Fig. 3From: Physiological and protein profiling analysis provides insight into the underlying molecular mechanism of potato tuber development regulated by jasmonic acid in vitroEffect of exogenous JA on the H2O2 content and antioxidant enzyme activity of tubers in vitro. After 40 days culture, the H2O2 content (A), SOD activity (B), APX activity (C) and CAT activity (D) of tubers were measured. Data are presented as means ± SE for three independent experiments. Different letters indicate that the means differ significantly (p < 0.05) according to Duncan’s multiple range testBack to article page
