Changes in MDA content under drought stress before and after DBD plasma treatment. (The discharge voltage is 13.0 kV, and the DBD plasma treatment time is 4 min. Samples are collected on the 4th day of planting. Data are presented as the mean ± SD (n = 3). Different lower case letters (a–d) indicate statistically significant differences at the P < 0.05 level).
