The information whether a substance has toxic effects to plants is essential in various application cases. This comprises wanted toxicity of candidate herbicidal substances as well as the exclusion of toxicity for any substances that accidentally come in contact with plants in the environment. A standard procedure for testing such toxicity is the duckweed test, which is well established in many laboratories. It is used for many applications including environmental monitoring, in product development, or for assessment of water quality.
Beyond LemnaTec’s imaging and image processing tools for duckweed analysis, other image processing procedures can serve to address toxic effects. This can comprise measuring movements or feeding of insects, mites, or other small organisms, or the phenotypic analysis of plant stress responses, e.g. in response to soil salinity or soil contamination.
