Research on SPAD Estimation Model for Spring Wheat Booting Stage Based on Hyperspectral Analysis.

As can be seen from Table 2 , 29 of the 33 bands screened by wheat spectral reflectance reached highly significant levels ( p < 0.01) with the measured SPAD, but the correlation coefficients were distributed in the range of 0.419–0.475, which was generally low.
