As cultivares de algodoeiro coloridas BRS Safira e BRS Rubi foram obtidas por
meio do cruzamento entre variedades de fibra branca e coloridas. Objetivou-se com essa
pesquisa estudar a composição em ácidos graxos nas sementes de algodoeiro Safira e Rubi, as quais foram analisadas por cromatografia gasosa. Como resultado observou-se que esta cultivar, tem maior concentração de lipídios nas sementes, 23,5%, comparada com as cultivares herbáceas convencionais, que contém média de 14%. No tocante aos ácidos graxos palmítico saturado, tem cerca do dobro do que possuem as cultivares convencionais e quanto aos ácidos graxos linoléico, tem média de 33,13%, enquanto nas sementes herbáceo tradicionais a média é de 47,8%. Já o teor de óleo da cultivar Rubi, é em média de 24,28%, possui os lipídeos da semente diferentes das cultivares brancas, acompanhando os teores da Safira, especialmente, no tocante aos ácidos graxos palmítico, saturado, que é cerca do dobro do normal nas cultivares de algodão comum. O ácido graxo linoléico, que é predominante no algodão branco, com 54,54% , já na Rubi, é bem mais baixo, com 31,88%. Os resultados demonstraram que as duas variedades apresentaram teores superiores constituintes acima da variedade de fibra branca. |

The Guapi-Macacu watershed is located in the Brazilian state of Rio de Janeiro, has a drainage area of about 1.640 km2, and drains into the Guanabara Bay northeast of the metropolitan area. The upper catchment in the Serra dos Órgãos mountain range is covered by dense old-growth forest of high biological diversity, while pastures and agricultural land dominate in the lower catchment. Apart from its outstanding biological value, the watershed provides crucial services including water supply to 2.5 million inhabitants in five municipalities. Nevertheless, forests and soils in the lower watershed are highly degraded due to the expansion of the agricultural frontier, overexploitation, and suburbanisation processes. Several pressures on this ecosystem persist. Therefore payments for ecosystem services (PES) schemes are proposed by local initiatives and supported by international organizations as a suitable instrument to deal with the trade-offs between agricultural use and watershed services in a cost-effective manner. Studying the provision costs of and the demand for watershed services can support decision making process to evaluate the scope and economic feasibility of PES and alternative management options. Water resources in the watershed are of extreme importance for agriculture and also for industries, such as water bottle companies, breweries and the biggest Brazilian petrochemical complex, COMPERJ. Our study concentrates on calculating the opportunity costs related to the provision of watershed services under varying land use systems and evaluating the feasibility of PES related aspects, such as preserving or recovering forest areas and integrating good agricultural practices. Watershed services are valued in terms of controlling nutrients (Nitrogen and Phosphorus in surface water) and sediment loads (measured in terms of turbidity and total solids). Replacement and avoided cost methods are applied focusing on the local water treatment facility to estimate demand for service maintenance and improvement. To provide empirical evidence of the link between land use and water quality indicators, we rely on water quality modelling and monitoring specifically adapted to this area. Spatial conservation opportunity cost analysis is used to study the costs of watershed services maintenance and improvement and derive implication for cost-effective management on the basis of scenario analyses. The research activities take place within the framework of the multi-disciplinary German-Brazilian cooperation project DINARIO/MP2.
