Cd-tolerance markers of Pfaffia glomerata (Spreng.) Pedersen plants: Anatomical...
Pedrosa Gomes, Marcelo; Marques, Teresa Cristina Lara Lanza Sá Sáe Melo; Martins, Giordane Augusto; Carneiro, Marília Mércia Lima CarvalhoPhysiological and anatomical features of Cd-tolerance in Pfaffia glomerata were examined by exposing plantlets to nutrient solutions with increasing Cd concentrations (0, 15, 45, and 90 μmol Cd L-1), and possible Cd-tolerance markers were established. Cd contents were found to be higher in roots than in shoots. According to the bio-concentration factor data, this species is effectively a Cd-hyperaccumulator, as...
Plant physiological ecology and the global changes
Barbosa, J. P.R.A.D.; Rambal, Serge; Soares, Ângela Maria; Mouillot, Florent; Nogueira, Joana Messias Pereira; Martins, Giordane AugustoThe global changes are marked by alteration on the normal patterns of important biochemical and biophysical processes of the Earth. However, the real effects as well as the feedbacks of the global changes over vegetation are still unclear. Part of this uncertainty can be attributed to the inattention of stakeholders and scientists towards vegetation and its complex interrelations with the environment, which dri...
Efeitos dos rejeitos da indústria de zinco na anatomia e crescimento de plantas...
Gomes, Marcelo Pedrosa; Marques, Teresa Cristina Lara Lanza de Sá e Melo; Nogueira, Mariana de Oliveira Gonçalves; Silva, Guilherme HenriqueA poluição por metais pesados, gerada principalmente pelas atividades de mineração e industrial, exige estudos que possibilitem a recuperação de áreas contaminadas. Foram estudadas respostas de crescimento e características anatômicas de plantas jovens de salgueiro cultivadas em solo multicontaminado por metais pesados. As plantas foram cultivadas em três níveis de misturas de solo contaminado: 0%; 15% e 30% (v...
Crescimento, teor de óleo essencial e conteúdo de cumarina de plantas jovens de...
Souza, Girlene Santos; Pinto, José Eduardo Brasil Pereira; Resende, Maria Gorette; Bertolucci, Suzan Kelly Vilela; Soares, Ângela MariaMikania glomerata Sprengel é uma planta medicinal, largamente empregada na medicina popular, utilizada principalmente no tratamento de afecções respiratórias, que age dilatando os brônquios, sendo a cumarina espécie e as suas respostas às condições do ambiente tornam-se necessários ao aperfeiçoamento dos métodos de cultivo. Nesse contexto, o objetivo deste trabalho foi avaliar o efeito do controle do espectro l...
A dinâmica hidrológica na bacia do alto curso do rio Uberabinha - Minas Gerais
Soares, Ângela MariaThis present research fetched the understanding of the landscape´s dynamic, on the basin upper course of Uberabinha river, emphasizing the water resources. The main aim of this research was to understand the superficial and subsuperficial water dynamic and its relation with the use and soil´s occupation. It´s possible that the superficial and subsuperficial water dynamics have changed because of the intense use...

Souza, Girlene Santos; Pinto, Josè Eduardo Brasil Pereira; Resende, Maria Gorette; Bertolucci, Suzan Kelly Vilela; Soares, Ângela MariaMikania glomerata Sprengel é uma planta medicinal, largamente empregada na medicina popular, utilizada principalmente no tratamento de afecções respiratórias, que age dilatando os brônquios, sendo a cumarina uma das substâncias associadas a esse efeito. Por isso, entendimento do comportamento fisiológico dessa espécie e as suas respostas às condições do ambiente tornam-se necessários ao aperfeiçoamento dos méto...
Field performance of vegetative and seed propagated plants of coffee (Coffea ar...
Carvalho, Mychelle; Jesus, Adriana Madeira Santos; Carvalho, Samuel Pereira de; Gomes, Carlos Nick; Soares, Ângela MariaCutting is an alternative method for vegetative propagation of Coffea arabica L. hybrids for commercial purpose. However, the use of such method requires the understanding of the plant growth characteristics under filed conditions. Thus, the objective of the present study was to evaluate and compare the vegetative growth and first yield of Coffea arabica cv. Acaiá plants obtained by cuttings and with see...
Comparison among rooting systems of Coffea arabica L. plants obtained by cuttin...
Jesus, Adriana Madeira Santos; Carvalho, Samuel Pereira de; Soares, Ângela MariaVegetative propagation or cloning of F1 hybrids represents an economy of time and resources for Coffea arabica L. breeding programs. Nevertheless, not much is known about the rooting system of coffee plants propagated by cuttings. An essay was carried out aiming to evaluate Coffea arabica rooting system of plants obtained by vegetative and seedling propagation. Cuttins of the Acaiá and Rubi cultivar with...
