Abstract:
As the access to genotypic data has increasingly become inexpensive, the need for quantitative phenotypic data to complement this information becomes more imminent. The phenotyping facilities at Purdue University: The Indiana Corn and Soybean Innovation Center (ICSC) and The Controlled Environment Phenotyping Facility (CEPF) provide scientists a unique opportunity to leverage machine vision and other advanced sensing technologies in assessing complex plant traits.The ICSC facilitates the development of ground-based and UAV-based approximal sensing platforms for high-throughput assessment and quantification of key crop traits, such as crop cover, crop height, biomass estimation etc. The CEPF is featured with a costumer-designed growth chamber and a fully automated fertigation/irrigation system. These system provide the capability to accommodate growing plants up to three meters tall. When it comes time for measurements, the plants in the chamber are carried by an automated conveyor belt system to an RGB camera system which acquires color images of the plants and extract key parameters such as color, size, morphological traits, and number of leaves, length of each leaf, etc of each plant. The plants can also be transferred to a hyperspectral camera system which provides spectral information in the Visible and Near-infrared (VNIR) as well as shortwave infrared (SWIR): 400 – 25,00 nm waveband. The HSI cameras can be used to detect chemical composition of plants to determine relative water content of leaves, nutrient composition, as well as vegetation indices, herbicide damage, and foliar pathogen progression. The CT-Xray system in the CEPF offers the opportunity in non-destructive measurements on root morphology and root architecture. The Zegami Plant Phenomics Suite is leveraged to facilitate visualization of the acquired data. Research carried out in the CEPF can provide insights that bridge the gap to help explain gene function, provide insight in nutrient use efficiency, and how water stresses impact plant growth.
