Abstract:
To explore the effect and mechanism of salicylic acid (SA) treatment on physiologica indexes of Tomato, Tomato were immersed in concentrations (0.1 g/L) of solution, respectively for 5 minutes and stored under the conditions of (2±1) ℃ and 25 ℃, contents of protein and the activities of resistance related enzymes in postharvest tomato were measured with Colorimetry. Results showed that SA treatment resulted the contents of protein and the activities of resistance related enzymes significantly enhanced after SA treatment. And the result of eparation gel concentrations showed that small molecule induced protein was appeared. In conclusion, SA treatment can lead the pathogenesis-related protein to express.
