Abstract: In order to measure the SOD activation of rice leaves by absorption spectra under sulfur dioxide fumigation condition, the correlation between the SOD activation and spectral absorption of rice leaf was studied in an area experiment under sulfur dioxide fumigation condition. Results showed that the correlation curve had two peak points in all the growth stages, located between 520-550 nm and 720-750 nm bands. The average A1 and A2 were calculated by 720-750 nm and 520-550 nm bands. The spectral variables were formed by A1 and A2, and the spectral variables infer SOD activation. The study found that, in the whole rice growing period, the Logarithmic sum of variable correlation spectroscopy and superoxide dismutase activity correlated significantly improved. The model of SOD activation was built by selecting logarithm adding. This article proposes some exploring research for measuring the SOD of rice under sulfur dioxide fumigation condition.
