Figure 2. Stability of zinniol over time.
Synthetic zinniol was added to Gamborg medium in order to check its stability over time under our experimental conditions (dark, 22°C, shaking). HPLC was used to measure variations in the zinniol concentration over a time course. Three different HPLC analyses were performed for each time. Zinniol concentrations were divided by the initial zinniol concentration in the medium, giving a relative zinniol concentration (noted % to). Except for small (less than 2%) random variations, the zinniol concentration did not vary over time, indicating stability. Standard errors are not represented because they were smaller than the dots we used.
