1. The management of orthotropic stems modulates the photosynthetic performance and biomass allocation of productive plants of Arabica coffee
ABSTRACT Due to the possibility of enhancing the physiological responses by modulating the architecture of coffee trees, the objective of the study was to analyze the leaf gas exchanges and biomass allocation of Arabica coffee cultivated with different numbers of orthotropic stems. The experiment was carried out in a plantation located in Santa Teresa-ES, Br

2. Improvement in light utilization and shoot growth in Hymenaea stigonocarpa under high CO 2 concentration attenuates simulated leaf herbivory effects
ABSTRACT This study evaluated the photochemical responses of photosystem II and growth of Hymenaea stigonocarpa under CO2-enriched conditions with exposure to simulated herbivory events. After herbivory simulation in two distinct parts of the stem of plants (apex and base), chlorophyll a fluorescence, chlorophyll index, growth, extrafloral nectary density, l

3. Management Of Commelina benghalensis with Saflufenacil in Shaded Environments
RESUMO: O uso repetitivo de glyphosate no controle de plantas daninhas em plantios de eucalipto tem selecionado espécies tolerantes a esse herbicida, como a Commelina benghalensis. Diante disso, torna-se necessária a aplicação de herbicidas de outros mecanismos de ação, como o saflufenacil, em rotação ou em mistura com o glyphosate, para reduzir os d

4. Efeito do sistema de plantio e da exposição solar sobre a alocação da biomassa no desenvolvimento inicial do eucalipto
Resumo Este trabalho foi desenvolvido com o objetivo de comparar a alocação da biomassa arbórea, a conicidade do tronco e a relação altura e diâmetro ao longo do fuste de árvores de eucalipto implantadas em um sistema silvipastoril, em diferente exposição solar, e em monocultivo. Os dados foram coletados em 13 árvores-amostra aos 27 meses de idade,

6. Tolerance to and Accumulation of Cadmium, Copper, and Zinc by Cupriavidus necator
ABSTRACT Preliminary results of in vitro experiments with multicontaminated soils and solid media indicated that nodulating diazotrophic bacteria of the genus Cupriavidus are promising for the remediation of contaminated environments due to their symbiosis with legumes and metal tolerance. Thus, strains of Cupriavidus spp. (LMG 19424T, UFLA 01-659, UFLA 01-6

7. Combined effects of low light and water stress on Jatropha curcas L. promotes shoot growth and morphological adjustment
Jatropha curcas (physic nut) is a plant with economic and pharmaceutical uses. Basic studies on the influence of environmental factors on the early development of J. curcas are important for improving farming techniques and increasing productivity. This study investigated the adjustments of J. curcas to the environmental factors of drought and light stress i

8. Effect of water stress on seedling growth in two species with different abundances: the importance of Stress Resistance Syndrome in seasonally dry tropical forest
ABSTRACTIn seasonally dry tropical forests, species carrying attributes of Stress Resistance Syndrome (SRS) may have ecological advantages over species demanding high quantities of resources. In such forests, Poincianella bracteosa is abundant, while Libidibia ferrea has low abundance; therefore, we hypothesized that P. bracteosa has characteristics of low-r

9. Modeling the microbial growth of two Escherichia coli strains in a multi-substrate environment
The microbial growth in multi-substrate environments may be viewed as an optimal resources allocation problem. The optimization aims at maximizing some biological objective like the biomass growth. The models developed using this hypothesis are called "cybernetic" and they represent the complex cell structure as an optimizing function that regulates the intr

10. Input of sugarcane post-harvest residues into the soil
Sugarcane (Saccharum spp.) crops provide carbon (C) for soil through straw and root system decomposition. Recently, however, sugarcane producers are considering straw to be removed for electricity or second generation ethanol production. To elucidate the role of straw and root system on the carbon supply into the soil, the biomass inputs from sugarcane straw

11. Modificações morfológicas e metabólicas em gramínea e leguminosa forrageiras tropicais relativas ao suprimento de enxofre / Metabolic and morphological changes in grass and legume tropical forages related to sulfur supply
O enxofre é um dos elementos essenciais para as plantas e as exigências nutricionais nesse nutriente variam com a espécie e a taxa de crescimento das plantas. Com o objetivo geral de avaliar o efeito da nutrição em enxofre no crescimento e no metabolismo do capimtanzânia (Panicum maximum cv. Tanzânia) e do estilosante (Stylosanthes guianensis cv. Mine
