Morfoanatomia dos órgãos vegetativos de Smilax polyantha Griseb. (Smilacaceae) Rev. Bras. Bot.
Martins,Aline Redondo; Appezzato-da-Glória,Beatriz.
Smilax polyantha Griseb., conhecida como salsaparrilha, é uma espécie reconhecida como medicinal, encontrada em áreas de cerrado, especialmente na região Sudeste. O objetivo desse estudo foi descrever a morfoanatomia dos órgãos vegetativos de Smilax polyantha e verificar se os caracteres descritos na Farmacopéia Brasileira de fato permitem diferenciar esta das demais espécies denominadas salsaparrilha. Amostras dos órgãos vegetativos foram preparadas segundo técnicas usuais em microscopia de luz e eletrônica de varredura. A folha é hipoestomática e os estômatos são paracíticos. O mesofilo tende a dorsiventral, pois o parênquima adaxial é constituído por células com sinuosidades pronunciadas. O pecíolo é canaliculado, sulcado na porção abaxial, indicando...

Propagation studies in Smilax fluminensis Steud. (Smilacaceae) Ciência Rural
Soares,Anielca Nascimento; Novembre,Ana Dionísia da Luz Coelho; Martins,Aline Redondo; Piedade,Sônia Maria de Stefano; Appezzato-da-Glória,Beatriz.
Smilax L. species, popularly known in Brazil as salsaparrilha, have been used in folk medicine as tonic against rheumatism and as anti-syphilitic since the sixteenth century; however, until today, their roots have been explored in an extractive way. The aim of this study was to analyze the propagation of Smilax fluminensis aiming to meet the demand and to propose procedures for its sustainable management. It was analyzed the percentage of seed germination, rooting of aerial and subterranean stem cuttings and plant resprouting capacity after removal of the shoots. The monitoring lasted one year. Seeds were subjected to temperatures: 25°C, 30°C, 20-30°C and 20-35°C under a daily photoperiod of eight hours and in the absence of light. For rooting the stem...

Seed germination and seedling morphology of Smilax polyantha (Smilacaceae) Biota Neotropica
Martins,Aline Redondo; Pütz,Norbert; Novembre,Ana Dionisia da Luz Coelho; Piedade,Sônia Maria de Stefano; Glória,Beatriz Appezzato da.
Brazilians have been using the underground organs of Smilax species in alternative medicine since the 19th century because of their anti-rheumatic qualities. However, even nowadays, these species are explored only by extractivism. Studies on seed germination and development of these organs could be useful to preserve these plants. After germination, seedling development of Smilax polyantha was analyzed to understand underground stem formation. Furthermore, to analyze the ontogenesis of the underground system, seedlings aged from one to twelve months were sectioned. One of the most striking features of this species is the presence of two stem branching systems. The plumule gives rise to the first stem branching system with negative geotropism. Its first...

To resist or to germinate? The effect of fire on legume seeds in Brazilian subtropical grasslands Acta Botanica
Fidelis,Alessandra; Daibes,Luís Felipe; Martins,Aline Redondo.
Fire plays an important role in several grassland ecosystems in the world. Fire can trigger germination in several species, by breaking the physical dormancy of their seeds. Thus, we hypothesized that exposure to high temperatures during fire would break seed dormancy and enhance germination. We tested the effect of high temperatures on the germination of six species of legumes from Brazilian subtropical grasslands. We used heat shock experiments with the following treatments: 60, 90, 120 and 150ºC for one minute. Seeds were then placed to germinate for 60 days in 12/12 hours light/dark and 20/30ºC. Germination was generally low for all study species. Most species was not affected by heat shock treatments. However, Stylosanthes montevidensis was the only...
