Pre-sowing seed treatment and foliar spray treatments with 10, 25 and 50 mg/L ascorbic acid (AA) were given to the pale variety of Indian dill (Anethum sowa Roxb.). Although AA treatment did not bring any significant change in crop yield, there was a significant increase in the oil yield from the fruit. It was also found that concentrations of limonene, carvone, and cis- and trans-dihydrocarvone were higher in oils from AA treated plants. At the same time, dillapiole, an undesirable component, was found in lower concentrations in these oils. The best quality oil with the highest total carvone/dihydrocarvone content and lowest dillapiole content was realized from plants treated with 50 mg/L AA.
