Fluorine is found in the atmosphere mainly in the form of hydrofluoric acid, released by industries linked to the production of aluminum, glass and ceramics, in addition to phosphate fertilizers. It is an element of high toxicity, quite harmful to plant growth. Eugenia dysenterica (Mart.) DC. (Myrtaceae) species is a fruit tree native to the Brazilian Cerrado with wide distribution in anthropic regions. Thus, the objective of this work was to investigate the potential of E. dysenterica for fluoride ...

Fluoride is released in large amounts in the atmosphere by brick, ceramic, phosphate mineral and aluminum industries. It presents the highest phytotoxicity when compared to other air pollutants, damaging different tree species. Byrsonima basiloba Juss. (Malpighiaceae) is a fruit tree widely distributed in anthropic regions, displaying high potential as a bioindicator. In this context, the aim of the present study was to investigate fluoride effects, by means of simulated rainfall, by evaluating morphological ...

Fluoride is one of the main phytotoxic pollutants released into the atmosphere. It can be released in the form of potassium fluoride by brick, ceramic, phosphate mineral and aluminum industries, causing damage to different plant species. Sapindus saponaria L. (Sapindaceae) is widely distributed throughout Brazil, and has been used both in the recovery of degraded areas and in urban afforestation. In this context, the aim of the present study was to determine S. saponaria bioindicator potential through ...

Native Cerrado plants are exposed to soils with low pH and high availability of Al. In this study, we measured the Al content in adult plants, and investigated the effects of various Al doses on germination and early development of Eugenia dysenterica plants. For germination tests, the seeds were soaked in Al solution and evaluated for twenty days in growth chambers. In a second experiment, young plants were cultivated in hydroponic systems with various Al concentrations to evaluate the morphological, ...

Summary Plants continue to lose water from their leaves even after complete stomatal closure. Although this minimum conductance ( g leaf‐res ) has substantial impacts on strategies of water use and conservation, little is known about the potential drivers underlying the variability of this trait across species. We thus untangled the relative contribution of water leaks from the cuticle and stomata in order to investigate how the variability in leaf morphological and anatomical traits is related to the ...

Aluminum (Al) exposure effects on Hancornia speciosa Gomes were investigated via culture in a nutrient solution containing 0 (control), 300 and 600 μmol Al L−1. Seedling emergence, nutrient accumulation, growth and root anatomy were evaluated. Seedling emergence, emergence speed index and root diameter under hydroponic cultivation were significantly reduced in the Al treatments, while Al promoted root growth at the lowest concentration. Al also altered macronutrient translocation in the analyzed plant ...

Strategies to promote bone repair have included exposure of cells to growth factor (GF) preparations from blood that generally include proteins as part of a complex mixture. This study aimed to evaluate the effects of such a mixture on different parameters of the development of the osteogenic phenotype in vitro. Osteoblastic cells were obtained by enzymatic digestion of human alveolar bone and cultured under standard osteogenic conditions until subconfluence. They were subcultured on Thermanox coverslips ...

ABSTRACT The goal of this research was to examine phytotoxicity and leaf anatomy of pequi plants (Caryocar brasiliense Cambess.) exposed to simulated drift of glyphosate. The experimental design was randomized blocks with nine replications. Each experimental unit was composed by one 18-L pot with one plant. The treatments consisted of different doses of glyphosate sprayed: 0 (control), 50, 100, 250, 500, 1000 and 1500 g ae ha-1 of glyphosate. Phytotoxicity visual ratings were carried out at 7, 14 ...

Ecological contamination by air pollutants is a worldwide problem. Fluoride-based compounds are released in large proportions into the atmosphere, soil and water from various industrial sources. These compounds are more phytotoxic to various plants than are other pollutants. The objective of this work was to determine the effects of fluoride in the form of potassium fluoride (KF)-simulated rain, on morphological and physiological responses, macronutrient content and fluoride accumulation in Spondias ...

Background Fluoride pollution is a global problem because of its high phytotoxicity. Fluoride is released in air, water and soil through industrial processes, where it damages various plant species. Ricinus communis is widely distributed in Brazil, India and China and has been extensively used as a phytoremediation species in heavy metal-contaminated soils. However, few studies regarding the effect of air pollutants on R. communis have been published, and no information about the exposure of this ...

The potential use of n-dodecane as an oxygen vector for enhancement of Crypthecodinium cohnii growth and docosahexaenoic acid (DHA) production was studied. The volumetric fraction of oxygen vector influenced the gas–liquid volumetric mass transfer coefficient k L a positively. The k L a increased almost linearly with the increase of volumetric fraction of n-dodecane up to 1%. The stirring rate showed a higher influence on the k L a than the aeration rate. The effects of this hydrocarbon on C. cohnii ...

Liquid mixing in tall tanks agitated by multiple radial turbines can be modelled by a cascade of well-mixed compartments with backflows. Models have been proposed with different numbers of compartments per stage of agitation. In this paper, the five simplest models are compared in their ability to predict mixing times and concentration transients, and in their requirement for adjusted parameters. Examined models have from 1 to 4 compartments per agitation stage. The model which consists of 3 compartments ...

Abstract A mixing model previously developed for the determination of mixing time in gassed tanks stirred by multiple Rushton turbines (Vasconcelos et al., 1995) was verified for the additional scales of 0.39, 0.56 and 0.72 m vessel diameter. It is now shown that the single adjusted parameter previously required by the model, the air‐induced axial velocity parameter v ax , is scale‐independent with an invariant value of 7 × 10 −2 m/s. Model simulations, with tank and turbine diameters and the number of ...

In this paper, five parameters of a double arrowhead auxetic model were analyzed: mass, critical buckling load, natural frequency, Poisson’s ratio, and maximum load of compression. A Response Surface Methodology was considered and applied together with a new meta-heuristic of optimization called the Multi-Objective Lichtenberg Algorithm to optimize the structural performance of the auxetic model. All the results were obtained from numerical solutions that were validated with experimental tests. ...

Fluoride is one of the main phytotoxic environmental pollutants, and high concentrations (10-30 mg L-1) are commonly detected in surface and groundwater. Little, however, is known about the effects of this pollutant on crops that require irrigation during their development, which, in addition to phytotoxicity, may cause negative human health effects. Thus, the aim of this study was to characterize the effects of potassium fluoride (KF) on the germination of lettuce seeds and identify the physiological ...

ABSTRACT Talinum triangulare (Jacq.) Willd, known as Ceylon spinach, Surinam purslane, or waterleaf, is cultivated for medicinal and food purposes. Among environmental factors, light is an important regulator of primary production, contributing to plant growth. However, the success of each plant species depends on its morphoanatomical responses to light. The aim of this study was to determine whether T. triangulare leaf micromorphometry is affected when grown in full sun and under shade, and if so, ...

Plants are continuously exposed to unfavorable environmental conditions, such as heat stress, which negatively affect plant growth and productivity. There is evidence that phytochromes are involved in plant response to different abiotic stresses. We investigated the possible phytochrome-dependent responses to heat stress in photomorphogenic tomato mutants aurea (au, phytochromobilin-deficient, PΦB) and high-pigment 1 (hp1, hyperresponsive to phytochrome-mediated responses), as well as the wild-type ...
