HyperRoot provides hyperspectral images in the range between 1000 – 1700 nm with a 5 nm spectral resolution and a 0.1 mm spatial resolution. The rhizoboxes used for HyperRoot have a size of 1000 x 300 mm and thus allow for imaging mature plant root systems. The infrastructure is mainly intended for early phenotyping tasks related to root ecophysiology such as (i) investigating spectral features in root-soil systems encoding for biochemical characteristics (e.g., root senescence, water content of soil and root tissues), (ii) quantify water depletion around roots via water absorption bands, and (iii) spectral band detection for root-soil features for informing high-throughput multispectral root phenotyping pipelines. HyperRoot thus represents a scientific phenotyping infrastructure for hypothesis-driven root research and requires knowledge in processing hyperspectral imaging data.
