Plant Phenotyping, Plant Phenotype
Plant phenotyping is the comprehensive assessment of plant complex traits such as growth, development, tolerance, resistance, architecture, physiology, ecology, yield, and the basic measurement of individual quantitative parameters that form the basis for the more complex traits. Examples for such direct measurement parameters are image-based projected leaf area, chlorophyll fluorescence, stem diameter, plant height/width, compactness, stress pigment concentration, tip burn, internode length, colour, leaf angle, leaf rolling, leaf elongation, seed number, seed size, tiller number, flowering time, germination time etc.
After all, plant phenotyping has been performed by farmers and above all breeders for the last seven or more thousand years, essentially since the days humans started to carefully select grasses to increase yield or enhance other desirable traits. In the past, phenotyping was mostly based on experience and intuition, in a process where measurement and interpretation were not separated. This highly integrated approach compensated for the human deficiencies in performing reproducible, objective measurements and dealt with the individual subjectivity factor of the phenotyping person.
A large set of different aspects led to the development of the ever-increasing new field of highly automated, non-destructive plant phenotyping.
LemnaTec scanalyzer plant phenotyping provides a maximum of data for individual plants concerning development, water use, architecture, shapes and reflectance at a wide range of wavelengths, from visible light to heat imaging.

Incentives for automated, non-destructive plant phenotyping with LemnaTec scanalyzer technologies:
- Plant Phenotyping - The need to generate more quantitative data for genetic analysis (QTL, MAS, SMART breeding) and modelling of plant development.
- The requirement to integrate more researchers into the worldwide, interconnected breeding and trait validation process.
- The recognition that information far beyond the direct perception of the human senses (gathered by X-ray, Fluorescence, IR, spectroscopy, terahertz etc.) can contribute efficiently to phenotype description.
- The development of information and data storage technologies, providing suitable tools for the analysis of complex structures like plants.
- The need to accelerate breeding.
- The impossibility for individual breeders and senior research experts to acquire all important data themselves, in order to keep in control of subjectivity effects.
- The urgency to quantify more complex traits.
- The necessity to spot increasingly smaller differences.
- The urgent search for breakthroughs in dealing with the eminent global challenges of climate change and a rising need for more agricultural products.
LemnaTec scanalyzer systems provide these automated and largely image-based, non-destructive plant phenotyping technologies as an integrated system. Depending on the kind of research, customisable systems are available, based on the scanalyzerPL, scanalyzerHTS or scanalyzer3D concept.
