Abstract: Some red edge parameters(red, Min600-720λ, dredλ, dminλλ, dred / dmin∑λ, d680-750λ, andnir) and the relationship between these parameters and the parameters of biochemistry and biophysics of winter wheat were studied by regression analysis. The results indicated that there existed some changes in these red edge parameters in the whole growth stages, and there were strong correlations between red edge parameters and parameters of biochemistry and biophysics. Thus, the red λedge parameters were found valuable for assessment of wheat parameters of biochemistry and biophysics. Thered can be used to λestimate the soluble sugar content and the chlorophyll content. The dred was the best estimator of total nitrogen content. LAI can λbe estimated by Min600-720 satisfactorily.
