1. Software Selegen-REML/BLUP: a useful tool for plant breeding
Abstract The software Selegen-REML/BLUP uses mixed models, and was developed to optimize the routine of plant breeding programs. It addresses the following plants categories: allogamous, automagous, of mixed mating system, and of clonal propagation. It considers several experimental designs, mating designs, genotype x environment interaction, experiments rep

2. Induction of insect plant resistance to the spittlebug Mahanarva fimbriolata Stål (Hemiptera: Cercopidae) in sugarcane by silicon application
Changes in the agroecosystem with the increase of green cane harvesting in Brazil affected the insect populations associated to this crop, and secondary pests like the spittlebug Mahanarva fimbriolata Stål, became much more important. Many studies have demonstrated the active role played by silicon in plant defense against herbivory. The objective of this s

3. Inbreeding depression in Vriesea gigantea, a perennial bromeliad from Southern Brazil
Vriesea gigantea is a bromeliad distributed in the Atlantic Rainforest, Southeastern Brazil. It is characterized by the presence of tanks which are used as an important source of resources by populations of associated biota. Habitat destruction, fragmentation and predatory colection have decreased natural populations of V. gigantea. Inbreeding depression is

4. Estudo da diversidade genetica e da taxa de cruzamento em Stylosanthes spp. atraves de marcores microssatelites / Genetic diversity and mating system in Stylosanthes spp. as revealed by microsatellite markers
In Brazil, most of the cattle are grown in cultivated pastures. Forage grasses belonging to the African genus Urochloa P. Beauv. have been the most commonly used, together with some American legumes. Soil degradation and high costs for reclaiming are the major problems of pastures, since nitrogen enrichment is necessary. Considering that legumes can fix atmo

5. Biologia da polinização e reprodução de especies de Melastomataceae do Parque Nacional da Serra da Canastra (MG) / Pollination and reproductive biology of Melastomataceae from Serra da Canastra National Park (MG, Brazil)
This study examines the reproductive phenology, pollination ecology, and mating systems of 10 species of Melastomataceae that occur in the Serra da Canastra National Park, Minas Gerais. Seasonality exposes plants to periodic changes in quality and abundance of resources. Flowers of many species can be found throughout the year, but there are well-defined pea

6. Coccinellidae (Coleoptera) usando plantas aromáticas como sítio de sobrevivência e reprodução em sistema agroecológico, e aspectos biológicos em condições de Laboratório / Coccinellidae (Coleoptera) using aromatic plants as survival and reproduction site in agroecological system, and biological aspects under laboratory conditions.
Among the natural enemies of agriculture pests, the Coccinellidae predators are detached. Some coccinellids only complete their development and produce viable eggs and progenies when they consume their preferred prey. However, when this prey is scarce or in presence of a prey of low quality, certain coccinellids feed on alternative food resources, such as ex

7. Análise da estrutura genética de populações e sistema reprodutivo de Oryza glumaepatula por meio de microssatélites / Genetic structure and mating system of Oryza glumaepatula steud. populations using microsatellite markers
Informations about genetic structure and breeding systems are little and poorly of natural O. glumaepatula populations. The objective of this study was the characterization of the genetic structure of 11 populations from Japura, Solimoes, Purus, Negro, Xingu and Tapajos rivers (from Amazon Hidrographic Basin) and from Paraguai and Taquari rivers (from Paragu

8. Diversidade genética e fluxo gênico via pólen e semente em populações de Solanum lycocarpum ST.HIL. (Solanaceae) no sudeste de Goiás / Genetic diversity and gene flow by pollen and seed in populations of Solanum Lycocarpum St.Hil. (Solanaceae) in the southeast of the state of Goiás
Solanum lycocarpum St.Hil. (Solanaceae) is a woody plant that is found in the Brazilian Cerrados (savanna fields) in Central Brazil. It is heliophile, and it features open secondary formations. Its popularly known as wolfs fruit. The meat of its fruit is used in the production of a phytomedicine, the wolfs fruit powder, which is traded in the form of capsule

9. Mating system of a population of Myracrodruon urundeuva F.F. & M.F. Allemão using the fAFLP molecular marker
The mating system and genetic diversity were studied in a natural population of Myracrodruon urundeuva originating from 30 open-pollinated trees at the Paulo de Faria Ecological Station, SP, Brazil. The progenies were planted on the Teaching and Research Farm of the Ilha Solteira Engineering School, UNESP. Using the fAFLP molecular marker, eleven loci were s

10. Genetic structure in bracatinga populations (Mimosa scabrella Benth.) for quantitative traids and isozyme markers. / Estrutura genética em populações de bracatinga (Mimosa scabrella Benth. ) por marcador isoenzimático e caracteres quantitativos.
Mimosa scabrella Bentham (Bracatinga), is a native tree species of Atlantic Forest, of restricted occurrence to the Southwest and South of Brazil (RS, SC, PR and SP). The species comes being cultivated in the Brazil south and in the other countries as Costa Rica and Ruanda, for the most varied ends. But, although the species has a varied ends, lack studies i

11. Caracterização genética de populações de cupuaçuzeiro, Theobroma grandiflorum (Willd. ex. Spreng.) Schum., por marcadores microssatélites e descritores botânico-agronômicos. / Genetic characterization of cupuassu theobroma grandiflorum (willd. ex. spreng.) schum. populations by microsatellite markers and botanic-agronomic descriptors.
This work had the objectives to characterize and compare the genetic structure of seven populations of cupuassu, Theobroma grandiflorum (Willd. ex Spreng.) Schum., a fruit tree native to the Brazilian Amazon using microsatellite markers and botanic-agronomic descriptors; and to investigate the cupuassu mating system. The genetic structure of seven population

12. Ecologia comportamental e de interações com plantas hospedeiras em Phyllophaga cuyabana (Moser) (Coleoptera:Melolonthidae, Melolonthinae) e implicações para o seu manejo em cultura de soja
Soybean (Glycine max (L.) Merrill) is an introduced crop which has been expanding in Brazil during the last four decades. There are still some nutricional niches unoccupied or inefficiently explored by arthropods and other colonizing herbivores. Some insects with subterranean habitat have been considered soybean pests in Brazil in the last ten years, probabl
