With the rapid development of high-throughput plant phenotypic measurement technology, more and more researchers and breeders are beginning to adopt this emerging technology for research.
The era of plant phenotypes has arrived! Plant phenotypes is an interdisciplinary field of research that must be combined with genomics, bioinformatics, and big data computing to better serve breeding.
A survey conducted by the International Plant Phenotype Organization (IPPN), the European Plant Species Organization (EPPN) and the German Plant Phenotype Organization (DPPN) showed field phenotypes, data management, costs, root phenotypes, abiotics Stress, industry standards, technical limitations, bioinformatics, flux, etc. are the main problems that constrain the development of plant phenotypes.
Among them, Field Phenotyping is recognized as the biggest challenge in plant phenotypic research and plant phenotypic development!
The world's first truly commercial high-throughput plant field phenotyping platform was the FieldScan system ( video link ) that was officially launched at the International Semi-Arid Crop Research Institute (ICRISAT) in India in early 2014.
The FieldScan system of the Crop Research Institute of the International Semi-Arid Region of India is equipped with eight PlantEye sensors for fully automated high-throughput measurements in the 16 mx 200 m range. The platform is currently measuring 10 times a day and has been in continuous operation for more than two years.
Europe's leading plant and microbiology research center, the John Innes Center in the UK, the Jenkins Center (JIC), also has a FieldScan system ( video link ) for high-throughput plant phenotypic platforms. Unlike the Indian International Semi-Arid Crop Research Institute, which focuses on field plants, the FieldScan system at the John Innes Center is a high-throughput phenotypic measurement of crops grown in natural soils.
Max Planck Society and Molecular Plant Physiology of the system will be a small FieldScan mounted to the greenhouse, for high-throughput measurement potato plant phenotype.
About the FieldScan System
The FieldScan system is a phenotypic platform designed by the well-known Dutch PhenoSpex company for high-throughput plant phenotypic measurements in the field, and can be measured 24/7 under any environmental conditions.
FieldScan is designed with the plant laser 3D scanning instrument PlantEye as the core and integrates a variety of other sensors. PlantEye is used to obtain plant growth. Through the top imaging of 3D, not only the leaf area, leaf inclination angle, canopy and other parameters can be obtained, but also higher precision and throughput than other technologies can be obtained. Of course, other sensors can be integrated when needed. ( video link )
In any light situation, FieldScan can perform 10 repeated measurements on tens of thousands of plants (depending on the size of the system) every day without affecting the growth of the plant itself, providing users with valuable data to understand the plant. The growth of the field.
FieldScan not only scans plants grown in the field, but also scans potted plants. When using potted plants, the transpiration rate can be calculated by tracking the weight of each plant according to a pressure sensor.
Design Concept - Finding a Balance between High Throughput and Accuracy <br>In modern plant research and breeding, field phenotype is one of the most urgent areas for phenotypic grouping and has been facing various challenges. For example, from full sunlight to nighttime, the extreme changes in temperature and rainfall and other external environments not only affect the measurement technology, but also have a great impact on plants. Therefore, for measurement technology, it is necessary to set a very reasonable signal-to-noise ratio to accurately obtain phenotypic information. At the same time, it is necessary to obtain high-throughput phenotypic information of plants in a limited period of time; Synchronous monitoring is also necessary.
When developing FieldScan, our goal was to provide a field phenotypic acquisition system that could be used in any environment; multiple scans per day; and low quality data. If we focus on throughput and flexibility, we can use mobile devices such as tractors or UAVs in the field. But in order to achieve high-precision measurements in millimeters, we decided not to use these traditional mobile devices, and high-precision measurements are only available for stationary systems. To do this, we need to develop a mobile platform that can meet both high precision and high throughput.
Suitable for both greenhouses and fields
Since the FieldScan system has been able to adapt to the harsh field environment, it is of course possible to perform high-throughput measurements in the greenhouse. We have installed several systems in the greenhouse for different customers, and like the field system, we have achieved excellent measurement results.
