Este artigo defende a tese de que a produção do espaço urbano, nos termos da Constituição Federal de 1988, é um serviço público de competência municipal e não uma atividade econômica livre à inciativa privada e regulada pelo poder público. Partindo de uma crítica às leituras que tradicionalmente são feitas da Lei de Parcelamento de Solo e do Estatuto da Cidade, o texto descreve os princípios fundamentais do Direito Urbanístico Espanhol, como paradigma de comparação, para buscar os fundamentos que permitem afirmar a tese proposta em face do Direito Urbanístico Brasileiro. Por fim, o Reordenamento Urbanístico Integrado, tal como previsto no Plano Diretor de São Paulo, é estudado e destacado como um caso de publicização da produção do espaço urbano, demonstrando que os municípios têm respaldo na Ordem Constitucional Brasileira para criar instrumentos de política urbana que lhes possibilitem apropriar a produção do espaço urbano como um serviço público.
<p class="Pa7">The aim of this study was compare some techniques to assess the adaptability and stability seeking the selection of wheat genotypes in Paraná State. The grain yield data were obtained from trial experiments of the Value of Cultivation and Use, as assessed in 44 different locations in distributed environments and sowing date. The study of adaptability and stability were evaluated based on Eberhart and Russell (1966), Lin and Binns (1988) revised by Carneiro (1998), Porto, Carvalho and Pinto (2007) and Rocha et al. (2005). The methods of Eberhart and Russell (1966), Lin and Binns (1988) revised by Carneiro (1998), and the method of Porto, Carvalho and Pinto (2007) showed similar results. These methods were superior to the method of Rocha et al. (2005), which was sloppy in the selection process. The method of Porto, Carvalho and Pinto (2007) had the advantage of simplifying the analysis of adaptability and stability.</p>
