  1. Control: Tap water, RP 1: 0.5 g L−1 R. pollinaria extract, RP 2: 1.0 g L−1 R. pollinaria extract, Al: 50 mg L−1 AlCl3, AlRP 1: 50 mg L−1 AlCl3 + 0.5 g L−1 R. pollinaria extract, AlRP 2: 50 mg L−1 AlCl3 + 1.0 g L−1 R. pollinaria extract. ECD: epidermis cell damage, FN: flattened nucleus, INN: increase in the number of nucleoli, CCD: cortex cell damage. (-): no damage, (+): low damage, (++): moderate damage, (+++): severe damage. A total of 10 bulbs were used per group (n = 10). From each bulb, 10 root cross-sections were obtained, resulting in 100 sections per group. 0–5 damage: (–) No damage; 6–25 damage: (+) Low damage; 26–50 damage: (++) Moderate damage; 51 or more damage: (+++) Severe damage.
