Abstract:<p>O mercado de plantas ornamentais busca por inovação e variedades bem adaptadas, porém a maioria das plantas ornamentais cultivadas no Brasil é exótica, as quais nem sempre são bem adaptadas. Stenachaenium megapotamicum é um subarbusto com alto potencial ornamental e ocorrência espontânea nos Campos Sulinos. Nesta pesquisa, avaliou-se o potencial paisagístico, potencial como flor de corte e adaptabilidade em diferentes condições de cultivo. A pesquisa foi conduzida entre os meses de junho de 2010 e mai… Show more
“…Native plants with ornamental potential have been the subject of research in various parts of the world, showing a tendency to look for new species for landscaping (Cavalcante et al, 2017). These can be more adapted to the conditions of the regions where they are naturally found, than exotic plants (Noya & Cuquel, 2013). The commercial production of native plants legally regulated by Brazilian legislation, in accordance with the rules of the National System for the Management of Genetic Heritage -SISGEN, can be an important tool for ex situ conservation, through direct contribution to the dissemination, valorization and preservation of local biodiversity, but also for environmental education, with the spread of the regional landscape identity (Silva & Perelló, 2010;Brasil, 2015;Stumpf et al, 2015).…”
The flora of the ferruginous Campo rupestre that occur over the immense iron deposits of the Carajás National Forest is very unique, with several endemic and rare species. This vegetation is directly affected by mining activity, as a result of vegetation suppression and the profound disfigurement of habitats. The objective of this work was to identify the ornamental potential of the flora of the ferruginous Campo rupestre, as a strategy for ex situ conservation of ecosystem species. The species present in ten plots of 5 x 5 m were surveyed in different areas of the ferruginous Campo rupestre on the N1 plateau and the ornamental potential of each species was evaluated following a characterization key, considering morphology and habitat of occurrence. Subsequently, the species were compared with those already present on the market, as ornamental, based on the literature and on sites specialized in the sale of ornamental plants in Brazil. A total of 33 species with ornamental potential were found, distributed in 32 genera and 19 families. Most species showed high functionality for ornamentation and similarity with nationally consolidated ornamentals. Catasetum planiceps, Cyrtopodium andersonii, Epidendrum nocturnum, Mandevilla scabra, Norantea guianensis and Sobralia liliastrum have a consolidated ornamental market. The data collected support ex situ conservation strategies of the flora of the ferruginous Campo rupestre, such as its valorization, local commercialization and income generation for small extractivists in the region.
