Analysis of interspecific relationships betweenFunneliformis mosseaeandFusarium oxysporumin the continuous cropping of soybean rhizosphere soil during the branching period

摘要: This study analysed the interspecific relationships between dominant arbuscular mycorrhizal (AM) fungus, Funneliformis mosseae, and major soybean root rot pathogen, Fusarium oxysporum, in rhizosphere soil of continuous cropped soybean. Our aim was to provide theoretical evidence on AM fungi overcome obstacles cropping. We selected cultivars, including Kenfeng 16 (an intermediate cultivar), Heinong 44 (a high-fat cultivar) 48 high-protein sowed cropping under different treatments. The infection status roots during branching period by Fu. mosseae F. oxysporum estimated using standard polymerase chain reaction method, as well their colonisation soil. fungal rates disease incidence were determined, respectively. Quantitative applied analyse DNA content ...
