No. of bitstreams: 1 EmileRochaDeLima_DISSERT.pdf: 2345528 bytes, checksum: 4e4dc72bbdbe79ee0363c56322fe405d (MD5) Previous issue date: 2015-02-20 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / As novas estrat?gias de desenvolvimento devem atuar principalmente nas ?reas de efici?ncia energ?tica e agricultura sustent?vel. Desta forma, a substitui??o de combust?veis f?sseis por biocombust?veis, como o biodiesel, est? cada vez mais em pauta. O cultivo de plantas oleaginosas para a produ??o de biodiesel deve acontecer em sistemas integrados que permitam melhores benef?cios ambientais e sejam mais significativos socioeconomicamente. Assim, os objetivos do presente estudo foram: avaliar as caracter?sticas morfoanat?micas e fisiol?gicas de plantas de c?rtamo (Carthamus tinctorius L., oleaginosa promissora para a produ??o de biodiesel) cultivadas em monocultivo e em cons?rcio com o feij?o caupi (Vigna unguiculata L. Walp.); al?m de caracterizar socioeconomicamente agricultores familiares e verificar a aceita??o deles acerca do c?rtamo como cultura energ?tica. A metodologia utilizada para as an?lises de crescimento do c?rtamo em monocultivo e consorciado com o feij?o, foram an?lises morfoanat?micas e histoqu?micas, feitas com amostras de plantas cultivadas em campo, nos dois sistemas de cultivo. N?o houve altera??es no crescimento e anatomia das plantas, mesmo em cons?rcio, o que ? satisfat?rio para indicar o sistema consorciado para essas culturas e pode ser uma boa alternativa para o produtor familiar, que pode ter o c?rtamo como fonte de renda, sem precisar abdicar de plantar sua fonte de subsist?ncia. Para a verifica??o da aceita??o do c?rtamo por agricultores, foram feitas entrevistas a agricultores familiares da agrovila Canudos, em Cear?-Mirim/RN. Percebeu-se que boa parte deles aceitam a introdu??o do c?rtamo como cultura oleaginosa, apesar de desconhecerem a esp?cie, al?m de que, por ser mais resistente ? seca, o c?rtamo auxiliaria na estabilidade das fam?lias, que dependem das condi??es do clima para o sucesso de seus cultivos atuais. De maneira geral, conclui-se que o c?rtamo possui caracter?sticas que o permite ser cultivado em cons?rcio para a produ??o de biodiesel aliada ? produ??o de alimentos, como o feij?o caupi, e pode ser utilizado possibilitando melhor desenvolvimento para a agricultura familiar. / The new development strategies should operate mainly in the areas of energy efficiency and sustainable agriculture. Thus, the substitution of fossil fuels with biofuels, such as biodiesel, is increasingly on the agenda. The cultivation of oilseed plants for biodiesel production must take place in integrated systems that enable best environmental benefits and are more economically significant. The objectives of this study were to assess the morphological, anatomic, and physiological characteristics of safflower (Carthamus tinctorius L., promising oilseed for biodiesel production) grown in monoculture and intercropping with cowpea bean (Vigna unguiculata L. Walp.); and identify socioeconomic family farmers and verify their acceptance about safflower as an energy crop. The methodology used for the analysis of safflower growth in monoculture and intercropped with beans, were morphoanatomical and histochemical analyzes, made with samples of plants grown in the field in two cropping systems throughout the range of the life cycle of these plants. There were no changes in growth and anatomy of plants, even in the consortium, which is satisfactory to indicate the intercropping system for those crops and can be a good alternative for the family farmer, who may have safflower as a source of income without giving up planting their livelihood. To check the acceptance of safflower by farmers, interviews were made to family farmers by Canudos agrovila in Cear?-Mirim/RN. It was noticed that many of them accept the introduction of safflower as oil crop, although unaware of the species, and that, being more resistant to drought, safflower help in the stability of families who depend on the weather conditions for success their current crops. In general, it is concluded that safflower has features that allows it to be grown in consortium for biodiesel production combined with the production of food, such as cowpea, and can be used enabling better development for family farmers.
