Description
Blue Green Pigment Index (BGI) is a simple ratio index that compares reflectance in the blue (450nm) and green (550nm) regions of the spectrum. It is used to assess plant pigment content, particularly useful for detecting changes in chlorophyll and carotenoid concentrations that affect blue and green light absorption.
