Other claims from this paper (6)
- Intervention effect Light transmittance through the rapeseed canopy decreased linearly as crop seeding rate increased from 1.8 to 9.0 kg ha -1.
- Intervention effect Increasing rapeseed seeding rate did not influence rapeseed aboveground biomass, seed yield or harvest index.
- Intervention effect Increasing rapeseed seeding rate negatively affected rapeseed seed oil content in one of two site-years.
- Intervention effect In the greenhouse, declining irradiance reduced flixweed biomass, root allocation and photosynthetic light compensation point.
- Intervention effect Flixweed leaf allocation, foliage area ratio and specific foliage area increased in response to decreasing irradiance.
- Recommendation The authors caution that higher rapeseed seeding rate might not be an adequate control strategy alone because flixweed shows shade-tolerant characteristics.
