Soil salinization is one of the most important factors impacting plant productivity. About 3.6 billion world's 5.2 ha agricultural dryland have already suffered erosion, degradation and salinization. Halophytes typically are considered as plants able to complete their life cycle in environments where salt concentration 200 mM NaCl or higher. Different strategies known overcome stress, adaptation mechanisms from this type plants. Salinity adjustment a complex phenomenon characterized by both...
Abstract One of the major problems worldwide is soil pollution by trace metal elements, which limits plant productivity and threatens human health. In this work, we have studied effect different concentrations cadmium on Cucurbita pepo plants, evaluating physiological biochemical parameters: hormone signaling, metabolite concentration (malondialdehyde hydrogen peroxide) and, in addition, antioxidant enzyme activities catalase superoxide dismutase were evaluated. The production biomass...
Abstract Barium (Ba) is a nonessential element that can cause several deleterious effects in most organisms. Elevated Ba concentrations be toxic for plants and may affect growth disturbances homeostasis. This study aimed to evaluate the stress, plant‐tolerance limits, detoxification strategy adopted by Cucumis sativus L. The effect of on seed's germination vegetative development this species was evaluated. For test, different were used (0, 200, 500, 1,000, 2,000 μM). Results showed...
Trace metal elements (TMEs) are among the most important types of pollutants in environment. Therefore, a precise determination these contaminants several environmental components is required for safety assurance living organisms. Spectroscopic analysis an efficient technique employed to detect and determine TME contents numerous samples. Hence, achieve reliable accurate results when using spectroscopic analysis, samples should be carefully prepared. In present study, comparison eight...
As a major sink, estuarine/salt marsh ecosystem can receive discharges laden with myriads of contaminants including metals/metalloids from man-made activities. Two among the consequences metal/metalloid-exposure in flora such as halophytic plants are: (a) excessive accumulation light energy that turn leads to severe impairments photosystem II (PS II), and (b) metal/metalloids-accrued elevation reactive oxygen species (ROS) cells causes imbalance cellular redox homeostasis. On one hand, adopt...
The continuous progress of global manufacturing and anthropogenic activities has resulted in excessive environmental metallic pollution, particularly with rare earth elements (REEs) which have become a prevalent issue concern due to their high toxicity widespread existence. REEs-contaminated soils could ruin agriculture by inducing plant physiology disturbances various crops that are considered the principal link human food chain. main purpose present work is assess phytotoxicity two light...
Rare earth elements (REEs) present a group of nonessential metals for the growth and development plants. At high concentrations, they can induce internal stress disturb physiological biochemical mechanisms in The potential uptake lanthanum (La) cerium (Ce) by horticultural plant Helianthus annuus effect these on its growth, absorption macroelements, contents phenolic compounds flavonoids were assessed. plants exposed to 0, 1, 2.5, 5, 10 µM La Ce 14 days. results showed remarkable...
An experiment in this study was designed to investigate the effect of different concentrations Zn2+ or Pb2+ (0, 200, 400 and 600 μM) with NaCl 200 mM), on morphological physiological parameters as well antioxidative response halophytic species Atriplex halimus. Results showed that had no significant impact biomass production while significantly affected plant development mainly at high concentration, μM. Total chlorophyll content did not change under elevation when compared control. However,...
Soil contamination by toxic trace metal elements, like barium (Ba), may stimulate various undesirable changes in the metabolic activity of plants. The plant responses are fast and with, direct or indirect, generation reactive oxygen species (ROS). To cope with stress imposed ROS production, plants developed a dual cellular system composed enzymatic non-enzymatic players that convert ROS, their by-products, into stable nontoxic molecules. assess Ba response two Brassicaceae (Brassica juncea,...
Trace metal element (TME) pollution is a major threat to plants, animals and humans. Agricultural products contaminated with metals may pose health risks for people; therefore, international standards have been established by the FAO/WHO ensure food safety as well possibility of crop production in soils. This study aimed assess accumulating potential aluminum barium roots, shoots fruits Abelmoschus esculentus L., their effect on growth mineral nutrition. The content proline some secondary...
The question of trace metal elements (TME) is still relevant and causes several environmental problems. Moreover, the digestion methods TME have a significant impact on ecosystems. Sample preparation an important step any analytical procedure. In fact, defining levels in vegetal tissues requires various steps: drying samples, crushing, extraction, dosage. use chemical extraction solutions can be put into question. Other than their lack specificity, they are susceptible to provoking...
The objective of the present work was to evaluate extent Cd- and Cu-induced oxidative stress antioxidant response triggered in halophyte species Atriplex halimus after metallic trace elements exposure. Plants were treated for one month with Cd2+ or Cu2+ (400 µM) absence presence 200 mM NaCl irrigation solution. interaction between salinity heavy metal analyzed relation plant growth, tissue ion contents (Na+, K+ Mg2+), damage antioxidative metabolism. Data indicate that shoot root weight...
Abstract Aluminum (Al) is an ubiquitously present element in soil; it considered as a major problem crop production that affects plant growth and development on acid soils. The aim of this work was to determine the germination parameters, quantify water status growth, assess Al accumulation, antioxidant enzyme activities plants evaluate stress exerted by aluminum Cucumis sativus L. For test, increasing doses were used (0, 200, 500, 1,000, 2,000 μM). Results showed stimulated with 500 Al....
The impact of trace metal elements (TMEs) on plants is one current pollution problem, the severity which increasing with industrial development, population growth and inappropriate agricultural practices. latter can have irreversible effects ecosystems, including species extinction, trophic chain contamination altered human health, particularly in case consumed such as zucchini squash (Cucurbita pepo L.). This study aims to investigate nickel various physiological biochemical parameters...
