Effect of the strain Trichoderma longibrachiatum T6 on wheat seed germination at the different NaCl solutions.

Treatment	Salt Concentrations (mg mL−1)	Germination Rate (%)	Germination Potential (%)	Germination Index (%)
Trichoderma longibrachiatum T6	0	96.0 ± 1.2a	89.0 ± 1.2a	74.2 ± 0.7a
	10	83.3 ± 1.4b	65.0 ± 1.2c	52.2 ± 1.2c
	20	68.3 ± 1.7d	51.3 ± 1.4e	40.2 ± 0.7e
Sterile water	0	93.3 ± 1.2a	82.0 ± 1.2b	68.1 ± 1.2b
	10	78.0 ± 2.3c	61.3 ± 0.8d	44.9 ± 1.2d
	20	63.3 ± 1.2e	47.0 ± 1.2f	38.0 ± 1.7e

Data are means ± standard error of replicates, and the germination rate, potential and index were determined 5, 3 and 5 days after treatment, respectively. Different letters in the same column denote significant differences at the p < 0.05 level by Duncan’s new multiple range test (n = 12). In the three TL-6 treatments, wheat seeds were presoaked with the suspension of Trichoderma longibrachiatum (TL-6) spores for 12 h, whereas in the three sterile water treatments, wheat seeds were presoaked with sterile water only.
