ABSTRACT

Endophytic Bacillus spp. can promote plant growth but the specific
mechanisms involved in such interrelationships have not all been well characterized.
A sub-sample of 7 strains putative endophytic Bacillus spp. isolated from
different maize cultivars were tested as seed inoculants of host-cultivar of
maize and winter wheat under laboratory conditions. The tested strains showed
different level of plant growth promoting attributes like
indole-3-acetic
acid production and antagonistic activity against several phytopathogens in
vitro
. None of the Bacillus strains stimulated seedling
development of the host maize cultivar and winter wheat on sterile water agar.
Three
strains, B. methylotrophicus A17, B. simplex A8 and B. megaterium A66
were found to harmfully affect seed germination under abiotic conditions. Above-mentioned
3 strains and also B. aerophilus A62 and B. megaterium A54 inhibited
primary root development of the maize host cultivar. On the contrary, only B.
megaterium
A53 neutral to native cultivar had a deleterious effect on seed
germination of non-host winter wheat plants.


Studies in vitro of endophytic Bacillus strains did not demonstrate
correlations among the ability of auxin production, inhibition of pathogens,
nitrogen fixation, and stimulation of seed germination and seedling development
of host as well as non-host plants.

Key words: Bacillus spp., putative endophytes, Zea mays, auxin.
