O presente trabalho tem como objetivo analisar como o Movimento dos Pequenos Agricultores vem organizando sua luta em defesa das sementes crioulas no estado de Sergipe a partir de ações do Território do Alto Sertão Sergipano. As informações que foram analisadas neste trabalho partiram de leituras do Plano Camponês e do Plano Nacional de Sementes Crioula do MPA. Além isto, através da observação-participante, buscou-se ivenciar a realidade do Movimento durante o encontro de agricultores(as) guardiões e guardiãs das sementes crioulas (2016) no município de Poço Redondo/SE. O MPA vem realizando uma luta ampla contra o avanço do agronegócio no Alto Sertão Sergipano. Neste sentido, a defesa das sementes crioulas representa uma simbologia na resistência da agricultura camponesa, ao mesmo tempo que nos remete a um novo paradigma de desenvolvimento do campo baseado nos princípios da Agroecologia. |

The cellulose industry in Brazil uses, mainly, hybrids between Eucalyptus grandis x E. urophylla. Not only the volume but also the wood density has great influence in the cellulose productivity, therefore a selection for both characteristics should be done as an alternative to increase the improvement program efficiency. The present work has been carried out with the objective of comparison between Open Pollinated progenies (OP) and hybrids performance in E. grandis and E. urophylla. To do so, 15 OP progenies of E. grandis, 15 OP progenies of E. urophylla, and 15 hybrids between E. grandis x E. urophylla, plus four controls were evaluated. The experiment was carried out from October to November 2001, in three sites, Aracruz and São Mateus, in the Espírito Santo State, and Caravelas, Bahia State, Brazil, in a 14 x 14 lattice design, involving the 49 treatments mentioned plus other progenies not considered in this article, with single tree plots and 40 replicates. Two years later the circumference at breast height (CBH) and the basic wood density (BWD) were evaluated. The hybrids performance for CBH was higher, an average, 38,7% than the OP progenies for both species. Part of the heterosis in relation to parental means could be attributed to the inbreeding depression due to selfing that occurred in the OP progenies and the dominance controlling this character. For the BWD the hybrids performance was the same of the OP progenies. Since there was divergence between the parents, it can be inferred that dominance has no importance for this trait. The negative correlation between the CBH and the BWD could impair the simultaneous selection for both traits, depending on the wood basic density range used by the industry.
