Environmental conditions and plant physiology modulate Cu phytotoxicity in field-contaminated soils

open access: yesEcotoxicology and Environmental Safety, 2022
Foliar Cu concentration has been widely used as a biomarker of plant growth in phytotoxicity bioassays. This relation has helped find plant processes altered by Cu in dose-response experiments (a bivariate approach).

Soil Effects on the Bioactivity of Hydroxycoumarins as Plant Allelochemicals

open access: yesPlants, 2023
Soil plays a primary role in the activity of plant allelochemicals in natural and agricultural systems. In this work, we compared the phytotoxicity of three natural hydroxycoumarins (umbelliferone, esculetin, and scopoletin) to different model plant ...

Influence of fine process particles enriched with metals and metalloids on Lactuca sativa L. leaf fatty acid composition following air and/or soil-plant field exposure [PDF]

open access: yes, 2013
We investigate the effect of both foliar and root uptake of a mixture of metal(loid)s on the fatty acid composition of plant leaves. Our objectives are to determine whether both contamination pathways have a similar effect and whether they interact ...

Assessment of Phytotoxicity of Parthenin

open access: yesZeitschrift für Naturforschung C, 2007
Phytotoxicity of parthenin, a sesquiterpene lactone, was evaluated against four weedy species (Amaranthus viridis, Cassia occidentalis, Echinochloa crus-galli, and Phalaris minor) through a series of experiments conducted under laboratory or greenhouse conditions to assess its herbicidal potential.

Phytotoxicity of Tires Evaluated in Simulated Conditions

open access: yes, 2021
Illegal dumps and landfills with disposed of tires are a fact of today, which should not be neglected as they represent a great ecological burden for the environment, affect the surrounding nature and disturb the landscape.

Influence of soil properties and aging on arsenic phytotoxicity

open access: yes, 2006
Bioavailability of As varies among soils, and this needs to be taken into account during environmental risk assessment. Using a standardized barley root elongation assay, we investigated the phytotoxicity of arsenate added to 16 European soils that ...
