Table 1

The germination percentage of seeds, shoot length, root length, and number of seminal roots in H. vulgare L. seedlings grown 7 days with 0, 1, 2, and 4 mg/L of ZnO NPs.

	Germination (%)	Shoot length (mm)	Root length (mm)	Seminal roots (n)
Control	42 ± 1.57	36.8 ± 2.09	28.2 ± 0.91	6.8 ± 1.1
1 mg/L	63 ± 1.82	49.3 ± 2.39	36.4 ± 0.89	7.2 ± 0.84
2 mg/L	57 ± 1.76	46.5 ± 1.67	33.6 ± 0.67	7.6 ± 0.55
4 mg/L	66 ± 1.89	52.4 ± 1.53	43.4 ± 1.48	7.8 ± 0.84

Values are the mean of three replicates with SD. Significant difference from control (); significant difference from control ().
