P. aegyptiaca seed germination rate under different conditions.

Treatment	Germination (%)
	No Conditioned	Conditioned	Conditioned and GR24 Treatment
BR	0 a	0 a	83.3 ± 3.8 fg
GA3	0 a	2.2 ± 2.2 a	94.4 ± 1.1 h
ABA	0 a	0 a	0 a
Ethephon	0 a	0 a	90.0 ± 1.9 gh
Fluridone	26.5 ± 1.8 b	7.8 ± 2.9 a	86.7 ± 5.7 gh
GA3 + Fluridone	35.6 ± 1.1 c	10.0 ± 3.3 a	91.1 ± 2.2 gh
Ethephon + Fluridone	24.4 ± 2.2 b	7.8 ± 1.1 a	80.0 ± 5.0 f
GA3 + Ethephon + Fluridone	47.8 ± 2.9 e	20.0 ± 1.9 b	91.1 ± 4.0 gh
Water	0 a	0 a	75.6 ± 9.1 f

“No conditioned” means that the dormant seeds were treated for 9 days directly without conditioning. “Conditioned” represents seeds conditioned in water at 25 °C in the dark for 7 days and then treated with plant hormones or inhibitor for 2 days. “Conditioned and GR24 treatment” involved seeds conditioned in water at 25 °C in the dark for 7 days and then treated with GR24 and other plant hormones or inhibitor for 2 days. The concentrations of hormones or inhibitor were as follows: BR, 1 mg/L; GA3, 10 mg/L; ABA, 1 mg/L; fluridone, 100 mg/L; ethephon, 500 mg/L at pH 5; and GR24, 10⁻⁶ mol/L, all the hormones were dissolved in 0.1% ethanol (v/v), except GR24 and fluridone were dissolved in 0.1% acetone (v/v). Means within a column followed by the same letter do not differ significantly according to Fisher’s protected LSD test (p < 0.05).
