Resumo: Three hundred and fourty umbu trees (Spondias tuberosa A. Câm.) were characterized in 17 ecogeographic regions distributed in seven States of Northeast Brazil. The Agroecological Zoning of the Northeast and the information about extractivism of fruits of umbu tree were used to define the regions of sample. Twenty umbu trees were characterized in every ecogeographic region for 11 quantitative characters. The techniques utilized for all information were: principal components of correlations matrix and cluster analysis using the euclidian distance of the original standardized data and the nearest centroid sorting method. The trees were grouped in 17 clusters independently of the region of origin, evidencing that edafoclimatic difference and geographic distance did not interfere in the evolution and differentiation of umbu trees. The ecogeographic regions of Tanquinho, Jeremoabo and Ipupiara, Bahia State; Petrolina, Pernambuco State; and Pio IX, Piaui State, are indicated as points of dispersion or origin of umbu tree. Weight of fruit, diameter of canopy, diameter of fruit, weight of fruit peel and height of plant were the characters of less importance for discrimination of umbu tree.

Câm.) em 17 regiões ecogeográficas, distribuídas em sete estados do polígono da seca. As áreas de amostragens foram definidas com base nos dados de extrativismo da espécie e no zoneamento agroecológico do Nordeste. Em cada ecorregião, foram avaliadas, ao acaso, 20 árvores quanto a 11 caracteres quantitativos. Os dados foram submetidos às seguintes análises: componentes principais, a partir da matriz de correlação e análise de agrupamento pelo método "nearest centroid sorting", adotando a distância euclidiana como medida de dissimilaridade, com os dados originais padronizados. As árvores foram agrupadas em 17 grupos, independentemente da região de origem, sugerindo que as diferenças edafoclimáticas e as distâncias geográficas não interferiram de forma marcante na evolução e na diferenciação do umbuzeiro. As ecorregiões de Tanquinho, Jeremoabo e Ipupiara, BA; Petrolina, PE; e Pio IX, PI, por apresentarem mais de 40% de indivíduos similares (dentro do grupo), são indicadas como regiões de dispersão e/ou especiação do umbuzeiro. Os caracteres peso do fruto, maior diâmetro da copa, diâmetro do fruto, peso da casca do fruto e altura da planta foram os de menor importância para discriminação das árvores avaliadas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSantos, Carlos Antonio Fernandes1997-09-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4729Pesquisa Agropecuaria Brasileira; v.32, n.9, set. 1997; 923-930Pesquisa Agropecuária Brasileira; v.32, n.9, set. 1997; 923-9301678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4729/7302info:eu-repo/semantics/openAccess2015-03-18T20:53:33Zoai:ojs.seer.sct.embrapa.br:article/4729Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2015-03-18T20:53:33Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
