Transferable spectral models for high-throughput estimation of winter wheat net photosynthetic rate: a cross-scale approach using leaf and UAV hyperspectral data
Introduce Net photosynthetic rate (NPR) is a key indicator of photosynthetic capacity that directly governs the production and accumulation of biomass. Non-destructive sensing techniques based on multi-scale sensors (e.g. field spectroradiometers and UAV platforms) face challenges in simultaneously achieving high accur...
