Figure 2. Induction of sunflower broomrape germination by distilled water extracts of soybean rhizosphere soil in pot experiment.

Figure 2

The rhizosphere soil was collected from pot-grown plants at the (A) V1, (B) V3, (C) V5, (D) R2, and (E) R4 stages. Error bars represent the standard error of the mean. Different small letters above the error bars indicate significant differences at the 0.05 level (ANOVA and Duncan’s multiple range test). If any letter marked in one treatment is the same as the other one (in same color column), it indicates no significant differences between them.
