Validation results for the index, [1 - (R λ /R NIR )], calculated using R 550 (A) and broad-band spectra R 550-590 (B) from rice data. The coefficients between the predicted and actual measured chlorophyll contents were r2 = 0.91 (A) and 0.92 (B). The solid line represents the equation Chl pred = Chl meas , and the dotted lines represent the root mean square error of the chlorophyll prediction.
