Waterlogging stress had different effects on the physiological indicators of WT and the am mutant. a–f The chlorophyll a (a), chlorophyll b (b), total chlorophyll (c), anthocyanin (d), MDA (e) and soluble sugar (f) contents were determined in the WT and am mutant after 12 d of waterlogging stress. Error bars represent the SDs from three replicated experiments. Significant differences between the am mutant and WT with and without (CK) waterlogging stress are indicated (Student’s t-test) as follows: ***P < 0.001; **P < 0.01; *P < 0.05
