Chlorophyll Fluorescence Phenotyping
Category: Leaf- and Shoot Phenotyping, Physiological Phenotyping, Stress and Disease Phenotyping
Chlorophyll Fluorescence serves as measure for the status and activity of the photosystem II. Analyzing images of chlorophyll fluorescence delivers photosynthesis-related data at whole-plant level. Measurements provide basic and maximum fluorescence of dark (F0, Fm) or light (F, Fm') adapted plants. These factors serve to calculate parameters such as Fv/Fm, NPQ, ETR and more. In phenotyping, such analyses are used to rate the physiological status of plants and to figure out the effects of stress, diseases, or environmental factors.
Vegetation Indices
Category: Leaf- and Shoot Phenotyping, Physiological Phenotyping, Stress and Disease Phenotyping
Vegetation indices can be calculated from multispectral or hyperspectral measurements. A vegetation index is calculated from the spectral reflectance of a plant sample at two or more wavelengths. Such indices serve to characterize developmental or physiological properties of the plants. For instance, greenness indices relate to chlorophyll abundance, pigment-related indices refer to e.g., anthocyanin or carotenoids, or stress-related indices are responsive to biotic and abiotic stress factors. Dozens of indices are reported in the literature, and it is possible to establish customized indices, too.
Arabidopsis Phenotyping
Category: Leaf- and Shoot Phenotyping
Arabidopsis phenotyping aims at measuring phenotypic properties of Arabidopsis shoots, i.e., the rosettes. Typically plants are grown in trays, and individual plants are placed in regular patterns, for instance in rows and columns. The analysis delivers data per plant. Once time series of such trays are taken, growth and development can be monitored. Data comprise rosette area, rosette morphology, e.g., compactness, or surface colors. Arabidopsis phenotyping is carried out in various application ranges in plant science, for instance in studies on gene functions, in plant-environment assessments, or to rate treatment effects.
Seed germination and seedling phenotyping
Category: Leaf- and Shoot Phenotyping, Root Phenotyping, Seed- and Seedling Phenotyping (Seed Testing)
Phenotyping of germinating seedlings comprises assessments of germination tests on moist paper. The core scope is to determinate the germination rate, but measurements on seedling phenotypes, and the temporal development of seedlingd delivers further data. This can be used to rate seedling quality and viability. Seed germination phenotyping is a typical task in seed laboratories, for instance at seed breeding companies, gene banks, or in seed testing facilities.
