Decoupling the chemical and physical origins of the seed spectral manifold in sorghum.

Abstract excerpt

Biological structures interact with light as complex manifolds, yet genomic studies often reduce these phenotypes to scalar traits. Here we resolve the sorghum seed spectral manifold into separable axes corresponding primarily to pigment-associated and structure-associated optical variation. Path analysis indicates that near-infrared (NIR) reflectance is associated primarily with an indirect path through seed...
