Caracterização morfofisiológica e agronômica de Paspalum dilatatum Poir. biótipo Virasoro e Festuca arundinacea Schreb: 2. Disponibilidade de forragem e valor nutritivo Morphophysiological and agronomic characterization of Paspalum dilatatum Poir. biotype Virasoro and Festuca arundinacea Schreb: 2. Forage availability and nutritive value

Este trabalho foi conduzido com o objetivo de avaliar o potencial forrageiro de Paspalum dilatatum Poir. biótipo Virasoro e Festuca arundinacea Schreb., exótica e hibernal na região sul do Brasil. Foi colhida mensalmente a parte aérea de plantas individuais, cultivadas no campo durante 12 meses e avaliadas quanto à disponibilidade de massa seca (DMS), proteína bruta (PB), fibra detergente neutro (FDN) e fibra detergente ácido (FDA). O virasoro apresentou ciclo estacional, com a maior DMS na primavera/verão (98 g MS/planta), enquanto a festuca teve a maior DMS no inverno/primavera (100 g MS/planta). O virasoro mostrou teores mais elevados de PB nas folhas (19,09%) em relação à festuca (17,8%), mas essa apresentou menor conteúdo de FDA (29%) em relação ao virasoro (43%); para FDN nas folhas não houve diferença entre as espécies, com médias de 62%. No colmo, as diferenças foram apenas no outono (festuca=19,9%; virasoro=73,9%). O biótipo Virasoro não foi infectado por Claviceps paspali, que comumente ocorre em P. dilatatum, indicando resistência ao fungo. O biótipo Virasoro detém características desejáveis como planta forrageira, sendo uma boa opção para a estação quente.<br>This work had the objective to evaluate the forage potential of Paspalum dilatatum Poir. biotype Virasoro and Festuca arundinacea Schreb., an exotic species in the southern regions of Brazil. The individual plant shoots were harvested for twelve months, cultivated in the field, and evaluated as for the dry matter availability (DMA), crude protein (CP) and neutral and acid detergent fiber (NDF and ADF). The virasoro showed seasonal cicle, with the maximum DMA in the spring/summer period (98 g DM/plant), while tall fescue had the top DMD in the winter/spring period (100 g DM/plant). The virasoro showed higher CP in the leaves (19,09%) in relation to tall fescue (17.8%), but the latter had the smallest values of ADF (29%) in relation to the former (43%); the ADF in the leaves did not present any differences among the species with the average of 62%. In the culm, the differences were observed only during the fall period (fescue=19.9%; virasoro=73.9%). The Virasoro was not infected by Claviceps paspali, which commonly occurs in P. dilatatum, indicating the possible resistance. The Virasoro biotype own characteristics as forage plant being a good option for the warm season

ALICE: Physics performance report, volume I

ALICE is a general-purpose heavy-ion experiment designed to study the physics of strongly interacting matter and the quark-gluon plasma in nucleus-nucleus collisions at the LHC. It currently includes more than 900 physicists and senior engineers, from both nuclear and high-energy physics, from about 80 institutions in 28 countries. The experimentwas approved in February 1997. The detailed design of the different detector systems has been laid down in a number of Technical Design Reports issued between mid-1998 and the end of 2001 and construction has started for most detectors. Since the last comprehensive information on detector and physics performance was published in the ALICE Technical Proposal in 1996, the detector as well as simulation, reconstruction and analysis software have undergone significant development. The Physics Performance Report (PPR) will give an updated and comprehensive summary of the current status and performance of the various ALICE subsystems, including updates to the Technical Design Reports, where appropriate, as well as a description of systems which have not been published in a Technical Design Report. The PPR will be published in two volumes. The currentVolume I contains: 1. a short theoretical overview and an extensive reference list concerning the physics topics of interest to ALICE, 2. relevant experimental conditions at the LHC, 3. a short summary and update of the subsystem designs, and 4. a description of the offline framework and Monte Carlo generators. Volume II, which will be published separately, will contain detailed simulations of combined detector performance, event reconstruction, and analysis of a representative sample of relevant physics observables from global event characteristics to hard processes. © 2004 IOP Publishing Ltd
