The objective of this work was to evaluate three tropical forage species for their in vitro methane (CH4) production and organic matter degradability, in order to determine the relationships between forage grass nutritive quality and CH4 production. Guinea grass (Megathyrsus maximus), palisade grass (Urochloa brizantha), and signal grass (Urochloa decumbens) were evaluated. Palisade grass showed the highest organic matter, neutral detergent fiber, acid detergent fiber, lignin, and lower-crude protein content. Signal grass had the highest values for hemicellulose and neutral detergent fiber-nitrogen, and the lowest-cellulose content. Guinea grass and signal grass showed a higher-total gas production than palisade grass. Besides, Guinea grass showed an increased CH4 production, and palisade grass showed lower value for truly degraded organic matter, and reduced partitioning factor, in comparison to signal grass. An increased CH4 production was observed in cases of lower hemicellulose and paratitioning factor. The nutritive value and CH4 production of forages may be employed as parameters, aiming at the sustainability of ruminant production. |

During the 1995/96 growing season, Fusarium graminearum Schwabe, a pathogen of various winter cerals and corn, was isolated from soybean seeds produced in the Northern region of the state of Santa Catarina, Brazil, in an area where susceptible crops have been cultivated in previous years. This fact demanded studies to prove the association of the fungus with the soybean crop. Twenty seven monoascosporic cultures of the fungus isolated from soybean seeds and one from wheat seeds were used in this study. Inoculation of F. graminearum was done by the toothpick method and by wheat seeds colonized with the fungus. Only the toothpick method was effective to cause infection in inoculated plants. In this method, it was determined that the period of incubation of the toothpick in culture media containing the fungus did not affect the results of the inoculation. On the other hand, the age of the plants at the inoculation time was a factor that affected the infection rate of inoculated plants. Twenty-three-day old plants showed the highest infection rates. Inoculation of the 28 isolates to soybean cultivars 'BR-16' and 'FT-Abyara' showed that 'BR-16' was more susceptible than 'FT-Abyara' Although all isolates were able to infect the plants after inoculation, they did not kill the plants or transmitted the fungus systemically to the new seeds. The results of this study indicate that Fusarium graminearum may occur in plants and seeds however it is not pathogenic to soybean. |
