Anatomia Foliar e Caulinar de Picrolemma sprucei Hook (Simaroubaceae)
Anatomical studies of the leaves and stems of Picrolemma sprucei revealed that the epidermes of the leaves are glabrous, with undulating cell walls and anomocytic stomata. The mesophyll is dorsiventral with a layer of cells in palisade and a spongy parenchyma. The vascular bundles are bicollateral a...

Os estudos anatômicos das folhas e caules de Picrolemma sprucei revelaram que as epidermes das folhas são glabras, apresentam células de paredes onduladas e estômatos anomocíticos. O mesofilo é dorsiventral com uma camada de células em paliçada e um parênquima lacunoso. Os feixes vasculares são bicolaterais e apresentam idioblastos escuros de conteúdo tânico. No caule evidencia-se um parênquima cortical desenvolvido, com células de natureza esclerenquimática, isoladas ou reunidas em pequenos grupos, de paredes espessas. Internamente observa-se a região vascular com vasos xilemáticos isolados ou em grupos imersos em tecido fibroso, sendo o parênquima do tipo paratraqueal, vasicêntrico. Na região central encontra-se uma medula desenvolvida. Testes histoquímicos (sudam III e cloreto férrico) realizados na nervura mediana do terço médio do limbo foliar e no pecíolo revelaram respectivamente, a presença de um conteúdo tânico e óleo-resinoso em algumas de suas células. 2020-04-24T15:28:12Z 2020-04-24T15:28:12Z 2003 Artigo https://repositorio.inpa.gov.br/handle/1/13516 10.1590/1809-4392200332220 pt_BR Volume 33, Número 2, Pags. 213-220 Attribution-NonCommercial-NoDerivs 3.0 Brazil http://creativecommons.org/licenses/by-nc-nd/3.0/br/ application/pdf Acta Amazonica |
