The changing of antioxidant enzyme activities and endogenous hormones in WT and OE plants. Six-weekend tomatoes were used as materials to detect enzyme activities and endogenous hormones. (a). POD, SOD, and CAT enzymes activities were determined in WT and OE plants under 4 ℃ for 0 h, 6 h, 12 h, 24 h, 48 h. b. (b). The content of IAA and ABA was determined, and ABA/IAA was calculated in WT and OE plants under 4 ℃ for 0 h, 6 h, 12 h, 24 h, 48 h. The bar represents the value of standard error (p < 0.01). Lowercase letters represent the significance level. Means and SE values were calculated from at least three independent experiments
