摘要： Pesticides are one of the abiotic stresses that have had an impact on the quality of agricultural products, especially in China. This study was the first to explore the soluble protein (SP) accumulation, peroxidase (POD) activity, and superoxide dismutase (SOD) activity variations in the stem and leaf of celery plants in the field after 2 h, 1, 3, 5, 8, 10, 14, 21, 28-day of spraying imidacloprid (IMI) and fenpyroximate (FEN) at various doses. The findings demonstrated that there was no notable difference in ultimate residues between 1 F and 10 F, and even with the 10 F treatment, the residues were not a concern. The SP accumulation alterations were mainly provoked by residues, which dramatically boosted in stem and eventually declined in leaf. The POD activity in celery was a dynamic process with a marked shift (enhanced and declined) when compared with non-pesticide treatment after 28 days. The field trial exhibited that the SOD was principally positioned in leaf whether pesticides were applied or not, which might be due to the distinctive structure of the celery leaf compared with the stem. No obvious linear relation between application dose and SOD activity was observed.
