(A) α-ketoglutaric acid; (B) shikimic acid; (C) oxalic acid; (D) malic acid; (E) ascorbic acid; (F) tartaric acid; (G) citric acid; (H) succinic acid. CK: normal irrigation, spontaneously once in 3 days; MD: irrigating once in 6 days. The histogram includes a short vertical line that indicates the mean ± SE (n = 3), while asterisks highlight significant differences between treatments based on the Student’s t-test (* p < 0.05, ** p < 0.01, *** p < 0.001, ns: There was no significant difference).
