Tolerância ao manganês por bactérias isoladas em área contaminada por rejeito d...
Oliveira, Tayla Évellin de; Andrade, Paula Cristina Castro; Esteves , Gisele de Fátima; Mantovani, José Ricardo; Silva , Adriano Bortolotti daO objetivo deste estudo foi isolar bactérias presentes no rejeito de mineração e avaliar sua tolerância ao metal manganês. O isolamento dos microrganismos foi realizado a partir do rejeito coletado no município de Mariana, Minas Gerais, proveniente da área contaminada por lama de mineração em decorrência do rompimento da barragem de Fundão. Foram obtidos quatro isolados, que foram submetidos aos testes de color...

Banana leaf anatomy characteristics related to ploidy levels
Madail, Rafael Hansen; Pio, Leila Aparecida Sales; Rezende, Renata Alves Lara Silva; Pasqual, Moacir; Silva, Sebastião de Oliveira eMany important crops have cultivars with different ploidy and provide a diverse choice of materials for breeding programs. Therefore, it is essential to accurately assess the ploidy of all breeding materials. Increased DNA content is known to have various effects on external and internal morphology, an effect known as the “nucleotypic effect”. Thus, anatomical assessment can be used as a tool for determining pl...
Fruit quality and harvest point determination in white-fleshed dragon fruit
Rangel Junior, Ivan Marcos; Magalhães, Deniete Soares; Rodrigues, Filipe Almendagna; Pasqual, Moacir; Pio, Leila Aparecida SallesThe objective of this study was to evaluate the quality of white-fleshed dragon fruit (Hylocereus undatus) at harvest and postharvest to determine fruit quality and the feasibility of harvesting the fruits at different outer fruit color stages. The treatments consisted of four peel color stages – S1 (<25% red peel), S2 (25%-49% red peel), S3 (50% to 75% red peel) and S4 (>75% red peel) – and two evaluatio...
Isolation and identification of microorganisms that promote growth and inoculat...
Pereira, Maysa Mathias Alves; Araújo, Ronilson Carlos; Martins, Adalvan Daniel; Rodrigues, Filipe Almendagna; Pasqual, Moacir; Dória, JoyceThe inoculation of growth-promoting bacteria has already shown benefits in different cultures such as increased biomass production for the growth of roots and stems, greater resistance to water stress conditions and changes in their physiological properties. Plant growth promoting bacteria have stood out for their potential application in plant production, allowing the reduction of the use of fertilizers and pe...

Polyploidy induction in Physalis alkekengi
Santos, Gustavo C; Cardoso, Felipe P; Martins, Adalvan Daniel; Rodrigues, Filipe A; Pasqual, Moacir; Cossani, Paulo; Magno Queiroz Luz, JoséPhysalis alkekengi is an ornamental plant that can also be used as a medicinal plant due to its anti-inflammatory, bactericidal, antitumor and fungicidal properties. Polyploidization can be an important tool in the genetic improvement of this species. The objective this work was to obtain tetraploids in vitro and to evaluate the phytotechnical traits of P. alkekengi. For this, nodal segments of P. alkekengi var...
Effect of light and sucrose on photoautotrophic and photomixotrophic micropropa...
Santos, Gustavo C; Cardoso, Felipe P; Martins, Adalvan D; Pasqual, Moacir; Ossani, Paulo C; Queiroz, José Magno; Rezende, Renata A L S; Dória , JoyceThe biotechnological interest in genus Physalis has increased in the last decades, however, there are still few micropropagation studies of this genus. The objective of this study was to evaluate P. angulata photoautotrophic and photomixotrophic micropropagation with gas exchange under seven light spectra and five concentrations of sucrose. Lighting were yellow, blue, white, red, green, red + blue LEDs and natu...
Use of molecular markers SSR and SCAR for identification of olive accessions
Val, Aurinete Daienn Borges do; Breves, Sâmera de Souza; Cançado, Geraldo Magela de Almeida; Ferreira, Juliano Lino; Pasqual, MoacirMorphological and agronomical describers are traditionally used in plant characterization. However, the usage of these describers have some limitations such as susceptibility to abiotic and biotic stress and environmental factors. Furthermore, the describers are not stable over time and many can only be evaluated during the adult phase of the plants, which requires time and physical space. Molecular markers off...
