Abstract: the research aimed to evaluate the decomposition of sabiá (mimosa caesalpiniifolia benth) litter fractions by using the nylon bag technique. the following litter fractions were incubated: senescent leaves, leaves at the beginning of mineralization, and branches with diameter up to 20 mm. incubation was performed during periods of 0, 4, 8, 16, 64, 100, and 256 days in 2006 and 2007. the fractions were distributed in a random block design with five replications. it was evaluated the disappearance of biomass, nitrogen (n), and phosphorus (p), concentrations of nitrogen and phosphorus and the carbon/ nitrogen ratio of litter during the periods of incubation. in general, the negative exponential model explained the disappearance of biomass, nitrogen, and phosphorus, however, there was a variation among years and, in some cases, despite of being significant, the models showed a low correlation between predicted and observed data. biomass disappearance rate was slow because only 30% of leaf biomass was mineralized after 256 days of incubation. net nitrogen mineralization showed large variation among years, and it differed among the studied fractions. nitrogen content of the litter increased, on average, until 32 days (leaves) and until 64 days (branches) of incubation followed by stabilization. the linear plateau model was used to explain that process. in the course of the incubation periods, the carbon/nitrogen ration decreased. despite of the high content of nitrogen, the decomposition of sabiá litter is slow, what might reduce the loss of nutrients in the forest, increasing its sustainability and reducing the possible deleterious effects to the environment.

Abstract: the objectives in this work were to study the association between the morphological and productive characteristics in pennisetum sp. clones, and to identify the morphological characteristics responsible for the productivity in pennisetum cp. clones. the canonical correlations were evaluated and the path analysis was made from the simple genotypic correlation matrix between the morphological and productive characteristics of eight pennisetum sp. clones (taiwan a-146 2.37, taiwan a-146 2.27, taiwan-146 2.114, merker méxico mx 6.31, mott, hv-241, elefante b and iri-381). the canonical correlations were significant at 1% probability by the chi-square test. the first pair of canonic factors, with correlation of 0.9999, related the plants with the highest dry matter content to plants with lower leaf area indexes, light perception and leaf angle. the second pair of canonic factors, with correlation of 0.9999, related the plants with the highest dry matter production to the plants with higher basal tiller density, height, and low green leaf number per tiller. the results of the path analysis indicated that the light interception is determinant in dry matter content expression of pennisetum sp. clones, while the basal tiller density and plant height are responsible for dry matter production in these clones.

Abstract: this research was carried out at to evaluate the variability and heritability of morphologic traits in 54 elephant grass clones (three local controls and 51 from the renace/cnpgl) in the forest zone in pernambuco. it was used a complete randomized block design with additional controls. three cuts were performed on the 60th day of regrowth. there were significant differences for stem diameter, basal and aerial tillers density, width of leaf 3, length of leaf 5, leaf blade percentage, stem percentage, and leaf/stem ratio. clones of renace are similar to the ones traditionally cultivated in the conditions of forest zone in pernambuco regarded to morphological characters. cultivar pioneiro showed early flourishing in the environmental conditions of this study. number of basal and aerial/metter tillers showed good heritability, evidencing little influence of the environment on variability among the clones. considering the variability among renace clones for basal and aerial tillers/m and leaf/stem ratio and the high heritability of these characters, it is possible to obtain genetic gains for these traits in the elephant grass breeding program in the forest zone in pernambuco.
