Resumo: The objective of this work was to evaluate qualitative and quantitative leaf anatomical traits of Palicourea rigida Kunth. (Rubiaceae) species occurring in the Brazilian Cerrado and Campo Rupestre ecosystems. Anatomical analysis was performed in fresh or fixed leaves processed with usual plant microtechnique. Leaves showed uniseriate epidermis in petiole and leaf blade which contains uniseriate nonglandular tricomes (tector type) occurring only over the vascular bundles. Likewise, paracytic stomata were found only in abaxial side of the leaf surface. The mesophyll contains uniseriate palisade parenchyma and multiseriate spongy parenchyma (nine layers) which showed cells with different morphology and size. Crystal idoblasts of different types were observed in both the petiole and leaf blade. Collateral vascular bundles were found both in the petiole and leaf blade. Leaf venation type was pinnate, campylodromous or brochydodromous. The micromorphometric analysis showed significant differences from plants of different environments for all leaf characteristics and Cerrado plants showed higher means for all evaluated traits. Therefore, the influence of environments may had modulated morphological responses in P. rigida, since no difference was found in the type or distribution of leaf tissues in Cerrado or Campo Rupestre.

(Rubiaceae), espécie que ocorre em áreas de cerrado e campo rupestre. As observações anatômicas foram realizadas em folhas de material fresco ou fixado, tratadas segundo metodologias usuais em anatomia vegetal. Foram observadas as seguintes características: epidermes do pecíolo e da lâmina foliar uniestratificadas; presença de tricomas tectores, simples, unisseriados, próximos, ou sobre as nervuras; estômatos do tipo paracítico presentes somente na face abaxial da folha; mesofilo com parênquima paliçádico de uma só camada de células; parênquima esponjoso com sete a nove camadas celulares com formas irregulares e tamanhos variados; idioblastos cristalíferos, observados em todos os parênquimas do pecíolo e lâmina foliar; feixes vasculares, do tipo colateral; colênquima observado, subepidermicamente, no pecíolo e nervuras de maior porte, em ambas faces; o padrão geral de nervação da espécie é pinado, camptódromo, broquidódromo. As análises micromorfométricas revelaram diferenças significativas em todos os itens analisados, sendo as médias mais elevadas encontradas nas folhas das plantas crescendo no cerrado. Isto sugere que a influência de fatores ambientais pode ter modulado respostas morfológicas nas plantas, visto que o tipo e distribuição dos tecidos não sofreram alterações nos dois ambientes.CERNE2016-06-082017-08-01T20:15:10Z2017-08-01T20:15:10Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttp://www.cerne.ufla.br/site/index.php/CERNE/article/view/1201GAVILANES, M.
