Resumo: | http://dx.doi.org/10.5902/198050989294The present study aimed to describe the wood anatomy of Phyllanthus sellowianus Müll. Arg.(Phyllanthaceae), as well as the research of anatomical characters associated with the flexibility of their stems, desirable characteristic for bioengineering works. Belonging to the group of reophyllous and with up to three meters in height, the species occurs naturally in the south of Brazil, Uruguay and Argentina. The exsicat and wood sample from a P. sellowianus, located in the municipality of Santa Maria, Rio Grande do Sul state, Brazi, were deposited in the University Federal de Santa Maria under the numbers HDCF 5587 e 5588. Standard technique was used to set the histological lamina of wood. For macerations used the method of Jeffrey. The Wood anatomy description followed the IAWA Committee (1989). The microscopic analysis revealed the presence vassels of small diameter (< 60µm), radial multiples of 2 to 4 units, and simple perforation plates, obliquely, axial parenchyma absent, heterogeneous rays, with 1-3 cells large, and gelatinous fibers. The absence of axial parenchyma and laticifer tubes is compatible to the Phyllanthaceae group. The presence of perforated ray cells is, probably, the main anatomic component for differentiation of P. sellowianus from the other species of the genera. The abundant presence of gelatinous fibers certainly is one of the main anatomical characteristics related to the high flexibility of its stem. |

Arg. (Phyllanthaceae), bem como investigar caracteres anatômicos associados à flexibilidade de seus caules, característica desejável para obras de bioengenharia em taludes fluviais. Pertencente ao grupo das reófilas, e com até 3 metros de altura, a espécie ocorre naturalmente no sul do Brasil, Uruguai e Argentina. As exsicatas e as amostras de madeira, provenientes de um exemplar localizado no município de Santa Maria-RS (Brasil), foram acondicionadas no Herbário e Xiloteca da Universidade Federal de Santa Maria, sob os números HDCF 5587 e 5588. Para a confecção das lâminas histológicas de madeira, seguiu-se a técnica padrão. Para a maceração, utilizou-se o método de Jeffrey. A descrição anatômica da madeira seguiu as recomendações do IAWA Committee (1989). A análise microscópica do lenho revelou a presença de poros com pequeno diâmetro (< 60 μm), dispostos em múltiplos radiais de 2 – 4 unidades, e de placas de perfuração simples, oblíquas; parênquima axial ausente, raios heterogêneos, com 1 – 3 células de largura, e fibras gelatinosas. A ausência de parênquima axial e de tubos laticíferos é compatível com o grupo das Phyllanthaceae. A presença de células perfuradas de raio constitui-se, possivelmente, no principal elemento anatômico para a diferenciação de P. sellowianus em relação às demais espécies do gênero. A presença abundante de fibras gelatinosas é seguramente uma das principais características anatômicas relacionadas à elevada flexibilidade de seu caule.Universidade Federal de Santa Maria2013-06-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/929410.5902/198050989294Ciência Florestal; Vol. 23 No. 2 (2013); 503-509Ciência Florestal; v. 23 n. 2 (2013); 503-5091980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/9294/pdfDenardi, LucianoTrevisan, RômuloPerrando, Edison RogérioSutili, Fabrício JacquesBaldin, TalitaMarchiori, José Newton Cardosoinfo:eu-repo/semantics/openAccess2017-04-17T18:02:56Zoai:ojs.pkp.sfu.ca:article/9294Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-17T18:02:56Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
