Effect of Rhizobacteria and Metham-Sodium on Growth and Root Microflora of Celery Cultivars

(...) Early-season plant growth promotion did not necessarily correlate with shoot weight of plants at harvest. Some qualitative and quantitative differences in fungal microflora on roots were observed in the different bacterial and chemical treatments, but, in general, the detection methods for evaluating the seasonal succession of microflora under field conditions were too insensitive and labor-intensive to conclusively relate plant growth promotion to the presence or absence of specific microorganisms, including F. o. apii
