1. Satsuma mandarins grafted onto Swingle citrumelo for early season harvest in subtropical conditions in Brazil
ABSTRACT Although Brazil is the sixth producer of mandarins in the world, fresh fruit exports are neglectable, and few cultivars are available for the domestic market. Main harvest season comprises May to November, with Ponkan mandarin and Murcott tangor representing more than 70% of the production. Therefore, there is a need for alternative early season, se

2. Estudo da variação do perfil químico de laranja pêra e tangor Murcott após a inoculação do fungo Alternaria alternata
This paper describes the study of variation in the chemical profile of citrus after inoculation of the fungus Alternaria alternata, who causes the disease known as alternaria brown spot (ABS), which is one of the most serious diseases in orchards of tangerines, causing major damage to the Brazilian citrus. For this, A. alternate was inoculated in sweet orang

3. Resistance and susceptibility of mandarins and their hybrids to Alternaria alternata
Caused by Alternaria alternata, Alternaria brown spot (ABS) is a major fungal disease of mandarins in Brazil, causing serious losses in commercial orchards of Ponkan tangerine (Citrus reticulata Blanco) and Murcott tangor [C. sinensis (L.) Osbeck × C. reticulata Blanco]. The response of 31 accessions/genotypes of mandarins and their hybrids to A. alternata,

5. Aspectos químicos envolvidos nas interações de Citrus com fitopatógenos / CHEMICAL ASPECTS RELATED TO THE INTERACTION BETWEEN Citrus PLANTS AND PHYTOPATOGENIC FUNGI
This present thesis describes the development of analytical methodologies involving the HPLC-PDA-MS/MS coupling to verify the production of both polar and non-polar metabolites in orange trees produced by grafting Citrus sinensis onto Citrus limonea. By the use of such kind of method, it was possible to verify the production of both polymethoxy and glycosyl

6. Resistence to leprosis and alternaria brown spot in citrus / Resistencia a leprose e a mancha marrom de alternaria em citros : caracterização de hibridos, herança, mapeamento genetico e expressão genica
A leprose dos citros e a mancha marrom de Alternária são importantes doenças da citricultura. O conhecimento dos mecanismos genéticos envolvidos nas resistências apresentadas por algumas espécies e híbridos de citros a estas doenças é de fundamental importância para o desenvolvimento de estratégias para o melhoramento genético visando à utiliza�

7. Fungi Isolated from Tobacco Leaves and Brown-Spot Lesions Before and After Flue-Curing1
Discs of tissue excised from ripe nonflue-cured and flue-cured tobacco leaves, harvested on six dates and cultured on three selective media, yielded 21 and 24 genera of fungi, respectively. Of 5,094 fungi isolated from 3,240 pieces of nonfluecured leaf tissue, 89.5% comprised five genera, Alternaria, Cladosporium, Epicoccum, Trichoderma, and Nigrospora. Of 2

8. Mouse Toxicity of Fungi of Tobacco1
A bioassay for fungal toxins based on the intraperitoneal injection of test materials into mice was used to screen 976 cultures isolated from tobacco and grown in a high-protein baby cereal and also to determine whether samples of tobacco damaged by fungi are more toxic than samples of apparently sound tobacco. Of 236 fungal isolates from noncured tobacco, 7
