Other claims from this paper (11)
- Observation In the short-term continuous cropping soybean field the Fusarium spp. population density was 6.0 x 10^4 CFU per g.
- Observation In the short-term continuous cropping field, F. oxysporum, F. graminearum and F. verticillioides (high pathogenicity) and F. solani (moderate pathogenicity) were the dominant species.
- Intervention effect Under long-term continuous cropping the population density of F. oxysporum was only 36% of that under short-term cropping.
- Intervention effect Under long-term continuous cropping the population density of F. graminearum was only 32% of that under short-term cropping.
- Intervention effect Under long-term continuous cropping the population density of F. solani was only 22% of that under short-term cropping.
- Observation F. verticillioide, the most pathogenic species, was absent in the long-term continuous cropping field.
- Observation The diversity and evenness indices of the Fusarium population were significantly higher under long-term than short-term continuous cropping.
- Observation F. tricinctum, F. lateritium and F. avenaceum were isolated only from the long-term continuous cropping field.
- Observation The species found only under long-term cropping were distantly related genetically to highly pathogenic Fusarium isolates, based on ITS and EF-1 alpha sequences.
- Observation These Fusarium species were non-pathogenic to soybean.
- Intervention effect The authors conclude that long-term continuous soybean cropping seemed to inhibit soil Fusarium population size, alter community composition and genetic diversity, and even decrease pathogenicity of the Fusarium population for soybean root rot.
