“…Compostos fenólicos estão presentes principalmente nas células epidérmicas e muitos cristais de oxalato de cálcio foram encontrados nas folhas e no caule. As funções determinadas para os cristais de oxalato de cálcio são variadas, dentre elas a osmorregulação e o balanço iônico, o armazenamento de cálcio ou oxalato, o suporte mecânico e a proteção contra herbivoria (Duarte & Lopes, 2005).…”

RESUMO:Este trabalho apresenta o estudo morfoanatômico das folhas e caules de Microlicia hatschbachii Wurdack, Melastomataceae. Esta espécie possui folhas elípticas a oval-elípticas, margem inteira, ápice agudo e base simétrica e arredondada. A lâmina foliar é anfiestomática, com estômatos do tipo anisocítico e anomocítico, a epiderme é uniestratificada, com células isodiamétricas em secção transversal, e presença de inúmeros tricomas glandulares. O mesofilo é do tipo isobilateral com feixe vascular bicolateral envolvido por algumas células esclerenquimáticas na nervura central. O caule tem secção quadrangular a circular e epiderme unisseriada, com tricomas similares aos da folha. Drusas de oxalato de cálcio foram encontradas nas folhas e no caule. Unitermos: Microlicia hatschbachii, Melastomataceae, morfoanatomia.ABSTRACT: This work shows the morpho-anatomical study of leaf and stem of Microlicia hatschbachii Wurdack (Melastomataceae). Its leaves are elliptic to oval-elliptic, with entire margin, acute apex and rounded symmetrical base. The leaf blade is amphistomatical with anisocytic and anomocytic stomata, in transection the epidermis is uniseriate with isodiametric cells and presence of several glandular trichomes. The mesophyll is isobilateral with bicollateral vascular bundles surrounded by some sclerenchymatic cells in midrib. The stem has a quadrangular to circular transection and uniseriate epidermis with trichomes like ones of leaf. Several druses of calcium oxalate are found in the leaf and stem.

Medicinal plants are described such as those produce substances capable of provoking reactions in the human body leading to the cure of diseases. Like as cultivated species, medicinal plants can be attacked by various pests and diseases, affecting the qualitative and quantitative characteristics of their curative properties, as well as productivity. Phytonematodes are one of the main factors limiting the productivity of cultivated plants. In medicinal species this pathogens group has caused damage in the sanity of the plants interfering in the quality of the compounds produced. Among them, due to the high parasitism degree, the species of the genus Meloidogyne, popularly known as root-knot nematodes. Among the management strategies of these phytopathogens, biological and cultural controls have low efficiency reports. Likewise, chemical control is not indicated due to its high cost, besides, its high toxicity and risk of environmental pollution. Therefore, the most effective control method is the use of resistant plant species or cultivars. Once these species are identified, they can be used as antagonists or incorporated into the soil, aiming to decrease the nematode population in infested areas. The use of resistant medicinal species allows little or no reproduction of Meloidogyne spp., providing effective control in the field. Other advantages are the reduction of production costs, and the protection of the environment against pollution caused by chemical waste.

En el presente trabajo se presentan los resultados de un estudio sobre tres especies de las cuales se comercializan productos considerados adaptógenos: Lepidium meyenii Walp. (Brassicaceae), "maca", Morinda citrifolia L. (Rubiaceae), "noni", y Petiveria alliacea L. (Phytolaccaceae), "pipi". Los datos provienen de estudios en Etnobotánica urbana realizados en la conurbación Buenos Aires-La Plata, se presentan los usos tradicionales de las especies, sus vías de ingreso, comercialización y difusión como suplementos dietéticos en el contexto pluricultural urbano, los modos actuales de empleo y los saberes relacionados, que forman parte del conocimiento botánico local. De este modo, se evalúan las modificaciones en los usos originalmente asignados, como consecuencia de la expansión de los productos en el marco de la globalización, y los cambios consecuentes en los patrones tradicionales de saberes, creencias y prácticas referidos a estos recursos vegetales
