The success of native vegetation reclamation depends upon the knowledge about the species and planting strategies/models best suited for the area to be recovered. This work suggests more than 200 native species with their physiognomies of occurrence for the Cerrado biome, associated to its ecological strategy of occupation (covering or diversity) and main categories of potential economic utilization for using in eight planting strategies/models. It aims to guide technicians and owners of rural areas on the choice of species and appropriate strategies for woody (forest and savannah) vegetation recovery of Cerrado biome. Strategies for restoration with woody native vegetation vary from passive actions, as natural regeneration, to high intervention actions, such as those in Agroforestry Systems. Areas with greatest potential for natural regeneration have presence of regenerating seedlings, greater cover of native vegetation nearby and low presence of exotic and local competitors and it requires less labor and costs while areas with low potential for natural regeneration demand intense intervention and more expensive technics. All restoration action has risks and must be monitored and managed according to the expected results. These actions will indicate if your strategy was adequate and well conducted. Actions should start in small areas to support new decisions if something fails. To attend the law of Protection of Native Vegetation, these strategies can be applied in Brazil for Legal reserve (ARL) and Permanent Preservation (APP) areas.

To meet the demands of the production chain, breeding programs need to reduce the time for selection and development of higher yielding maize genotypes. This involves application of new strategies, such as the use of the doubled haploid lines. We evaluated the use of stomatal area and density in distinguishing doubled haploids (DH) from false positive (FP) plants derived from nine tropical source populations. We selected four DH plants and two FP plants for identification of DH through leaf anatomy in the populations, in each group. Data on stomatal area and density were considered in a completely randomized model in a factorial scheme (populations and genotypes) and analyzed by restricted maximum likelihood. There were statistically significant effects of populations and genotypes for both traits. For stomatal density, the population by genotype interaction was not verified. Stomatal density proved to be efficient for distinguishing DH and FP for use in selection of doubled haploids. |
