New publication in Nature Machine Intelligence

Paper in Nature Machine Intelligence published We proudly present our recent publication resulting from our DePhenSe project together with Rheinische Friedrich-Wilhelms-Universität Bonn, TU Darmstadt, and Institut Für Zuckerrübenforschung "Making deep neural networks right for the right scientific reasons by interacting with their explanations" on machine learning for hyperspectral [...]

Added value in seed germination testing

Added value in seed germination testing Rice germination dynamics of five cultivars – LemnaTec SeedAIxpert case study. When testing germination of crop seeds, the intended use is the main driver for setting criteria to call a seed batch a “good” one. When sowing the [...]

Fruit phenotyping with LemnaTec multi-camera imaging and image processing.

Fruit phenotyping with LemnaTec multi-camera imaging and image processing. In tobacco plants, fruit capsule color indicates the maturity of the contained seeds. With progressing maturity, color changes from green over yellow to brown. When harvesting seeds, it is desired to have same levels of maturity and thus surface [...]

Plant Performance

Plant Performance Digital phenotyping delivers diverse parameters that describe the phenotypic appearance of a plant. In combination with time-course data, which indicate how the parameters change over time, such datasets give a holistic view on how a plant performs. The performance is not only the growth, but growth [...]

Petri dish growth assays – documenting and phenotyping

A common practice in laboratory tests, e.g. when studying functions of mutations, is growing seedlings on solid media in petri dishes. Such growth assays serve to compare phenotypic properties of mutants and wild types in an easy and fast manner. The phenotypic differences between mutants and wild types are [...]

The advantage of digital phenotyping in environmental stress assessment

The advantage of digital phenotyping in environmental stress assessment Abiotic stresses have large potential of damaging plants, and this is one of the major threats in crop production. Detecting and quantifying stress effects gives a strong advantage in rating plant performance and stress tolerance. Digital [...]

Brassica heat and drought phenotyping

A LemnaTec Scanalyzer at work: Environmental stresses frequently occur in combination, particularly the combination of high temperatures and low water availability is common during hot weather. Such stresses negatively affect plant growth and reproduction. In Brassica crops such stresses impair pod setting and filling and research is done to strengthen [...]

Glutathione, growth, and water deficit

LemnaTec's Chief Scientist Dr. Marcus Jansen has co-authored a paper on phenotyping studies to evaluate potential links between Glutathione, growth, and sensitivity to low water availability in Arabidopsis. Before joining LemnaTec in 2014, Marcus was working at Forschungszentrum Jülich and participated in a project on water deficit responses that [...]

Desert tomato plants grow at minimal water availability

Wild relatives of crops frequently are more resistant to environmental stress factors than modern crop cultivars. Therefore, wild relatives might be sources of genes that improve stress tolerance or resistance. A wild tomato species Solanum pennellii originating from desert environments has thick leaves and copes well with water limitation. [...]

Extending Hyperspectral Imaging for Plant Phenotyping to the UV-Range

Hyperspectral imaging is a powerful tool in phyisological phenotyping. In particular, assessments of plant disease can benefit from spectral imaging, and frequently non-visible wavelengths provide additional information to the spectral signatures derived from visible light. Together with our partners in the DePhenSe project we recently published a paper in [...]

Phenomics-Assisted Breeding with LemnaTec Scanalyzer

As climate change makes conditions for agriculture more adverse, plant breeding must speed up and deliver better adapted plants. Phenomics-assisted breeding can shift QTL detection to earlier stages of plant development so that breeding decisions can take place faster. The LemnaTec Scanalyzers can deliver phenomic data on young plants [...]

Gravimetric determination of water use with LemnaTec Scanalyzer

LemnaTec Conveyor Scanalyzers do imaging and image processing delivers traits such as digital biomass, but a further function is the high precision weighing and watering of the plants in the system. In a study on water use efficiency of Setaria plants, researchers at the Donald Danforth Plant Science Center [...]

Phenotyping for heat-resilient tomato plants

Heat stress tolerating crops are highly desirable to enable better farming in tropical and subtropical areas and to better cope with climate change effects. Analysing gene functions in heat stress responses, researchers used a LemnaTec Scanalyzer for biovolume and colour determination of tomato plants under elevated temperatures. The digital [...]

Phytotoxicity Test in the Development of Ecofriendly Pesticides

In the current debate on pesticides causing environmental damage, the search for ecofriendly pesticides is gaining importance. Plants frequently contain compounds that counteract fungi or other plants; thus, such substances might be used in agriculture. However, it is important to rule out potential dangers before applying them in practical [...]

NIR Imaging for Water Potential Monitoring in Perennial Plants

Drought affects the water potential in the plant tissues. When water limitation reduces the water potential, many physiological processes become impaired and thus slow down or even stop. Monitoring water potential by non-invasive measures is an important tool for detecting stress induced by water limitation. NIR imaging can serve [...]

LemnaTec LabScanalyzer supports breeding for climate-resilient beans.

Beans are a key protein source for large parts of the world population, but bean plant cultivation is threatened by adverse climatic conditions. Breeding aims at improving future bean varieties for better yield performance under environmental stress. Researchers at the Mexican Colegio de Postgraduados Institute applied a LemnaTec LabScanalyzer [...]

Phenotyping for improved biomass

When growing plants for bio-energy, it is highly desirable to avoid any competition with food production and to minimise any energy-demanding agricultural management such as fertilisation. Thus, ideally such plants grow on marginal land without adding fertiliser and without irrigation. The discrepancy between low resource availability and maximised biomass production [...]
