| O objetivo deste trabalho é avaliar a resistência de 15 variedades de mangueira em relação a dois isolados do fungo Ceratocystis fimbriata Ell. & Halst.: o IAC FITO 4905, muito patogênico ao cultivar Jasmim, e o IAC FITO 334-1, não patogênico ao 'Jasmim'. As inoculações foram feitas no campo, em ramos a 40 cm do ápice, utilizando-se plantas com oito anos de idade, com delineamento em blocos completos ao acaso e parcelas subdivididas. Os cultivares São Quirino, Irwin, Edwards e Van Dyke foram resistentes aos dois isolados, e Glenn, Joe Welch, Zill e Haden suscetíveis. 'IAC 100 Bourbon' mostrou resistência moderada aos dois isolados e o 'Kent' comportou-se como o 'Jasmim' resistente ao isolado FITO 334-1 e suscetível ao IAC FITO 4905, podendo ser... |

| ABSTRACT Mango wilt, caused by Ceratocystis fimbriata, is one of the most important diseases affecting mango yield worldwide. Salt stress can affect host defense responses against pathogens infection. The aim of this study was to evaluate the development of mango wilt in 2 mango cultivars submitted to salt stress. Mango plants from cultivars Tommy Atkins and Ubá, considered to be moderately resistant and resistant to mango wilt, respectively, were grown in plastic pots which contained 20 kg of washed sand and daily irrigated with 3 L of a modified Hoagland solution during 40 days before being submitted to salinization. For this process of salinization, the plants received nutrient solution containing 0, 30, 60, and 90 mmol∙L–1 of sodium chloride (NaCl)... |

| ABSTRACT Mango wilt, caused by Ceratocystis fimbriata, is one of the most important diseases affecting mango yields in Brazil. Information regarding the biochemical mechanisms involved in mango resistance against C. fimbriata is absent in the literature. Thus, the present study determined and quantified alkaloids and phenolics in the stem tissue of mango plants from Palmer (susceptible) and Ubá (resistant) cultivars. Furthermore, it was examined the effect of these secondary metabolites against C. fimbriata growth in vitro. The high-performance liquid chromatography revealed that the concentration of two alkaloids (theobromine and 7-methylxanthine) and six phenolic compounds (caffeic acid, p-coumaric acid, gallic acid, protocatechuic acid, catechin and... |

| Solid state fermentations were carried out to test the efficacy of Ceratocystis fimbriata to grow on different agro-industrial substrates and aroma production. Seven media were prepared using cassava bagasse, apple pomace, amaranth and soya bean. All the media supported fungal growth. While amaranth medium produced pineapple aroma, media containing cassava bagasse, apple pomace and soya bean produced a strong fruity aroma. The aroma production was growth dependent and the maximum aroma intensity was detected a few hours before or after the maximum respirometric activity. Sixteen compounds were separated by gas cromatography of the components present in the headspace and fifteen of them were identified as acid (1), alcohols (6), aldehyde (1), ketones (2)... |
