Enhancement of ethylene production by salicylic acid during aging of potato tuber slices

Abstract

Salicylic acid (SA) treatments significantly increased the ethylene production of potato (Solanum tuberosum L.) tuber slices during aging process of 24h. The concentration and pH value of SA solution, aging temperature and the physiological state of potato tubers had some influences on the extent of this enhancement by SA, in that the effect was positively correlated to the concentration of SA up to 90#mu#mol·L~(-1), and was much higher in slices aged at 30 degree C than in those aged at 20 degree C. In addition, the effect of SA in slices from dormant potato tubers was stronger than in those from sprouting ones, and was observed at its maximum under pH 6.4.
