In this study, differences were noted in the effectiveness of using
the same inoculation methods for grass and rape. Application of
Method 1 and 3 of bacteria inoculation seems to be the most favorable
for the PGPR bacteria effectiveness. Method 1 of inoculation,
applied during the germination of seeds for 48 h on plates with
a bacterial suspension, seems to be the most suitable for fescue
grass. Inoculation of plants during germination with PGRP bacteria
is an efficient method for protecting seeds from growth inhibition
caused by toxic and poor soil properties. Moreover for rape plants,
the inoculation with bacteria directly to soil after two weeks of
growth stimulates the roots growth most effectively. The bacteria
associated with plant rhizosphere naturally occurring in contaminated
areas stimulate plant growth due to the biochemical activity
and thus improve the soil phytoremediation process. In future are
expected that PGPR replace the artificial growth regulators, chemical
fertilizers, pesticides which have numerous side-effects.
