摘要：
The influence of salicylic acid (SA) on ethylene formation in aged potato (Solanum tuberosum) tuber slices was investigated. SA treatments significantly stimulated ethylene production of the slices during 24 hr of ageing. Up to 90 mu M SA (the highest concentration tested), the stimulation was positively correlated with concentrations. SA showed stimulation effects on ethylene production at pH 5.4, 6.4 and 7.4, with the greatest stimulation at pH 6.4. These results show that SA enhances endogenous ethylene formation in aged potato tuber slices. This stimulation effect of SA is different from the general conception that SA ultimately inhibits ethylene biosynthesis in plants. Copyright (C) 1996 Elsevier Science Ltd
