Reducing competition in agroforestry by pruning native trees.
The degree to which pruning helps reestablish balance in agroforestry was assessed in a system established in São Carlos, São Paulo, Brazil, in 2008. Seven native tree species were planted at a density of 600 trees/ha in five strips of three rows each, and annual crops were cultivated in the 17-m crop strips between the tree strips. Competition was established after 35 months, decreasing the aboveground biomass production of corn planted close to the trees. An assessment of black oats in the dry season following tree pruning showed that the proximity of trees caused reductions in plant and panicle density, aboveground biomass production, number of grains per panicle and grain weight. Because pruning was not sufficient to maintain crop yields, tree thinning is recommended in order to minimize competition and restore conditions for adequate crop production
Análise haplotípica do gene ASAP1 associado com maciez de carne em bovinos da raça Nelore.
A maciez da carne tem impacto importante na satisfação dos consumidores, portanto, o conhecimento da variação desta característica, assim como a prospecção de genes ou segmentos genômicos que influenciem a mesma, pode ajudar no desenvolvimento de critérios quantitativos e moleculares para seleção de bovinos de corte. A análise haplotípica com os SNPs do gene ASAP1 representados no Illumina BovineHD BeadChip mostram que estes marcadores estão associados com força de cisalhamento medida após 7 dias de maturação da carne nessa população da raça Nelore. A validação desses resultados em outras populações poderá contribuir para inclusão desses marcadores em programas de melhoramento da raça Nelore
