Abstract For estimating the yield of wheat, and for crop growth monitoring by using hyperspectral remote sensing, it is very important to quantitatively determine the chlorophyll and water contents in live leaf of winter wheat. In the range of 350-1 650 nm, the reflectance spectrum of winter wheat’s leaf in different growth periods were scanned by ASD FieldSpec® Pro FR portable spectrometer and LI-COR 1800 integrating spheres. Partial least squares method was used to develop the quantitative analysis models for chlorophyll and water contents with reflectance spectroscopy. The model of chlorophyll content with reflectance spectroscopy was built in the range of 400-750 nm, and the results show that the correlation coefficient between the estimated values and the real values is 0.898, and relative standard deviation is 13.6%. The model of water content with reflectance spectroscopy was built in the range of 1 400-1 600 nm, and the results indicate that the correlation coefficient between the estimated values and the real values is 0.999, and relative standard deviation is 0.3%. These results are satisfying in agricultural production.
