(Cyperaceae) Santos, Pedro Paulo dos Potiguara, Raimunda Conceição de Vilhena Priprioca Cyperaceae monocotiledônea Cyperus articulatus L. CNPQ::CIENCIAS BIOLOGICAS::BOTANICA::MORFOLOGIA VEGETAL::ANATOMIA VEGETAL Cyperus articulatus L., known as priprioca, cultivated in the State of Pará for the extraction of essential oil from its underground system, is used in the confection of cosmetics. Considering the importance of this species, a morpho-anatomical study was proposed, aiming to support taxonomic and pharmacognostic studies. The botanical material was collected in the experiment at Belem, from the community of Boa Vista, Acará. In the laboratory, the vegetative organs were measured and fixed for anatomical study. The morphological study identified: a 79 in - 1.6 m x 3 - 8 mm cylindrical stem; a 5 - 8 cm x 5 - 7 mm cylindrical stoloniferous rhizome interrupted by 1 - 3 in diameter spherical tubercles, from which 3 - 8 in long tuberous roots originate; 14 - 27 x 1 - 2 cm aciculate and sessile basal leaves. In the anatomy of these organs, in cross section, the root, rhizome and tuber are divided into lining, cortical and vascular regions. However, the root presents these structurally distinct regions, which are: lining of irregular cells; cortex with 3 forms of parenchyma, fibers and endodermis; and vascular region with pericycle, sclerenchyma and vascular elements there the rhizome and tuber are lined by rectangular cells; cortex with sclerenchyma, endodermis and parenchyma, where the oil cells occur; and the vascular region with parenchyma and amphivasal vascular elements. The thatch is lined by irregular epidermal cells, some siliceous; and the rest of the organ by parenchyma with the vascular elements. The hypostomatous leaf is covered on both surfaces by tabular epidermal cells and siliceous cells, the mesophyll consists of parenchyma cells, aerenchyma and vascular elements. Through the results obtained, it is concluded that the rhizome and tuber are the most suitable organs for the extraction of essential oil, which scientifically supports the popular use of the underground system. Cyperus articulatus L., conhecida como priprioca, cultivada no Estado do Pará para a extração de óleo essencial do seu sistema subterrâneo, é usada na confecção de cosméticos. Diante da importância dessa espécie, foi proposto realizar o estudo morfo - anatômico da mesma, visando subsidiar trabalhos taxonômicos e farmacognóstico. O material botânico foi coletado no experimento da uma - Belém, procedente da comunidade de Boa Vista, Acará. Em laboratório, os órgãos vegetativos foram mensurados e fixados para estudo anatômico. Na morfológico identificou-se: colmo cilíndrico de 79 em - 1,6 m x 3 - 8 mm; rizoma estolonífero cilíndrico de 5 - 8 cm x 5 - 7 mm, interrompido por tubérculos esféricos de 1 - 3 em de diâmetro, de onde se originam raízes tuberosas de 3 - 8 em de comprimento; folhas basais aciculadas e sésseis de 14 - 27 x 1 - 2 cm. Na anatomia desses órgãos, em corte transversal, a raiz, o rizoma e o tubérculo dividem-se em regiões de revestimento, cortical e vascular. Entretanto, a raiz apresenta essas regiões estruturalmente distintas, que são: revestimento de células irregulares; córtex com 3 formas de parênquima, fibras e endoderme; e região vascular com periciclo, esclerênquima e elementos vasculares lá o rízorna e o tubérculo são revestidos por células retangulares; córtex com esclerênquima, endoderme e parênquima, onde ocorrem as células oleíferas; e a região vascular com parênquima e elementos vasculares anfivasais. O colmo é revestido por células epidérmicas irregulares, algumas silicosas; e o restante do órgão por parênquimas com os elementos vasculares. A folha hípostomátíca é revestida em ambas superfícies por células epidérmicas tabulares e células silicosas, o mesofilo é constituído por células parenquimáticas, aerênquimas e elementos vasculares. Através dos resultados obtidos, conclui-se que o rizoma e o tubérculo, são os órgãos mais adequados à extração de óleo essencial, o que respalda, cientificamente, a utilização popular do sistema subterrâneo. 2023-04-28T16:08:06Z 2023-04-28 2023-04-28T16:08:06Z 2004-07-01 Resumo SANTOS, Pedro Paulo dos; POTIGUARA, Raimunda Conceição de Vilhena.
