研究了丛枝菌根真菌(AMF)、促进植物生长的根际细菌(PGPR)荧光假单胞菌RA56与小麦全蚀病病原菌Gaeumannmyces graminis之间的相互作用。在2年的温室条件下，研究了其对植物生长、产量、种子质量和抗逆性的影响。接种绿僵菌或荧光假单胞菌RA56的植株比未接种的植株生根病发病率低。4周后，荧光假单胞菌RA56菌株与AMF联合接种效果最好。此外，丛枝菌根真菌对侵染小麦的处理还能提高小麦的地上部干重和种子产量。在菌根方面效果最好。用10%菌根接种剂记录定植情况。
The interaction between the arbuscular mycorrhizal fungus (AMF) Glomus mossea, the plant growth promoting rhizobacteria (PGPR) Pseudomonas fluorescens strain RA56 and the take-all pathogen Gaeumannomyces graminis, were investigated on spring wheat (Triticum aestivum L.). The subsequent effects on growth, yield, seed quality and resistance of plants were investigated under greenhouse conditions over a 2-year period. Plants inoculated with G. mosseae or P. fluorescens strain RA56 had a lower incidence of the root take all disease than untreated ones. The combined inoculation of P. fluorescens strain RA56 and AMF showed the best results in reducing pathogen impact at 4 weeks. Furthermore, prior treatment with AMF resulted in an increase in shoot drymass and seed yield in G. graminis infected wheat. The best results in terms of mycorrhiza. colonization was recorded with 10% of mycorrhiza inoculum.
