Organogenesis of cabbage in in vitro cultures: A – shoot induction from cut ends of treated hypocotyl on shoot induction medium in control (bar = 0.5 cm); B – shoot induction from trifluralin treated callus on shoot induction medium (bar = 0.5 cm); C – green dormant callus from treated calli on shoot induction medium (bar = 0.5 cm); D – germinating seeds treated with trifluralin after seven days on seed germination medium (bar = 1 cm); E – growing calli from treated hypocotyls after 14 days on shoot induction medium (bar = 0.5 cm); F – rooted shootlets derived from treated seeds

Effect of cultivar, trifluralin concentration, treatment condition on in vitro culture of seeds and their interaction with each other: A1, B1, C1 – the effect of different treatment conditions on the rate of seed germination, shoot induction, and root induction respectively; A2, B2, C2 – the effect of different cultivars on the rate of seed germination, shoot induction, and root induction respectively; A3, B3, C3 – the effect of different concentrations of trifluralin on seed germination, shoot induction, and root induction respectively. Vertical bars denote 0.95 confidence intervals
