Investigating the floral and reproductive biology of the endangered microendemi...
Teixeira, Valber Dias; Verola, Christiano Franco; Costa, Itayguara Ribeiro da; Zappi, Daniela C.; Costa, Grênivel Mota da; Silva, Suelma RibeiroThe Cactaceae are known to be amongst the most endangered plant families of the world due to reduction of their habitats and activities of collectors. As the species of the family are dependent on animals to perform cross pollination, and hence seed production, their population performance may be further negatively affected by interrupted biotic interactions. For efficient conservation of rare species, knowledg...
Comparative seed germination, morphology and post-seminal development of two Br...
Rocha, Moema Angélica Chaves da; Souza, Everton Hilo de; Soares, Taliane Leila; Souza, Fernanda Vidigal Duarte; Alfaya, Maria Cristina FerreiraKnowledge about the behavior of seeds is important to support studies to minimize the effects of predatory extractivism on ornamental bromeliads. The aim of this study was to evaluate the germination, seed morphology and post-seminal development of Hohenbergia belemii and Neoregelia compacta (Bromeliaceae) in different substrates. Seeds were disinfested with a sodium hypochlorite solution and germinated in four...
Micropropagation and in vitro conservation of Alcantarea nahoumii (Bromeliaceae...
Silva, Simone Sacramento dos Santos; Souza, Everton Hilo de; Souza, Fernanda Vidigal Duarte; Nepomuceno, Cristina FerreiraAlcantarea nahoumii (Leme) J. R. Grant is a species native to the Atlantic Forest that stands out for ornamental purposes. The objective of this work was to evaluate the in vitro germination of A. nahoumii seeds and establish a micropropagation protocol for production of seedlings so as to minimize the effects of predatory extractivism and develop an in vitro conservation system. Mature seeds were disinfested, ...
Leaf geometric morphometrics among populations of Dalbergia ecastaphyllum (L.) ...
Morais, Daniel Vieira de; Nunes, Lorena Andrade; Mata, Vandira Pereira da; Costa, Maria Angélica Pereira de Carvalho; Sodré, Geni da SilvaLeaves are plant structures that express important traits of the environment where they live. Leaf description has allowed identification of plant species as well as investigation of abiotic factors effects on their development, such as gases, light, temperature, and herbivory. This study described populations of Dalbergia ecastaphyllum through leaf geometric morphometrics in Brazil. We evaluated 200 leaves fro...
Dalbergia ecastaphyllum leaf extracts: in vitro inhibitory potential against en...
Morais, Daniel Vieira de; Moreira, Manuela Maria; Silva, Fabiane de Lima; Costa, Maria Angélica Pereira de Carvalho; Delerue-Mato, CristinaFor the first time, the anti-hemolytic activity and the enzyme inhibitory activities of Dalbergia ecastaphyllum leaves extracts were tested against α-amylase, α-glucosidase, lipase, acetylcholinesterase, butyrylcholinesterase, tyrosinase and hyaluronidase. The phenolic profile of the obtained extracts was also investigated by high-performance liquid chromatography with photodiode array detection (HPLC-PAD). The...
Antioxidant, photoprotective and inhibitory activity of tyrosinase in extracts ...
Morais, Daniel Vieira de; Costa, Maria Angélica Pereira de Carvalho; Santa Bárbara, Marivalda Figueredo; Silva, Fabiane de Lima; Moreira, Manuela M.Dalbergia ecastaphyllum is a native Brazil plant with importance for beekeeping, and widely used in folk medicine. For the first time, the extracts of this plant were assessed for the presence of hydrophilic and lipophilic antioxidants, as well as inhibition of tyrosinase, free radicals scavenging and sunscreen protection. The antioxidant activity was evaluated by free radical scavenging (DPPH) and β-carotene b...
