| Environmental degradation caused by the excessive use of pesticides has motivated studies aimed at the discovery of new formulations for pest control. The bioassays carried out under laboratory conditions for the present study involved the germination and seedling growth of Lactuca sativa cv. Grand Rapids and Allium cepa cv. Baia Periforme treated with lecanoric acid or one of seven esters obtained from the alcoholysis of the acid. Each substance was tested at concentrations of 10-3, 10-5, 10-7 M, and 10-9 M. The results revealed that, except for lecanoric acid and methyl orsellinate, all other compounds exhibited significant differences in their action when compared with the controls. Also, A. cepa was more sensitive to the compounds assayed, at the... |

| Abstract Passiflora cincinnata is a species of wild passion fruit whose fruit has potential for use by the food industry. In this context, an anatomical study of the pericarp may help in understanding the changes which occur during the postharvest period. The objective of this work was to anatomically characterize the P. cincinnata pericarp, focusing on the structural changes which occur during refrigerated storage. The selected fruits were kept in net-like packaging at 5°C and evaluated every 15 days for a period of 90 days. Pericarp samples were hand cut on these dates for structural description and to detect starch, phenolic compounds, alkaloids, polysaccharides, proteins, lipids and lignin through histochemical tests. Other samples were analyzed by... |

| O objetivo deste trabalho foi avaliar a influência do inibidor da síntese de etileno aminoetoxivinilglicina (AVG) aplicado na forma de solução de condicionamento e pulverização sobre a abscisão e longevidade de inflorescências de Epidendrum ibaguense Kunth. As hastes foram colhidas e imediatamente condicionadas em solução com 0, 0,5, 1, 1,5 e 2 mM de AVG por 6, 12, 18 e 24 horas. Os mesmos tratamentos foram aplicados na forma de pulverização até o molhamento completo da inflorescência. O experimento foi conduzido em um esquema fatorial entre tempo de aplicação e doses de AVG, mais doses de AVG aplicadas em pulverização nas flores, e o delineamento foi em blocos ao acaso, com cinco repetições, com três hastes por unidade experimental. Independentemente do... |

| This work had the goal to evaluate the influence of temperature and dry storage on the postharvest longevity of Epidendrum ibaguense flowers previously treated with silver thiosulfate (STS). The flowers were harvested and pulsed for 30 minutes with 2 mM STS. Then both, the STS treated and untreated flowers were packed in perforated low density polyethylene bags, packed in cardboard boxes and stored at 5 and 10°C, where they remained for four and eight days. After this period, the flowers were kept in vase with distilled water at 25ºC, and analyzed at every 24 h. The experiment was arranged in a complete random design 2 x 2 x 2 factorial scheme, with four replicates, containing four inflorescences each, except for the determination of transpiration and... |
