| Outline of Final Research Achievements |
As physiological disorder of tomato fruits, heart rot tomato fruits were harvested at the first flower truss under high air temperature condition in high technology greenhouse. Since heart rot of tomato fruit is apparently same as normal fruit, non-destructive detection method for heart rot tomato fruit using spectrum analysis were developed in this study. The spectrum at the blossom end of fruit was detected with spectrophotometer. The detection wavelength was from 500 nm to 1010 nm with 2 nm sampling interval.
Our results showed that heart rot tomato fruit had a peak around 600 nm in second derivative spectra and these were different with normal fruit (around 600 to 650 nm). These wavelengths may be used for detection of heart rot tomato fruits. Furthermore, tomato fruits with heart rot was detected with the image obtained by the infrared camera non-destructively.
