Abstract: Lettuce is bolting easily under high temperature stress. To explore the role of endogenous ethylene in the process of lettuce bolting, we used the gas chromatography to measure the ethylene release content, compared the effects of different time, sampling parts, temperatures, light and moisture conditions on ethylene release. The results showed that the optimal sampling part was stem, the time was 6 h and the temperature was 30℃. We also optimized the chromatographic condition at the same time, made ethylene and air separate better, and got the symmetrical peak of stable baseline.
