Canopy Spectral Reflectance Feature and Leaf Water Potential of Sugarcane Inversion

摘要：

The canopy hyperspectral reflectance data and leaf water potential were recorded at tillering and elongation stage of sugarcane. Statistic analysis method was conducted on the correlation between canopy reflectance data and leaf water potential, combining the visible light band (460nm or 560nm) and the infrared light band (860nm or 960nm or 1200nm) reflectance into vegetation indices of RVI (ratio vegetation index) and NDVI (normalized difference vegetation index), the ratio of RVI and NDVI was linearly related to leaf water potential. Five single variables of linear function models against the leaf water potential were established, the results showed that the five types of function models had significant correlation if a =0.01, the two model established by using of the band 460nm and 1200nm, 560nm and 960nm were optimal and the correlation coefficient was 0.927.
