This study aimed to evaluate the effect of different planting densities and phosphorus fertilization on yield, chemical and mineral composition of Pornunça (Manihot sp.) cultivated under rainfed system, from May 2010 to October 2011. It was adopted the randomized blocks design in a factorial 4 x 4 with three replications, 4 spacing (1.5 x 1.5, 1.5 x 2.0, 2.0 x 2.0 and 2, 5 x 2.0 meters) and 4 phosphorus levels (0.0, 56.66, 113.32 and 169.98 g plant-1 superphosphate). For the total dry mass (TDM) of Pornunça there was effect (P=0.023) isolated from different plant spacing used, and the spacing 1.5 m x 2.0 m provided greater TDM. The planting spacing and phosphorus fertilization showed interaction effect (P<0.05) in the chemical composition only for organic matter and mineral composition presented individual effect for phosphorus levels in the soil and in the phosphorus content of Pornunça plant. For the other variables, there was no effect on the interaction and individual factor (planting spacing and phosphorus fertilization). In dry conditions, planting spacing influences the dry matter forage production and organic matter Pornunça, presented greater value for both the spacing of 1.5 m x 2.0 m. Fertilizing with simple superphosphate increases soil organic matter of Pornunça, until the dosage of 56.66 g plant-1 in the spacing of 1.5 m x 2.0 m, and linearly for the phosphorus content of the plant used regardlessof spacing. |

The frequency of meiotic abnormalities among single-, double- and three-way cross experimental hybrids and their parental inbred lines is studied. Among the sixteen inbred lines examined, fifteen originated from populations developed at the National Center of Research in Maize and Sorghum (CNPMS/Embrapa) and one from a population developed at ESALQ (Faculty of Agriculture Luiz de Queiroz of the University of São Paulo). Previous analyses of homozygous and heterozygous maize genotypes from CNPMS populations demonstrated high meiotic instability. The present investigation aims at analyzing the meiotic behavior of different inbred lines obtained from CNPMS populations by another breeding enterprise to verify the presence of the same abnormalities and determine whether the abnormalities might compromise productivity. Analyses showed the presence of some abnormalities described previously, albeit at a lower frequency. The most common abnormalities in homozygous and heterozygous genotypes from CNPMS populations were related to irregular chromosome segregation and to chromosome stickiness. An inbred line from the ESALQ population showed only abnormalities related to irregular chromosome segregation caused by the presence of univalent chromosomes. The Pearson correlation procedure indicated high negative correlation between meiotic abnormalities and productivity. |
