Mean values of main plant characteristics and quality measurements.

	Plant height (cm)	Shoot diameter (mm)	Number of leaves per plant	Fresh weight (g)	Number of flowers in the second week	Lycopene content (𝜇g/100 g fresh weight)
Control	144.4^a	15.5^b	34.5^d	842.9^d	14.6^c	6083^a
MF-5	104.8^d	16.1^b	31.6^c	834.3^c	15.2^b	6130^a
MF-10	132.4^c	16.3^ab	47.3^b	964.0^b	15.0^bc	6122^a
MF-15	138.1^b	17.0^a	50.8^a	968.7^a	16.3^a	6214^a

Control: untreated seeds; MF-5, M F-10, and MF-15: seeds treated with pulsed electromagnetic field for 5 min, 10 min, and 15 min, respectively.
^a,b,c,dMeans followed by the same letter for treatments are not significantly different according to the least significant difference (LSD) test.
