1. Effect of water activity and storage of tahini on the viability of stressed Salmonella serovars
Abstract Tahini (sesame seed paste) is a low water activity product that has been involved in several salmonellosis outbreaks. The objectives of the study were to examine over a year the impact of aw and storage temperature of tahini on the viability of Salmonella serovars previously stressed by drying or heat exposure. Tahini samples adjusted to aw values o

2. Physiological Quality of Carioca Bean Seeds Submitted to the Application of Desiccant Herbicides in Two Periods
RESUMO: A dessecação da cultura do feijão destinado à produção de sementes, com a utilização de herbicidas, é uma alternativa de manejo, pois permite a colheita quando as sementes apresentam elevado vigor, germinação e massa seca, porém essa técnica pode ocasionar prejuízos às sementes. Objetivou-se com este trabalho avaliar a qualidade fisiol

3. Pre-Harvest Desiccation in Productivity and Physiological Quality of Cowpea Seeds
RESUMO: A dessecação pré-colheita é uma estratégia importante no sentido de antecipar a colheita, evitando que a semente fique no campo em condições climáticas desfavoráveis. No entanto, pouco se sabe sobre o uso de dessecantes e as épocas de aplicação destes na cultura do feijão-caupi (Vigna unguiculata). Objetivou-se neste trabalho avaliar efe

4. Physiological and biochemical changes during desiccation tolerance loss in millet (Pennisetum glaucum L.) seeds
ABSTRACT. The aim of this study was to evaluate the physiological and biochemical changes related to desiccation tolerance loss in millet seeds. The studied points of the germination process were determined according to the seed imbibition curve of the millet hybrid ADRF6010: control (0h), 3h of imbibition, 1 and 3 mm radicle. The seeds were dried on silica

5. Drying and reduction in sensitivity to desiccation of seeds of Alibertia edulis: the influence of fruit ripening stage
ABSTRACT The intense environmental degradation in tropical regions suitable for agriculture has decreased native forest populations of plants with important fruits and medicinal properties. Alibertia edulis is a native tree from the Brazilian Cerrado. Knowledge about the effects of drying and storage on the physiological behavior of its seeds may aid in its

6. Disentangling plant establishment in sandy coastal systems: biotic and abiotic factors that determine Allagoptera arenaria (Arecaceae) germination
ABSTRACT Germination rate and establishment success of plants in harsh environments depend on the ability of seeds to withstand unfavorable environmental conditions and avoid predators. Brazilian coastal plains, known as restinga, are subject to environmental factors that seriously limit plant establishment and survival (e.g. salinity, desiccation, oligotrop

7. Yield, specific mass and coloration of azuki seeds after desiccation and storage
ABSTRACT Selection and dosage of desiccating herbicides may bring benefits to bean harvesting and its seed quality. This study aimed to assess yield, apparent specific mass and coloration of azuki bean seeds after pre-harvesting desiccation with different herbicides and doses and subsequent storing. In a first trial, we tested paraquat 400 (g ai ha-1), ammon

8. Campomanesia adamantium (Cambess.) O. Berg seed desiccation: influence on vigor and nucleic acids
O objetivo desse trabalho foi avaliar a sensibilidade à dessecação em sementes de Campomanesia adamantium, por meio de secagem em sílica gel ativada (rápida) e em condições de laboratório (lenta). Para avaliar a sensibilidade à dessecação das sementes, realizou-se a secagem com sílica gel e secagem em condições de laboratório (25 °C) visando

10. Desiccation tolerance in seeds of Annona emarginata (Schldtl.) H. Rainer and action of plant growth regulators on germination
Annona emarginata (Schldtl.) H. Rainer ("araticum-de-terra-fria") is used as a rootstock for several species of Annonaceae. It is suggested that these seeds should be sown immediately after extraction and, therefore, they could be intolerant to desiccation. There are several mechanisms involved with desiccation tolerance. Soluble sugars, for example, can acc

11. Épocas de la aplicación de desecantes en el cultivo de la soja: tenor de agua y productividad
The herbicides glyphosate and paraquat have been used by Brazilian soybean producers to obtain crop desiccation and to anticipate and uniformity at harvest. However, improper use of herbicides can to occasion problems in agronomic and physiologic characteristics of crop. This study aimed to evaluate the use of the glyphosate and paraquat herbicides as a desi

12. Banco de sementes e sistemas de renovação no pasto de capim-braquiária com integração de culturas agrícolas / Seed bank in renewal of pasture signal grass with crop livestock integration
The experiment was conducted to evaluate the renewal of pasture of Brachiaria decumbens with integration of crops in cropping systems "planting" direct and conventional. The experiment was conducted in pastures of Brachiaria decumbens Stapf. Located on the campus of University Federal of Viçosa, Viçosa, MG. The experiment consisted of five "systems" of gra
