Plant growth-promoting bacteria have several abilities to promote plant growth and development. One of these skills is the synthesis indole-3-acetic acid (IAA), which mainly promotes root shoot The Bacillus subtilis Azospirillum brasilense been widely used in agriculture with this function. However, little known about whether joint inoculation can reduce development by excess IAA produced as a result inoculation. objective present study was verify effect on B. A. three tomato genotypes. Micro-Tom genotype without mutation for synthesis, Entire, has high sensitivity IAA, diageotropic (dgt) low IAA. results show that parameter most sensitive microbial number roots. No treatment increased dry mass parameters dgt, genotype, height Entire genotypes, area volume dgt.
