Abstract: the objective of this work was to evaluate the genetic parameters estimated in intra and interespecific hybrid families of elephant grass under two evaluation strategies: per se and genetically stratified mass selection. ten families of intraespecifc hybrids and ten families of interespecific hybrids were used. the characteristics evaluated were the following: plant height, plant agronomic score, dry matter content and dry matter production. it was estimated, for genetic parameters, heritability in the wide sense, variance, genetic and experimental variation coefficient and genetic, phenotypic and environmental correlation. the experiment was evaluated in a random block design with three repetitions. greater genetic variability for the studied characteristics were observed among the interespecific hybrids of elephant grass and pearl millet in comparison to the intraespecifc hybrids of elephant grass. heritability showed higher percentages for per se strategy among the studied hybrids. genetically stratified mass selection is less effective in removing the environmental effects aiming at improving experimental precision.

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.
Avalia??o de clones de capim-elefante (Pennisetum purpureum Schum.) e de um híbrido com o milheto (Pennisetum glaucum (L.) R. Br.) submetidos a estresse hídrico. 1. Parametros morfológicos

Abstract: this trial was carried out to evaluate the morphological characteristics of three elephant grass clones (cameroon, roxo de botucatu and mott) and an elephant grass with pearl millet hybrid (hv-241) submitted to two humidity regimes (with and without water stress). a randomized block design with split plots and three replicates was used. in the main plot, the effect of the humidity regimes was studied, and in the split plot, the different clones. plants submitted to water stress showed lower height, and none of them showed internodes above cutting height (10 cm). as a result of water stress, the plant height reductions were 42.7% (cameroon), 35.05% (roxo de botucatu), 28.54% (hybrid hv-241) and 27.43% (mott). leaf blade length was reduced from 69.9 cm, in the wet treatment, to 50.0 cm in those submitted to water stress, whereas leaf blade width average of water stress plants was less than a half of that in wet treatment plants. water stress did not disturb tillering of cultivars but, in hv-241 hybrid, it reduced both the number of lateral tillers/plant and total number of tillers/plant. in both humidity regimes, hybrid hv-241 was the clone, which showed the largest tillering. it was observed that, except for tillering of cultivars, water stress promoted a reduction on the other morphologic studied parameters.
