Plant growth promoting rhizobacteria can inhibit the in vitro germination of Glycine max L. seeds

Utilization of plant growth promoting rhizobacteria (PGPR) in order to increase the productivity may be a viable alternative to organic fertilizers. The main goal is to reduce the pollution and to preserve the environment in the spirit of an ecological agriculture. Because soybean represent a crop of major economic importance, a study was performed to analyze the impact of some rhizobacteria isolated from soybean roots on the on the germination process of Glycine max L. seeds, taking into account the aspartate- and alanin-aminotransferase activities. The results showed that in the early stages, rhizobacteria has an inhibitory effect on the germination process.
