The screening results showed that application of endophytic
bacterial strain MPB 2.1 culture significantly enhanced the
development of tomato seedling. The Shoot length, Shoot weight, Root
length, and chlorophyll contents were significantly boosted by the
application of MPB 2.1 culture (Fig. 5a). The length of shoot and root
were paralleled with control and it is deciphered from the results that
the tomato plantlet treated with endophytic bacterial strain MPB 2.1
showed upsurge in length 2.5 cm and 3.5 cm respectively. Almoneafy
et al. [28] noted a positive correlation (0.777 and 0.686) between the
IAA amounts produced by Bacillus strains of bacterized tomato plants
inside the greenhouse which showed that these bacterial strains are
promoting the growth of tomato plants. Additionally, this was the first
report which demonstrated the mode of antibacterial effect of Bacillus
strains against R. solanacearum.
