Plants of lettuce cv. Salad Regina that showed symptoms of a wilt disease were observed in commercial fields in the Marechal Floriano and Caxixe production regions in the highlands of Espirito Santo State (ES), Brazil. Wilted plants were first observed during the 2000 cropping season (June to September) when temperatures were between 26 and 34°C. Outbreaks of wilt in the Caxixe Region also occurred in the last 2 years on cultivars of the Lisa type. Symptoms were observed on seedlings and adult plants. Affected plants appeared wilted, showed red-to-brown discoloration of vascular tissues, were stunted, and developed yellow leaves that had brown or black streaks in the vascular system. The vascular streaks in the yellow leaves were continuous from the red-brown vascular discoloration in the crown. A Fusarium sp. was consistently and readily isolated by plating surface-sterilized (with NaOCl) root and crown tissue segments from symptomatic plants onto lactic-acid-amended potato dextrose agar and a Fusarium-selective medium (4). To complete Koch's postulates, a single hyphal tip of the isolated fungi was transferred to carnation leaf agar. Micro- and macroconidia formed abundantly within 8 days and matched the description of Fusarium oxysporum Schlechtend. Fr. Two- to three-week-old lettuce seedlings of each of six cultivars (Monalisa AG-819, Grand Rapids Nacional, Regina, Carolina AG-576, Vitória, and Grandes Lagos), representing the range of lettuce genetic diversity typically planted in Espirito Santo, were inoculated with the isolated fungus by dipping the roots of each plant in a spore suspension (1 × 105 CFU/ml) or planting the seedlings in a steam-sterilized soil infested with the fungus at 1 × 105 conidia/ml potting medium. Ten inoculated seedlings of each cultivar were arranged in a completely randomized design and placed in a greenhouse (26 ± 2°C) to allow development of the infectious agent. Ten noninoculated plants of each cultivar served as control treatments. Wilt symptoms developed on all inoculated plants 20 to 30 days after inoculation, and infected plants showed the same symptoms as observed on the original plants from which the pathogen was isolated. Noninoculated plants remained symptomless. F. oxysporum was consistently reisolated from the inoculated seedlings. The pathogenicity test was conducted twice. A wilt of lettuce attributed to F. oxysporum f. sp. lactucae was previously reported in Japan (3) and later in the United States where the disease was attributed to F. oxysporum f. sp. lactucum (2). In 2002, a lettuce wilt caused by F. oxysporum f. sp. lactucae was reported in Italy (1). Studies are being carried out to determine the formae speciales of these Brazilian lettuce isolates of F. oxysporum. To our knowledge, this is the first report of F. oxysporum on cultivated lettuce in Brazil. MenosPlants of lettuce cv.

O presente trabalho teve como objetivo avaliar o 'Tipo do Café Conilon' em função do tempo entre a colheita e o início da secagem e do armazenamento. O experimento foi conduzido na Fazenda Experimental de Marilândia, utilizando frutos do c\one 153 de café conilon. Parte do café foi levada para o início do processamento imediatamente após a colheita e outras duas partes permaneceram ensacadas, respectivamente, por 48 horas e 96 horas. Nas três partes foram obtidos café natural e café cereja descascado. Após a secagem os cafés foram armazenados por um ano. O café cereja descascado apresenta menor percentagem de grãos ardidos e números de defeitos que o café natural, independente do tempo que o café ficou amontoado e do período de armazenamento.Verificou-se tendência do aumento da percentagem de grãos ardidos e de defeitos durante o armazenamento e para os cafés que permaneceram amontoados na sombra por 48 e 96 horas antes da secagem se iniciar. |
