Abstract
Several naturally-occurring aromatic aldehydes and an aromatic alcohol inhibited potato tuber sprouting when applied as volatiles or directly as emulsions. Exposure to volatiles was for 1 or 10 days prior to placement into fresh air. Salicylaldehyde inhibited sprouting of tubers exposed for 1 or more days; benzaldehyde, cinnamaldehyde, cuminaldehyde and thymol suppressed sprouting of tubers exposed for 10 days. Direct application of cinnamaldehyde and benzaldehyde as 1% and 10% emulsions completely inhibited sprouting 14 days after treatment without apparent tuber damage. These compounds applied without dilution inhibited sprouting but damaged tubers.
