Lead tolerance during germination and early growth of the Brazilian peppertree ...
Pereira, Marcio Paulo; Pereira, Fabricio José; Corrêa, Felipe Fogaroli; de Oliveira, Cynthia; de Castro, Evaristo Mauro; Barbosa, SandroWoody plants are important for phytoremediation systems, and few species of lead hyperaccumulators are known. We evaluated the lead (Pb) tolerance of Schinus molle L. plants and the resulting anatomical and physiological modifications during germination and early growth. Two experiments were conducted to evaluate the response of S. molle seeds and plants to exposure to five concentrations of Pb(NO3)2 (0.0, 0....
Mechanisms of the internal structure and operation of Panicum aquaticum in resp...
Pires, Marinês Ferreira; de Castro, Evaristo Mauro; de Oliveira, Cynthia; Pereira, Fabricio José; Pasqual, MoacirDue to the high toxicity of arsenic, many studies have attempted to improve the techniques for its removal from the environment, using methods such as phytoremediation by tolerant species. To evaluate the tolerance of Panicum aquaticum to contamination by arsenic, both physiological and anatomical evaluations were conducted. The plants were grown in Hoagland and Arnon nutrient solution in a greenhouse for 30 ...
Anatomical and physiological characteristics of tanner grass exposed to arsenic
Argenta, João Antônio; de Oliveira, Cynthia; de Castro, Evaristo Mauro; Pires, Marinês Ferreira; Pereira, Fabricio José; Pasqual, MoacirPhytoremediation is a biological process that stands out as an effective and economic alternative for the removal of toxic elements; however, its success depends on previous studies of plant species and the species’ tolerance of certain pollutants. The aim was at evaluating the anatomy and physiology of Tanner grass (Brachiaria arrecta) to determine its anatomical and physiological plasticity characteristics ...
Anatomy of stems, leaves, roots and the embryo of Garcinia brasiliensis Mart. -...
Cardoso, Amanda Ávila; Pereira, Fabricio José; Pereira, Marcio Paulo; Corrêa, Felipe Fogaroli; de Castro, Evaristo Mauro; Santos, Breno RégisStudies concerning the structure of plant embryos are very important in different areas of study such as plant systematics and evolution or the handling of native species. This work aims at evaluating the anatomy of the embryo and vegetative organs of Garcinia brasiliensis in order contribute to taxonomical, ecological, handling studies of this species. Some seeds were stored for anatomical analysis of the em...
Foliar anatomy of coffee plants implanted using hydro retainer polymers
Oliveira, Noêmia Karen; de Castro, Evaristo Mauro; Guimarães, Rubens José; Pieve, Leonardo Miari; Baliza, Danielle Pereira; Machado, Janaíne LopesThe experiment was conducted at the Fazenda Capão dos Olhos, in the municipality of Coqueiral, Minas Gerais, Brazil, in the period of 2009 and 2011. The present work aimed at verifying the changes in the foliar anatomy of coffee plants implanted using hydro retainer polymers. For such, we collected leaves for posterior evaluation of foliar anatomy from plants derived from different treatments (dilutions, doses ...
