Other claims from this paper (10)
- Intervention effect Dodder invasion combined with silicon nutrition synergistically increased the activity of superoxide dismutase and catalase in niger.
- Observation Niger without silicon nutrition and without dodder contained 235 mg silicon kg−1 dry weight.
- Intervention effect Dodder reduced the silicon content of niger by 38.3%.
- Intervention effect The combination of K2SiO3 and silicate-solubilizing bacteria synergistically increased niger silicon content by 195.7%.
- Intervention effect Dodder-parasitized niger grown in K2SiO3-treated, SSB-inoculated soil showed a threefold increase in lignin content.
- Intervention effect A similar increase was observed in the activity of phenylalanine ammonia-lyase, an enzyme of lignin biosynthesis, in dodder-parasitized niger in K2SiO3-treated, SSB-inoculated soil.
- Intervention effect The combination of K2SiO3 and SSB improved the seed yield of dodder-parasitized niger by 126.1%.
- Intervention effect K2SiO3 and SSB applied individually were ineffective in improving the seed yield of dodder-parasitized niger.
- Intervention effect None of the treatments affected grain oil content, which stayed between 36% and 38%.
- Recommendation The authors suggest that soil inoculated with SSB and treated with K2SiO3 can help mitigate dodder damage in niger.
