Table 1.
Wheat seed germination and seedling growth 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. GP is sampled on the 1st day of planting. GR4, root length, and shoot length are sampled on the 4th day of planting. GI and GIDR are sampled on the 8th 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).
