“…Despite the evident beauty of N. variegata flower stems, whose inflorescence has reddish scape (CMYK 10-100-50-0) measuring approximately 50 cm in height with small flowers of reddish chalice and lilac corolla (CMYK 80-100-30-0), this species is still little studied and explored for its potential ornamental (CAVALCANTE et al, 2017). This specie is commonly known by the Brazilian Northeastern population as "caroá" and is more approached in the academic environment owing to its leaves used in fiber extraction (PAULA and GUARÇONI, 2007;ALMEIDA et al, 2008;SILVEIRA et al, 2009;SILVEIRA et al, 2013). The inflorescences stems are emitted in the transition period between the end of the drought season and the beginning of the rainy season (PEREIRA and QUIRINO, 2008).…”

The Caatinga biome which presents a singular vegetation found only in Brazil has a diversity of vegetal species with uses not yet explored. In this sense, the objective was to study two species of the Caatinga biome to be used as cut flowers. The work was developed at the Agricultural Sciences Campus of the Federal University of the São Francisco Valley, Petrolina, PE. Based on previous studies, two endemic species of the Caatinga biome were selected: Neoglaziovia variegata and Senna martiana. The evaluation criteria were based on the length, stiffness and appearance of the stems; form of flower, fruit or leaf; income in floral composition; color or brightness; scent; originality; and real life in water and floral foam. For these characteristics grades were assigned (0, 5 and 10) and after classified for ornamental potential (high, medium, low and minimum ornamental potential). The results showed that the species N. variegata and S. martiana reached 80 and 85 points, respectively, classifying them as high ornamental potentiality. As such, they can be used as cut flower. Keywords: Neoglaziovia variegata, Senna martiana, floral art, floriculture, semiarid. RESUMOInovação na floricultura com plantas ornamentais do Bioma Caatinga O Bioma Caatinga, que apresenta uma vegetação singular, encontrada apenas no Brasil, possui diversidade de espécies vegetais com usos ainda não explorados. Nesse sentido, objetivou-se estudar espécies da flora da Caatinga para serem utilizadas como flores de corte. O trabalho foi desenvolvido no Campus de Ciências Agrárias da Universidade Federal do Vale do São Francisco, Petrolina, PE. Baseado em estudos prévios foram selecionadas duas espécies endêmicas do Bioma Caatinga: Neoglaziovia variegata e Senna martiana. Os critérios de avaliação foram baseados no comprimento, rigidez e aparência das hastes; forma da flor, fruto ou folha; rendimento na composição floral; cor ou brilho; aroma; originalidade; e, vida útil real na água e espuma floral. Para estas características foram atribuídas notas (0, 5 e 10) e, posteriomente, classificadas quanto ao potencial ornamental (alta, média, baixa e mínima potencialidade ornamental). Pelos resultados obtidos, a espécie N. variegata e S. martiana obtiveram 80 e 85 pontos respectivamente, classificando-as como de alta potencialidade ornamental. Sendo assim, podem ser utilizadas como flor de corte. Palavras-chave: Neoglaziovia variegata, Senna martiana, arte floral, floricultura, semiárido.

“…In spite of its socioeconomic importance it is a poorly studied species, used as a forage source during extended droughts. Its fibers are used by the textile industry, by handcraft workers, and also as a source of polymeric compounds (Silveira et al 2013) The fifteen plots and surrounding strips of variable width were clear-cut in December 2007 (white spaces in Fig. 2).…”

“…Thus, for sustainable utilization and to counter the over-exploitation and consequent threats to biodiversity, it should be envisioned to practice for mass multiplication and conservation of this valuable medicinal plant. In recent years, there has been an increased interest in in vitro culture techniques, which offer a viable tool for mass multiplication and germplasm conservation of rare, endangered and threatened medicinal plants (Radmann et al 2011;da Silva et al 2012;Ouyang et al 2012;Silveira et al 2013). Somatic embryogenesis has been proved to be useful and efficient method for mass clonal propagation of selected material, production of mutants and artificial seeds, genetic engineering and germplasm cryopreservation (Gonzalez-Arnao et al 2008;Hasbullah et al 2013).…”

In this work, plant regeneration via somatic embryogenesis was achieved from leaf and internode derived callus of Wedelia calendulacea, an endangered medicinal plant. Primary callus was induced by culturing leaf disc and internode explant on Murashige and Skoog medium supplemented with 2.0 mg L-1 of 2,4-D under light condition. Transfer of embryogenic callus on a reduced concentration of 2,4-D facilitated somatic embryo development while calluses remained unorganized at the same 2,4-D level. A histological analysis confirmed somatic embryo by revealing the presence of a closed vascular system in the developing embryos and lack of a vascular connection with surrounding callus tissues. Somatic embryos germinated into plantlets upon transfer on MS medium containing 1.0 mg L-1 BAP plus 0.5 mg L-1 GA 3. Plantlets were acclimatized successfully and survived under soil condition. This is the first on somatic embryogenesis of W. calendulacea. This result could facilitate genetic transformation of this important medicinal plant.
