Title
A novel combined spectral index for estimating the ratio of carotenoid to chlorophyll content to monitor crop physiological and phenological status.
Abstract
•A novel combined carotenoid/chlorophyll ratio index (CCRI) in the form of CARI divided by CIred-edge for the assessment of the ratio of Car to Chl content was proposed.•CCRI showed consistently accurate and robust estimation of the ratio of Car to Chl content with varied measured datasets acquired at both the leaf and the canopy scale.•Correlation between leaf chlorophyll and carotenoid content could affect the estimation accuracy of CCRI on the assessment of the ratio of Car to Chl content.
