Figure 3From: Eliminating interference by anthocyanin in chlorophyll estimation of sweet potato (Ipomoea batatas L.) leavesCoefficients between [(R λ )-1- (R NIR )-1] and [(R NIR / R λ ) - 1] and the chlorophyll content and their RMSE. (A) Coefficient between [(Rλ)-1 - (RNIR)-1] and the chlorophyll content; (B) coefficient between [(RNIR/Rλ) - 1] and the chlorophyll content; (C) root mean square error (RMSE) of chlorophyll estimation by R-1.Back to article page
