Abstract
Reflectance spectra of living wheat’s leaves were acquired by portable radiation spectrometer. Multivariate scatter correction (MSC) method was used to preprocess the spectra, and quantitative analysis detection models were built up by artificial neural networks (ANN). The models of chlorophyll, chlorophyll a, and chlorophyll b in leaves were built up and tested. In calibration set and predicted set, for chlorophyll in leaves, the correlation coefficient (R) were 0.927 and 0.818, the standard deviation (SD) were 0.252 and 0.470; for chlorophyll a in leaves, the correlation coefficient (R) were 0.780 and 0.627, the standard deviation (SD) were 0.441 and 0.592; for chlorophyll b in leaves, the correlation coefficient (R) were 0.876 and 0.871, the standard deviation (SD) were 0.205 and 0.259. The results show that, using portable radiation spectrometer to acquire the reflectance spectra, multivariate scatter correction to preprocess the spectra, and artificial neural networks to build up the models, the chlorophyll, chlorophyll a and chlorophyll b in winter wheat’s leaves may be quantitative detected.
