Plant and Soil Aims and scope Submit manuscript

Summary

Seeds of cucumber were inoculated with two different fluorescent Pseudomonas cultures and grown in peat. The establishment of the introduced pseudomonads as well as of spontaneously developing Pseudomonas populations in the rhizoplane was studied. It was found that the pseudomonads were able to compete successfully in the rhizoplane of young cucumber plants. However, they did not keep their position in the predominating populations for more than a restricted, comparatively short period. After eight weeks, at the flowering stage of the cucumber plants, they were hardly detectable among other bacteria in the rhizoplane.
