Estudo morfo-anatômico da folha e do caule de Piper arboreum Aubl. (Piperaceae)

Abstract

Piper L. inclui grande número de espécies de interesse medicinal. Piper arboreum Aubl. é frequente em matas de Maringá, Paraná, cujas folhas e caule são analisados morfológica e anatomicamente. O material botânico dessa espécie foi seccionado à mão livre, transversal e longitudinalmente, e corado com azul de astra e safranina. O pecíolo e base da nervura central apresentam 15-20 feixes vasculares. A lâmina foliar é hipostomática, dorsiventral e mostra complexo estomático estaurocítico, subepiderme e idioblastos oleíferos. O caule possui feixes vasculares medulares e não se observa endoderme típica como ocorre em outras espécies de Piper.

The genus Piper L. includes a great number of medicinal interest species. P. arboreum is frequent in forests of Maringá, Paraná State, Brazil. Its leaves and stem are analyzed morphologic and anatomically, freehand sectioned in cross-section and longitudinal section, and were stained in astra blue and safranin. Petiole and midrib base present 15-20 vascular bundles. The blade is hypostomatic, dorsiventral and shows staurocytic stomatal complex, subepidermis and oil idioblasts. The stem possesses medullary vascular bundles; a typical endodermis is not observed, as it occurs in other Piper species.
