statistically significant difference. For root length
(
Kruskal-Wallis: H

=8.226; P=0.144) and number of
leaves (Kruskal-Wallis: H

=6.326; P=0.276), all the
treatments were similar to one another. Furthermore,
for mass of fresh matter (ANOVA: F=14.616; P<0.001)
and of dry matter (ANOVA: F=4.412; P=0.002), the
bacterial strains did not present a positive effect.
It can be inferred that after immersing the cabbage
seeds in bacterial cultures, the bacteria adhered to the
seeds. Then, by natural openings that were formed
during the germination and seedling development
process, bacteria penetrated and colonized the plant
