Resumo: | The objective of this study was to verify the occurrence of Dioscorea trifida in Brazil and to obtain information concerning its distribution, management and diversity. Farmers from 21 communities were interviewed in the states of Sao Paulo, Santa Catarina and Mato Grosso. During the visits, semi-structured interviews were conducted to collect socio-economic, management and diversity data for this crop. Fifty-one collected accessions, plus two accessions obtained at local markets of Amazonas, were characterized using 12 morphological traits. Most the interviewed farmers were men (75%) with a mean age of 59.5 years. Just a few young people and labor force were available for agricultural activities, with an average of only three individuals per farm. Most farmers (56%) grew only one variety of D. trifida, although 44% had more than one variety in their fields, which aims to provide greater assurance at harvest. Many popular names were observed for D. trifida, and cara roxo (purple yam) was the name most used by farmers (43.4%). Characters referring to the tuber, such as skin and flesh color, were most relevant for the distinction of the accessions. The results of this study may collaborate to develop strategies for conservation, both ex situ and in situ, within the view of on farm conservation. |

Para tanto, foram visitados e entrevistados agricultores de 21 comunidades, nos Estados de São Paulo, Santa Catarina, Mato Grosso. Durante as visitas, foram realizadas entrevistas semi-estruturadas visando obter dados sócioeconômicos, de manejo e diversidade da cultura. Cinquenta e um acessos, além de dois acessos adquiridos em feiras no Estado do Amazonas, foram caracterizados por meio de 12 descritores morfológicos. A maioria dos entrevistados era homem (75%) com média de idade de 59,5 anos. Observou-se um número reduzido de jovens e mão de obra disponível para as atividades agrícolas, cerca de três indivíduos por roça. A maior parte dos agricultores (56%) cultiva apenas uma variedade de D. trifida, embora 44% tenham declarado o cultivo de mais de uma variedade, procedimento que visa dar maior garantia de colheita. Vários nomes populares foram observados para D. trifida, sendo cará roxo, a denominação mais utilizada pelos agricultores (43,4%). Os caracteres referentes às túberas, como cor da casca e da polpa, foram os mais relevantes para a distinção dos acessos. Os resultados obtidos poderão colaborar para elaborar estratégias de conservação, tanto ex situ como in situ, dentro da visão de conservação on farm.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Universidade Federal do Maranhão, Centro de Ciências Agrárias e AmbientaisUniversidade do Sagrado Coração, Central de Laboratórios de Pesquisa, Ciência e Tecnologia AmbientalUniversidade Federal de Santa Catarina, Departamento de Ecologia e ZoologiaUniversidade de São Paulo, Departamento de Genética, Escola Superior de Agricultura Luiz de QueirozUniversidade Estadual Paulista, Departamento de Horticultura, Faculdade de Ciências Agronômicas de BotucatuFAPESP: 2007/04805-2Int Inst EcologyUniversidade Federal do Maranhão (UFMA)Universidade do Sagrado Coração (USC)Universidade Estadual Paulista (Unesp)Universidade Federal de Santa Catarina (UFSC)Universidade de São Paulo (USP)Nascimento, Wellington Ferreira doSiqueira, Marcos Vinícius Bohrer MonteiroFerreira, Almecina Balbino [UNESP]Ming, Lin Chau [UNESP]Peroni, NivaldoVeasey, Elizabeth Ann2015-10-21T20:41:33Z2015-10-21T20:41:33Z2015-03-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article104-113application/pdfhttp://www.scielo.br/scielo.php?script=sci_arttext&pid=S1519-69842015000100015&lng=en&nrm=iso&tlng=enBrazilian Journal Of Biology.
