We studied the effect of lectins of Azospirillum brasilense Sp 7 on germination capacity of tomato, cucumber, pea, wheat, and onion seeds. The lectins proved to inhibit seed germination. We studied the effect of different concentrations of lectins from four azospirilla strains on the rate of wheat seed germination. Both inhibiting and stimulating effects were demonstrated. Lectin-induced changes in the mitotic state of plant cells were demonstrated with histological sections of the root growing point in onion.
