Abstract: Parametros físico-químicos foram usados para avaliar a qualidade do palmito de pupunha in natura, em programa de melhoramento genético para qualidade do material produzido. Foram monitorados o pH, a acidez titulável (ATT) e os sólidos solúveis (SS) do palmito in natura, durante o armazenamento sob refrigera o, das duas mais relevantes popula es de pupunha cultivadas no Brasil. Foram realizadas análises microbiológicas e detectadas diferen as significativas entre as popula es de Benjamin Constant (Brasil) e Yurimáguas (Peru) para ATT e SS, mas n o para pH, o que evidencia que os dois primeiros s o adequados para diferenciar popula es de pupunha. Embora os níveis de pH tenham sido pouco ácidos (5,6 a 6,2), as análises microbiológicas mostraram que o palmito in natura permaneceu, durante o armazenamento refrigerado, dentro dos padr es microbiológicos para vegetais minimamente processados. As varia es do pH, acidez titulável e sólidos solúveis durante o armazenamento foram, em geral, pequenas. doi: 10.4336/2010.pfb.30.63.261 Physic-chemical parameters were used to evaluate the quality of fresh palm hearts of palm in the breeding program for quality of material produced. We monitored the pH, acidity (TA) and soluble solids (SS) of palm fresh during storage under refrigeration of the two most important populations of peach palm cultivated in Brazil. Were analyzed for microbiological and significant differences between the populations of Benjamin Constant (Brazil) and Yurimaguas (Peru) to ATT and SS, but not for pH, which shows that the first two are suitable to differentiate populations of peach palm. Although levels were slightly acid pH (5.6 to 6.2), Microbiological analysis showed that the palm remained fresh during storage with microbiological standards for minimally processed vegetables. Variations in pH, acidity and soluble solids during storage were generally small. doi: 10.4336/2010.pfb.30.63.261

Abstract: lettuce is considered the main leafy vegetable crop in brazil. in recent decades, many changes occurred towards the varietal types as well as in the preference for pelleted seeds. until mid 90 decade, the dominant varieties of looseleaf lettuce were the type 'white boston' and 'regina'. later, there was a change toward the grand rapids type which represents the main varietal segment grown in brazil. the non-head grand rapids type with its earliness performed better adaptation for hot and high rainfall summer season. brazilian preference for the grand rapids type is a unique event in the world market of lettuce. crisp head lettuce had increased its preference, but there are many limitations to grow this type outdoors in our rainy hot summer. thicker leaves of iceberg have a better flavor, crispness and long shelf live under refrigeration for its post-harvest management. crispness is an important and mandatory quality for the fresh cut market which is a growing tendency. considerations on breeding focus to get tropical-adapted varieties with crispness and resistance to specific brazilian diseases which are limiting to lettuce are discussed.

Abstract: INTRODU O: Fez-se uma análise da incidência de dengue na cidade de S o José do Rio Preto, SP, durante epidemia (sorotipo I) ocorrida no primeiro semestre de 1995, em fun o de áreas geográficas (unidades ambientais urbanas) definidas através de variáveis econ mico-sociais. MATERIAL E MéTODO: Utilizou-se método epidemiológico do tipo "estudo ecológico". Para o cálculo do coeficiente de incidência (CI) foram considerados os casos de dengue confirmados e notificados entre janeiro e julho de 1995. As unidades ambientais foram definidas a partir de variáveis socioecon micas, tendo como base o setor censitário do IBGE, através de análise de agrupamento. Calculou-se o coeficiente de correla o linear entre o CI e variáveis ambientais. RESULTADOS E CONCLUS ES: Com base na distribui o de renda e no nível educacional foram identificadas três unidades ambientais. O CI de dengue variou de forma inversa com o padr o socioecon mico da unidade. Discutiu-se o papel da densidade populacional e dos servi os de saneamento ambiental, no nível de incidência. Ressaltou-se a importancia do estudo para o controle da dengue.
