Floral volatile profiles of Petunia x hybrida ‘Mitchell Diploid’ (MD) and ir-PhCSE plants were identified by gas chromatography analysis. The fully opened flowers from three months old plants were harvested and the volatiles were collected for 1 h. The calculated emissions were compared to MD plants. Data represent mean ± SD, and the bars on the graphs indicate standard deviation. Asterisks (*) indicate that the volatile amounts of ir-PhCSE plants are significantly different compared to MD (p < 0.05, Student’s t-test; ns, not significant)
