Plasma discharge time: 30 min, treatment time: 30 min.
Means followed by the same lowercase letter within a column are not significantly different between the same treatment, while those followed by the same uppercase letter within a row are not significantly different between the treatments in the same property stored at each storage day (p>0.05).
