Growth rate based dose-response relationships and EC-values of ten heavy metals using the duckweed growth inhibition test (ISO 20079) with Lemna minor L. clone St.
The duckweed Lemna minor L. clone St was used to investigate the effect of 10 heavy metals under the standardised test conditions of the ISO protocol 20079. By using growth rates derived from frondExpand

Phytotoxicity of cobalt ions on the duckweed Lemna minor - Morphology, ion uptake, and starch accumulation.
Cobalt (Co2+) inhibits vegetative growth of Lemna minor gradually from 1 μM to 100 μM. Fronds accumulated up to 21 mg Co2+ g(-1) dry weight at 10 μM external Co2+ indicating hyperaccumulation.Expand

Induction of frond abscission by metals and other toxic compounds in Lemna minor.
Fronds of the duckweed Lemna minor L. clone St form colonies of different sizes on the basis of stipes connecting mother and daughter fronds for some time after the development of daughter fronds.Expand

High-Throughput Plant Phenotyping – Data Acquisition, Transformation, and Analysis
The aim of applied plant biology has always been to understand how and why plants grow the way they do. In most cases, the target of research is to find correlations and dependencies between distinctExpand

Ozonation of pyrene and benzo[a]pyrene in silica and soil –14C-mass balances and chemical analysis of oxidation products as a first step to ecotoxicological evaluation
Ozonation of polycyclic aromatic hydrocarbons (PAHs) in soil is a process that can be used for in-situ soil remediation or in combination with bioremediation techniques. First steps to aExpand

Sensitivity of Different Growth Inhibition Tests–Just a Question of Mathematical Calculation? Theory and Practice for Algae and Duckweed
Hazard assessment often needs to compare inhibition values of different test species and different test durations. But the three different methods to calculate inhibition in growth inhibition testsExpand

A novel mechanism of abscission in fronds of Lemna minor L. and the effect of silver ions.
Lemna minor L. (duckweed) forms colonies through vegetative propagation because mother fronds remain connected for some time with their daughter fronds by stipes. The colony size is controlled byExpand
