Hyperspectral reflectance phenotyping in duckweed accessions shows a predictive ceiling: vegetation indices weakly predict chlorophyll (R2 =0.34) and Fv/Fm (R2 =0.25), while PLSR reaches R2 ≈0.5 for key photoprotective traits.
- Why it matters: Rapid, low-input selection proxies are needed because duckweed accessions vary widely in growth, biomass, pigments, and photosynthetic performance under controlled, ambient-light conditions.
- What they did: The study measured growth, pigment composition, photosynthetic performance, and hyperspectral reflectance across 133 UK accessions from six duckweed species, then tested light-tolerance strategies using vegetation indices and partial least squares regression.
- The result: PLSR reliably estimated chlorophyll (R2 =0.5, RMSE =2.05 mg/g freeze dry weight), maximum non-photochemical quenching (R2 =0.5, RMSE =0.57), and NPQ efficiency of PSII (R2 =0.53, RMSE =0.04), with green/red edge regions linked to pigments and photosynthesis but biomass and growth predictions remaining weak.
