Case Studies

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 [...]

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 [...]

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 [...]

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 [...]

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 [...]

Using High-Throughput Phenotyping to Explore Growth Responses to Mycorrhizal Fungi and Zinc in Three Plant Species

Mycorrhizas generally are considered as beneficial plant-microbe interactions. Advanced non-invasive phenotyping technology gives insight in the dynamic development of the plants in response to mycorrhiza. Non-invasive assessments of the dynamic development of the digital biomass with a LemnaTec Scanalyzer revealed that mycorrhiza can cause growth depressions. The influence – positive [...]

Plant Phenotyping: Past, Present, and Future

Phenotype analysis is challenging. It‘s even more challenging than genome analysis or other biological or chemical studies. Roland Pieruschka and Uli Schurr, phenotyping experts at Forschungszentrum Jülich back up this statement by considering the complex structure of plants, their fluctuating environments, and memory effects that translate through the plant lifecycles [...]

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 [...]

Digital plant analysis serving in hazard assessment of future fuels

Fossil fuels have limited availability, and - most important - burning them endangers the world's climatic system. Thus, there is an urgent demand for alternate, environment-friendly fuel systems. A lot of energy can be captured using e.g. wind power stations but making this compatible to classical fuel uses is [...]

LemnaTec colour analysis quantifies genotype-phenotype relations

Chloroplast development is a key function in plants and carotenoids carry out regulatory functions in the developmental program. Dissecting the underlying gene functions provides essential knowledge in understanding chloroplasts and thus photosynthesis. Mutants were analysed that correspond to genes with different functions in the regulatory network, and these mutants [...]

Digital phenotyping in developing novel weed control

Weed control is becoming increasingly challenging because many herbicides become banned by authorities or weeds gain resistance against the active ingredients. Alternative methods frequently are labour- or energy- intensive. Exploring allelopathic substances might deliver novel weed control compounds. The duckweed growth inhibition test serves as an indicator whether a [...]

Analysing Seeds

Measuring the components of maize seeds On the surface of maize (Zea mays) seeds, areas of the embryo and the endosperm are visible, and fractions of these parts differ between maize cultivars. In yellow-seeded varieties, endosperm areas are darker-yellow, whereas the embryo areas are light-yellow [...]

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 [...]

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 [...]
