Einfluss von Pseudomonas fluorescens auf Ertrag von Weizen und mikrobielle Biomasse des Bodens

Summary

P. fluorescens is used in agriculture and horticulture as a plant growth promoting
rhizobacterium. It colonizes root surfaces effectively and excretes compounds that are
influencing plant nutrient uptake and plant health. Soils with different initial biological
fertility were analysed 18 and 60 days after inoculating the freshly sown wheat plants
with a suspension of a rifampicine tolerant strain of P. fluorescens CHA0, in order to
evaluate its survival and lasting effect on soil microbial biomass. P. fluorescens had a
lasting effect in soils with low initial biomass, but no lasting effects were found in
biologically active soils.
