| O ensaio foi conduzido numa área experimental da Faculdade de Ciência Agrárias e Veterinárias, Campus de Jaboticabal, da Universidade Estadual Paulista - UNESP, no período de setembro de 1990 a janeiro de 1992. O solo foi classificado como Latossolo roxo, pertencente a serie Jaboticabal. Foram estudadas oito populações naturais de Centrosema pubescens, coletadas na Costa Rica (BRA 014630), em El Salvador (BRA 015024), no Panamá (BRA 014524), na Colômbia (BRA 014494 e 014508) e no Brasil (BRA 003077, 014672 e 014893). Após a germinação as sementes foram repicadas para sacos plásticos contendo solo da área onde foi instalado o ensaio. Nesta fase as mudas permaneceram num ripado por um período de dois meses. O ensaio foi instalado em local definitivo no dia... |

| No Estado do Amazonas, levantamentos realizados no complexo solo-planta-animal indicaram acentuada deficiencia de nutrientes minerais, tais como calcio, cobre, cobalto, zinco, principalmente fosforo, nas pastagens de terra firme dos municipios de Manaus, Itacoatiara e Parintins. Com base nessas deficiencias, foram feitas formulacoes de misturas minerais de modo que bovinos de corte em pastagem de quicuio da Amazonia recebessem quantidades adequadas de fosforo, zinco, cobre, cobalto e iodo. |

| In the present study, genotypic variation of Agrobacterium-mediated transformation of Korean Italian ryegrass has been evaluated. Mature seed-derived calli of seven cultivars were inoculated and co-cultured with Agrobacterium tumefaciens carrying the binary vector pCAMBIA1301, which contains a reporter gene (gus) and a plant selectable marker gene conferring resistance to hygromycin (hpt) in the T-DNA region. The effects of several factors such as callus type and callus age on transformation effectiveness and the expression of the GUS gene were investigated. The highest transformation effectiveness (6.7%) was obtained with the Hwasan 101 cultivar when 9-week-old calli (type-I) were inoculated with Agrobacterium. The overall transformation rates of the... |

| Cratylia argentea (Desv.) Kuntze (Fabaceae) is a drought-tolerant, perennial legume found primarily in Brazil, Bolivia, and Peru. The shrub is well adapted to acid soils and exhibits high productivity and nutritional value, characteristics that would favor its use as a dry season animal forage supplement in semiarid regions. In plant improvement programs, the production of elite hybrids with superior traits is generally achieved by crossing parents that exhibit the highest level of genetic divergence. Therefore, the aim of the present study was to assess genetic diversity among 13 accessions of C. argentea from the same population maintained in the active germplasm bank of Embrapa Meio-Norte using inter-simple sequence repeat (ISSR) markers. Genetic... |

| There is little information known about the response of cup-plant (Silphiumperfoliatum L.), a perennial forage crop introduced to Chile, to differing cultivation practices. A series of studies was conducted to evaluate the adaptation and productivity of cup-plant across a range of plant densities (104,000 - 208,000 plants ha-1), cutting stages (early vegetative to seed formation), and different levels of N (0 - 400 kg N ha-1) and P (0 - 400 kg P2O5 ha-1) fertilization. Field experiments (40°S 73°W) were conducted over a 3-yr period in a subhumid, Mediterranean climate on three distinct andisols that originated from volcanic ash, with pH values of 5.2 to 5.6. The forage dry matter yield, plant components (stem count, stem diameter, plant height, and... |
