| In this study, the somatic embryogenesis and regeneration of Cigana Preta plants from shoot apices and immature leaves taken from plants cultivated in vitro were examined. To embryo induction the explants were cultivated in Murashige and Skoog (MS) medium supplemented with 2,4-dichlorophenoxyacetic acid (2,4-D) or 4-amino-3,5,6-trichloropicolinic acid (Picloram) at concentrations of 8.0 and 12 mg L-1. To development of embryos two media cultures with different concentration of BAP (D1 or D2) were evaluated. Embryos in the cotyledonary stage were incubated in germination medium containing MS salts and vitamins, 2.0 µM copper sulfate, 2.4 g L-1 of Phytagel® and 1.77 µM BAP. The highest frequency of calluses and the greatest number of embryos per explant were... |

| ABSTRACT: The cassava market within Distrito Federal (DF) presents potencial for expansion, for that reason, it is fundamental that the propagative material for planting (stem cuttings) presents genetic traits that confer high productivity to the crop, resistance against the main diseases and plagues and culinary qualities that fulfill the demands of the consumer market. In order to select varieties which combine the before mentioned interesting caracteristics for the producers and consumers of DF, we carried out experiments to evaluate table cassava type varieties at Núcleo Rural Jardim, DF (year 1999/2000), at an experimental area of Embrapa Cerrados located in the Municipy of Planaltina, DF (year 1999/2000), at Núcleo Rural Ponte Alta, DF (year... |

| The objectives of this research were to evaluate leaf consumption and the developmental time of the larvae of Erynnyis ello (L., 1758) (Lepidoptera, Sphingidae) reared on cassava, in order to obtain information for the integrated management of this pest. The larvae were reared on excised cassava leaves in Petri dishes and later in gerbox, and kept in chambers at 24 ± 2 ºC and 75 ± 10% RH. The total leaf area consumed by the larva to complete its development was 589.67 cm²; each of the five instars consumed, respectively: 1.89 cm²; 5.74 cm²; 17.48 cm²; 76.66 cm²; and 487.90 cm². The consumption by the first three instars was insignificant, and did not reach 5% altogether; the 4th represented 13%; the 5th presented a consumption significantly higher, about... |
