  1. Control: tap water, Ly1: 215 mg/L lycopene, Ly2: 430 mg/L lycopene, D: 500 mg/L dithane, DLy1: 500 mg/L dithane + 215 mg/L lycopene, DLy2: 500 mg/L dithane + 430 mg/L lycopene. Lowercase letters in the same column indicate statistical significance between the means (p < 0.05). For rooting percentage and weight gain, 50 bulbs were used; for root elongation, ten bulbs were used in each group.
