Root, shoot length, and germination index of wheat seeds in the presence of PSL extract.

Concentration (%)	Root length (cm)	Shoot length (cm)	Germination index (%)	Inhibition percentage
Control	5 ± 0.22^a	9.4 ± 0.6^a	100	0
0.001	4.5 ± 0.17^ab	7.4 ± 0.45^b	90	10
0.01	4.1 ± 0.09^bc	6.5 ± 0.19^bc	82	18
0.1	4.0 ± 0.31^bcd	6.2 ± 0.11^bc	80	20
1	3.5 ± 0.13^cd	5.3 ± 0.51^cd	70	30
10	2 ± 0.11^e	4.6 ± 0.28^d	40	60

Values are Mean ± S.D of three different experiments. Data were subjected to one-way ANOVA analysis and differences among treatments were determined by Tukey’s test. Different letters mean statistical differences at < 0.05.
