Rhythmic emission of methyl benzoate and ethyl benzoate in L. ‘Siberia’ flowers. (A) Changes in floral volatile methyl benzoate (A) and ethyl benzoate (B) during two consecutive light/dark (12-h/12-h) cycles on the day after full-opening. White and grey areas correspond to light and dark, respectively. Error bars indicate standard deviation of three biological replicates. Different lowercase letters labeled on bars indicate the statistically significant differences at the level of P < 0.05.
