| Abstract: | Cotton plants were fumigated under SO2 in a dynamic fumigation cabinet, at a concentration of SO2 2ppm, and a duration of 8 hours. Spectral reflectance from leaves and the differential spectrum were measured. It was found that spectral reflectance changed for the cotton leaves damaged by SO2. In the region of visible spectrum, reflectance increased, while in the region of near infra-red, reflectance decreased. And spectral reflectance curve shifted towards the blue. All these suggested an idea that some spectral bands may be applied to distinction between normal and SO2-damaged cotton leaves by way of spectral reflectance characteristics. |
