Resumo: | The anatomy of rhizomes and roots of 14 species of Bromeliaceae that occur in the cerrado biome were studied with the aim of pointing out particular anatomical features of the family and possible adaptations related to the environment. All the rhizomes are similar although some have root regions growing inside the cortex. In some species the vascular cylinder of the rhizome is clearly limited from the cortex. The roots are also very similar, although the coating tissue differs in roots growing inside the rhizome or externally to it and the cortex has a variable organization according to the region. The studied species present anatomical features that are associated to water absorption and storage, showing that they are adapted to the cerrado environment. |

Os rizomas apresentam estrutura básica semelhante, embora alguns deles possuam porções radiculares crescendo no interior de seu córtex. De acordo com a espécie considerada, os rizomas podem apresentar um cilindro vascular de delimitação mais ou menos nítida. As raízes também possuem estrutura básica semelhante, apesar do tecido de revestimento variar de acordo com a porção analisada (dentro do rizoma ou externa). Além disso, as raízes apresentam uma região cortical de organização variada, de acordo com a região do órgão, e um cilindro vascular. Muitos dos caracteres anatômicos observados estão associados a mecanismos de captação e retenção hídrica, mostrando que as espécies estudadas estão adaptadas ao ambiente de cerrado.Universidade Estadual Paulista, Instituto de BiociênciasUniversidade Estadual Paulista, Instituto de BiociênciasInstituto de Pesquisas Jardim Botânico do Rio de JaneiroUniversidade Estadual Paulista (Unesp)Proença, Suzana Lúcia [UNESP]Sajo, Maria Das Graças [UNESP]2021-07-14T10:54:12Z2021-07-14T10:54:12Z2008info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article113-128application/pdfhttp://dx.doi.org/10.1590/2175-7860200859106Rodriguésia.
