1. Maintenance of wetland plant communities: the role of the seed bank in regeneration of native plants
ABSTRACT Exotic grasses have been introduced into wetlands and can compete with native plants due to their high tolerance of flood and dry periods. Flooding can facilitate seed dispersal of exotic species and reduce the diversity of native species. We compared two grasslands to assess whether seed banks can maintain the diversity of native plants in wetlands

2. Interaction between growth strategies and phosphorus use efficiency in grasses from South America natural grasslands
ABSTRACT South American natural grasslands are composed of several species with different growth strategies, with variations in specific leaf area (SLA), leaf dry matter content (LDMC), specific root length (SRL) and specific root area (SRA). The objective of this study was characterizing in grasses cultivated with different levels of phosphorus (P) in the s

3. Growth dynamics of the branching system in grasses: an architecture-based methodology for quantitative evaluation applied to two genotypes of Paspalum vaginatum
Resumo Foi estudada a dinâmica do crescimento dos caules aéreos de Paspalum vaginatum, uma gramínea de ampla distribuição. Com o objetivo de identificar características diferenciais quantitativas entre dois genótipos, as plantas foram cultivadas ao ar livre em vasos durante dois verões consecutivos. Os eixos de diferentes ramificações foram marcado

4. Growth of Tree Species in Coexistence with Palisade Grass Urochloa brizantha (Hochst. ex A. Rich.) Stapf CV. Marandu
RESUMO: Avaliou-se neste trabalho o efeito da presença do capim-braquiarão (Urochloa brizantha) sobre o crescimento de cinco espécies arbóreas do bioma Mata Atlântica, em Seropédica-RJ. O estudo abrangeu cinco experimentos em delineamento inteiramente casualizado. Em cada experimento, testou-se em vasos o efeito da gramínea sobre o crescimento das esp

5. Mitigation of Mombasa Grass ( Megathyrsus maximus ) Dependence on Nitrogen Fertilization as a Function of Inoculation with Azospirillum brasilense
ABSTRACT Using biological inputs to improve the efficiency of nitrogen fertilizers represents an alternative for the cultivation of grasses in tropical regions. Azospirillum brasilense is a species of plant growth promoting bacteria widely studied and used in inoculants. Thus, this study aimed to evaluate the performance of Mombasa grass ( Megathyrsus maximu

6. Endophytic fungi from Brachiaria grasses in Brazil and preliminary screening of Sclerotinia sclerotiorum antagonists
ABSTRACT: Fungal endophytes of Brachiaria, a nonhost of Sclerotinia sclerotiorum, may harbor species with antagonistic effects against this plant pathogen. The objective of this work was to investigate the diversity of endophytic fungi associated with different Brachiaria species and hybrids and evaluate their potential to inhibit the plant pathogen S. scler

7. Morphophysiology of buffel grass grown under different water supplies in the dry and dry-rainy seasons
RESUMO A carência de informações sobre o crescimento de gramíneas forrageiras em ambiente semiárido, sobretudo sob a perspectiva de irrigação, é um dos entraves para a oferta regular de forragem, assim como para o uso racional da água de irrigação. Diante do exposto, objetivou-se avaliar as trocas gasosas foliares, o fluxo de biomassa e as caracte

8. Maize Productivity, Mycorrhizal Assessment, Chemical and Microbiological Soil Attributes Influenced by Maize-Forage Grasses Intercropping
Abstract Mycorrhizae are important components of agroecosystems and the diversification of crops stimulates the abundance of arbuscular mycorrhizal fungi and the participation of symbiosis in plant growth. This experiment examined mycorrhizal assessment, chemical and microbiological soil attributes in a maize-forage grasses intercropping compared to a maize-

9. Production of Fodder in a Treeless System and in Silvopastoral System in Central Argentina
ABSTRACT This paper aims to identify the spatial and temporal distribution of net aerial primary production (NAPP) of oats and sorghum in silvopastoral systems (SPS) and in a treeless situation (TLS), in Southern Cordoba, Argentina. The silvopastoral systems are composed of three woody cultures (Pinus elliottii, Eucalyptus viminalis and Quercus robur), and

10. Fungal endophytes of Panicum maximum and Pennisetum purpureum: isolation, identification, and determination of antifungal potential
ABSTRACT This study aimed to isolate and identify endophytic fungi from the forage grass P. maximum and evaluate their ability to inhibit the growth of plant pathogenic fungi. One sample from P. purpureum grass was also included. Surface disinfected stem fragments were used for endophytic fungal isolation. One hundred and twenty-six endophytic fungi were iso

11. Agronomic and molecular characterization of wild germplasm Saccharum spontaneum for sugarcane and energycane breeding purposes
ABSTRACT: Among the species related to sugarcane, Saccharum spontaneum (L.) is a wild species with the greatest potential as a source of genetic variation to cope with biomass production in harsh environments. Due to its high yield, early vigor, ratooning ability, low input requirements and tolerance to various biotic and abiotic stresses, sugarcane breeders

12. Intraspecific tetraploid hybrids of Paspalum notatum: agronomic evaluation of segregating progeny
ABSTRACT: For many decades, animal production in southern Brazil has been based on native forage grasses. Paspalum notatum Flügge (bahiagrass) is one of the most frequently used native grass in southern Brazil. The native germplasm of P. notatum is tetraploid and displays apomictic reproduction; hence, chromosome doubling of sexual diploid accessions is req
