Abstract: | Summary At least 105–106 viable cells of the rhizopseudomonad strain 7NSK2* had to be applied per seed of maize cultivar Beaupré and barley cultivar Iban in order to obtain a beneficial effect on plant growth under greenhouse conditions. In pot experiments where an increase in plant growth, varying between 15% and 25%, was observed, the introduced strain 7NSK2* constituted at least 20% of the bacterial root colonizers. This colonization provoked a shift in the fungal rhizospheric community. Due to the inoculation with 7NSK2, Penicillium spp. became the dominant isolates, while Trichoderma spp. were the dominant isolates in pot experiments with low and inefficient inoculum levels of 7NSK2*. |
