As orquídeas por apresentarem características florais que chamam a atenção quanto a cor, aroma e textura, são muito valorizadas comercialmente, sendo considerado um dos grupos de plantas com maior potencial de comercialização. O aprimoramento de técnicas de propagação e cultivo aliado à utilização de novas espécies e variedades têm impulsionado o mercado de orquídeas. Em decorrência, grande incremento no comércio destas plantas tem sido observado dentro e fora do Brasil. O presente estudo aborda as possibilidades de uso das espécies de orquídeas do Estado do Amapá e suas potencialidades para o desenvolvimento econômico regional. Os dados desta pesquisa foram compilados e analisados no período de agosto a outubro de 2015, com base na lista das Orchidaceae do Amapá, depositadas no Herbário Amapaense (HAMAB). Foram registradas trinta e cinco espécies de orquídeas que apresentam algum tipo potencial de uso, a forma de vida, a distribuição geográfica, a utilidade, o valor médio de comercialização e a imagem. Palavras chave: Diversidade, flora orquídica, importância econômica The economic potential of orchids in Amapá state ABSTRACT. Orchids for presenting floral characteristics that draw attention to color, aroma and texture, are highly valued commercially, being considered one of the groups of plants with greater marketing potential. The improvement of propagation and cultivation techniques allied to the use of new species and varieties have driven the orchid market. As a result, a large increase in the trade of these plants has been observed in and outside Brazil. This study addresses the possibilities for the use of the orchid species of the state of Amapá and its potential for regional economic development. The data of this survey were compiled and analyzed in the period from August to October 2015, based on the list of the Orchidaceae of Amapá, deposited in the Herbarium Amapaense (HAMAB). Thirty-five species of orchids were registred that present some kind of potential use, the Life form, the geographical distribution, the utility, the marketing value and the image.
RESUMO -Este trabalho apresenta as variações morfológicas no labelo da flor de Catasetum barbatum (Lindl.) Lindl. em material oriundo de comunidades naturais na Amazônia legal e no Brasil Central. Foram reconhecidas 16 variações em 4 habitats diferentes, provavelmente relacionadas com mudanças nas características ecológicas do meio. São apresentadas ainda distribuição geográfica e ilustrações das variações do labelo. Palavras-chaves:Variações, Catasetum barbatum, labelo. Morphological Variations of the Flower Lip of Catasetum barbatum (Lindl.) Lindl. (Orchidaceae)ABSTRACT -This paper presents a study of morphological variation, of the lip of the flowes of Catasetum barbatum (Lindl.) Lindl., basead on plants collected in Brazillian Amazonia and Central Brazil. Sixteen variations in 4 different habitats were recognized and related to the
Natural hybridization has often been recorded within certain genera of orchids, one of them is Catasetum. During a field study in a forest de igapó in Brazilian Amazon, a new natural hybrid was found, it is here described as Catasetum × sheyllae. Its morphological features, mainly the structures of the lip, are intermediate between those of its putative parent species, C. boyi and C. garnettianum, both observed in sympatry.
