The average number of roots per seedling (a), the average root length per seedling (b), and the average length of the shortest root per seedling (c) in untreated (Control) seeds, seeds exposed to vacuum (Vacuum control), and CP-treated seeds in the glow regime for 30 (G30) or 90 s (G90), and in the afterglow regime for 30 (AG30) or 90 s (AG90). Displayed values are the mean ± SE of three replications. Different letters (a, b) indicate statistically significant differences among treatments according to Duncan’s test (p < 0.05).
