Genetic diversity among natural populations of Mandevilla velutina Horticultura Brasileira
Bertoni,Bianca Waléria; Souza,Ana Valéria de; Biondo,Ronaldo; França,Suzelei de C; Telles,Mariana PC; Pereira,Ana Maria S.
Mandevilla velutina (Mart. Ex Stadelm) Woodson (Apocynaceae) is an endemic species in the Cerrado (Brazilian Savannah), whose alcoholic extracts and root infusions are extensively used in the popular medicine to treat inflammatory diseases and against snake bites. Currently, this species has been pointed out as crucial in conservation programs. Therefore, studies on its genetic diversity, as well as the development of methodology for in vitro conservation in germplasm banks are imperative to avoid its extinction. The objective of this work was to investigate the intra- and inter-populational genetic variability of M. velutina to enhance the representativeness of germplasm banks. To this aim, we used RAPD molecular markers. The analysis of molecular...

Micropropagation, seed propagation and germplasm bank of Mandevilla velutina (Mart.) Woodson Scientia Agricola
Biondo,Ronaldo; Souza,Ana Valéria; Bertoni,Bianca Waléria; Soares,Andreimar Martins; França,Suzelei Castro; Pereira,Ana Maria Soares.
Mandevilla velutina (Mart.) Woodson (Apocynaceae) is a medicinal plant species with antivenom properties, native from Brazilian Savanna regions (Cerrado), which due to overexploitation and habitat deforestation is in danger of extinction. As an initiative for conserving this endangered but economically important plant species, a micropropagation protocol was developed and genotypes were stored in the Germplasm Bank "Cerrado In vitro". For the in vitro propagation of M. velutina, nodal segments were inoculated on Murashige and Skoog (MS) medium supplemented with different concentrations of BA, Zeatin, 2ip, DTT and TDZ. Best multiplication ratio was achieved when to the medium 0.44 µM BA, ranging 1: 6.7, were added. Plantlets cultured on MS/2 medium...
