In vitro analyses are not reliable predictors of the plant growth promotion capability of bacteria; a Pseudomonas fluorescens strain that promotes the growth and yield of wheat

Abstract

While this study has identified a candidate for further field tests, it has also highlighted the fact that the modes of action for plant growth-promoting bacteria (PGPB) are still not fully understood, and that there is no efficient and effective screening method for identifying PGPB by laboratory tests.
