Notes:
Plant growth promotion characteristics of five bacterial strains IAC/BECa 99 (Kosakonia radicincitans), IAC/BECa 128 (Enterobacter asburiae), IAC/BECa 135 (Burkholderia tropica), IAC/BECa 141 (Pseudomonas fluorescens), and IAC/BECa 152 (Herbaspirillum frisingense).
Positive (+) and negative (−) signals mean positive and negative result for each plant growth promotion traits listed.
