Figure 7From: Eliminating interference by anthocyanin in chlorophyll estimation of sweet potato (Ipomoea batatas L.) leavesValidation results for the index, 1 - (R λ /R NIR ), calculated using broad-band spectra R 550~590 (A) and R 700~740 (B) from independent datasets. The coefficients between the predicted and actual measured chlorophyll contents were r2 = 0.94 (A) and 0.94 (B).Back to article page
