Conteúdo:  Cotton produces one of the most important textile fibers of the world and has great relevance in the world economy. It is an economically important crop in Brazil, which is the world's fifth largest producer. However, studies evaluating the genotype x environment (G x E) interactions in cotton are scarce in this country. Therefore, the goal of this study was to evaluate the G x E interactions in two important traits in cotton (fiber yield and fiber length) using the method proposed by Eberhart and Russell (simple linear regression) and reaction norm models (random regression). Eight trials with sixteen upland cotton genotypes, conducted in a randomized block design, were used. It was possible to identify a genotype with wide adaptability and stability for both traits. Reaction norm models have excellent theoretical and practical properties and led to more informative and accurate results than the method proposed by Eberhart and Russell and should, therefore, be preferred. Curves of genotypic values as a function of the environmental gradient, which predict the behavior of the genotypes along the environmental gradient, were generated. These curves make possible the recommendation to untested environmental levels.

Conteúdo:  Due to a new climatic reality that we have together , which causes scarcity of water resources, increased salinity and constant temperature change, increasingly we to obtain plants able to adapt to abiotic stresses, which have a great impact on their growth and productivity. To minimize the adverse effects caused by theses factors, the plant starts production of molecules involved in response and is essential for their survival, as HSPs (heat shock proteins). These molecules are responsible for protein folding, assembly, translocation and degradation in a broad array of normal cellular process; they also function in the stabilization of proteins and membranes, and can assist in protein refolding under stress conditions (Wang et al., 2004). The paper aims is generate transgenic C. papaya expressing sHsps obtained from Musa acuminata leaves subjected to heat and e cold, and evaluate the correlation betwen the response to abiotic stresses with the differential expression of these proteins. For genetic transformation, green fruit open pollinated "Sunrise" papaya, harvested 90 to 120 days after fruit set, was obtained, from germplasm bank from Embrapa Cassava and Tropical Fruit. Immature zygotic embryos were surface-sterilized with 70% ethanol followed by immersion in 1% sodium hypochlorite for 20 min and then rinsed three times in sterile water. The embryos were placed on induction medium that was the same as that reported by Fitch et al. (1990). For each bombardment test h... Mostrar Tudo
