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 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 [...]
Duckweed (Lemna sp.) is an indicator organism in ecotoxicology. Image processing for phenotypic classification of duckweed was the very first application case for LemnaTec and is mirrored in our name. Read here how it works.
In plant pathology, rating of disease symptoms is a frequent task to assess disease severity and thus determine e.g. the resistance level of a genotype or the efficiency of a plant protection agent. Symptom rating can comprise symptom counting, in particular if the disease symptoms appear a single spots [...]
Plant growth processes are complex, and many regulators take influence to ensure that the growth adequately follows the plant’s genomic program as well as the given environmental circumstances. Leaf growth begins in leaf primordia where cell proliferation takes place. Balanced activity of promoting and repressing factors ensures proper growth [...]
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 [...]
An example of a phenotypic comparison of four Arabidopsis genotypes carried out by Australian researchers is presented here.
Overexpression of RING Domain E3 Ligase ZmXerico1 Confers Drought Tolerance through Regulation of ABA Homeostasis Drought tolerance is one of the key properties of crops in current and future agriculture. For a better understanding of drought tolerance mechanisms, researchers at DuPont Pioneer investigated the ABA signaling pathway, where the [...]
Herbs, also referred to as microgreens, are traditionally used as spices for cooking, and they frequently contain health-promoting substances. When growing them in controlled environments such as greenhouses and particular indoor farms or vertical farms, electrical illumination is required as light source. It is well-known that light not only [...]
LemnaTec scientists Marcus Jansen, Stefan Paulus, Kevin Nagel and Tino Dornbusch published a book chapter in the book “Bioassays” edited by Donat Häder and Gilmar Erzinger. The chapter “Image processing for bioassays” describes the use of a range on non-invasive sensors for measuring phenotypes. It provides insight in processing [...]
