Resumo: | The objective of this work was to relate the occurrence of macaúba (Acrocomia aculeata (Jacq.) Lodd. ex Martius) in Minas Gerais State, Brazil, to climatic, pedological and vegetation attributes. The State has three huge regions where macaúba occurs: Alto Paranaíba, Zona Metalúrgica, and Montes Claros. The Montes Claros region is relatively warmer and drier than the two others, although these regional macroclimatic differences do not limit the macaúba occurrence. Within those regions, nine soil sequences were selected and sampled in the landscape, totalizing 27 soil profiles, being also registered the primitive vegetation in each case. The use of soil chemical and physical attributes allowed to discriminate the sets of landscape segments (sites) with and without macaúba through the principal components analysis; the correlations with the chemical attributes were the most relevant. The macaúba occurrence followed soil areas where the natural fertility was higher and where the primitive vegetation was forest, showing that the species advances as pioneer, avoiding extreme conditions of deficiencies of nutrients and water. The surveyed data evidence that in all cases the macaúba occurrence only happened when the primitive vegetation is semideciduous forest. |

Lodd. ex Martius) no Estado de Minas Gerais a atributos climáticos, pedológicos e vegetacionais. O Estado possui três grandes regiões de ocorrência de macaúba: Alto Paranaíba, Zona Metalúrgica e Montes Claros. A região de Montes Claros é relativamente mais quente e mais seca do que as outras duas, porém as diferenças macroclimáticas regionais não chegam a representar um fator limitante à ocorrência da macaúba. Dentro de cada região, foram selecionadas e amostradas nove seqüências de solos na paisagem, totalizando 27 perfis de solo, registrando-se, inclusive, a vegetação primitiva. O uso de atributos químicos e físicos do solo permitiu separar de forma eficiente os conjuntos de segmentos da paisagem (sítios) com e sem macaúba, mediante a análise de componentes principais, dos quais as correlações com os atributos químicos são os mais relevantes. A ocorrência de macaúba acompanhou áreas de solos com fertilidade natural mais elevada e vegetação primitiva de fisionomia florestal, o que mostra que a espécie avança como pioneira, evitando extremos de deficiência de nutrientes e de água. Os resultados evidenciam que, nos casos estudados, a ocorrência da macaúba só se verificou quando a vegetação primitiva é de floresta subcaducifólia.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária Brasileirada Motta, Paulo Emílio FerreiraCuri, NiltonFilho, Ary Teixeira de OliveiraGomes, João Bosco Vasconcellos2002-07-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6433Pesquisa Agropecuaria Brasileira; v.37, n.7, jul. 2002; 10123-1031Pesquisa Agropecuária Brasileira; v.37, n.7, jul. 2002; 10123-10311678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6433/3490info:eu-repo/semantics/openAccess2010-08-17T12:35:02Zoai:ojs.seer.sct.embrapa.br:article/6433Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-08-17T12:35:02Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
