as rootstocks for rain-fed cultivation of late-season sweet orange selections in northern São Paulo state, Brazil
ABSTRACT In Brazilian regions affected by the citrus sudden death disease, sweet orange cultivation depends on the use of resistant rootstocks. Rangpur lime was mainly replaced by Swingle citrumelo and Sunki mandarin rootstocks, more drought-sensitive ones. The diversification of scion selections is also desirable aiming at the increasing demand for not from

5. Agronomic performance of Pera and related sweet orange accessions naturally infected with Citrus tristeza virus in northern Paraná State, Brazil
Despite of the susceptibility to the Citrus tristeza virus (CTV), Pera sweet orange is the most important citrus cultivar in Brazil. The objective of this study was to evaluate the CTV aggressiveness and the relationship with the agronomic performance of 24 accessions of Pera and related sweet oranges. Accessions belonging to the Citrus Germplasm Collection

6. Comparison of Citrus tristeza virus (CTV) isolates by RFLP analysis of the coat protein nucleotide sequences and by the severity of the symptoms
Plants of Pera sweet orange on Rangpur lime rootstocks, from orchards of the northwest and north of Paraná state, Brazil, were evaluated for severity of symptoms and genetic diversity of Citrus tristeza virus. The severity of symptoms was evaluated by the development of tree, fruit size and stem pitting symptoms. Isolates that infect these plants were compa

7. DRIS norms for 'Valencia' sweet orange on three rootstocks.
Diagnosis and Recommendation Integrated System (DRIS) applies nutrient ratios instead of the isolated concentration values of each nutrient in interpretation of tissue analysis. The objectives of this research were to establish adequate DRIS norms for 'Valencia' sweet orange irrigated commercial groves budded on three rootstocks and correlate indexes of nutr

10. Spatio-temporal dynamics of populations of the citrus leprosis pathossystem under natural epidemic conditions / Dinâmica espaço-temporal de populações do patossistema leprose dos citros em condições naturais de epidemia
Citrus leprosis, caused by Citrus leprosis virus (CiLV), is a disease endemic to the producing regions of the state of São Paulo, where it has a heavy impact on production. The virus is transmitted exclusively by the Brevipalpus phoenicis mite and disease control measures aim to reduce the vector population mainly by acaricide applications. Although the dis

11. Analise da expressão diferencial de genes de citros em resposta a infecção por Xanthomonas axonopodis pv. citri / Differential gene expression of citrus in response to infection by Xanthomonas axonopodis pv. citri
The citrus canker disease, caused by Xanthomonas axonopodis pv. citri (Xac), has emerged as one of the major threats to the Brazilian citriculture because it affects all commercial citrus varieties, decreases the production and quality of the fruits and can spread rapidly in the citrus growing areas. The symptoms include canker lesions, leading to abscission

12. Dinâmica populacional de afídeos (Hemiptera: Aphididae) em árvores cítricas no município de Nova Granada - SP / Population dynamics of aphids (Hemiptera: Aphididae) on citrus trees in Nova Granada County, São Paulo State, Brazil
Because aphids are possibly involved in the spread of viruses associated with a new and destructive disease, citrus sudden death (CSD), it is important to know their population dynamics in order to understand disease epidemiology. The goal of this research was to determine the main aphid species that colonize citrus groves [Citrus sinensis (L.) Osbeck] in CS
