Other claims from this paper (19)
- Intervention effect Continuous light increased fresh and dry shoot biomass relative to normal light.
- Intervention effect A high red proportion gave high shoot fresh biomass.
- Intervention effect Shoot dry biomass remained unchanged with light quality.
- Intervention effect Continuous light promoted shoot carbon content and accumulation.
- Intervention effect Increased continuous light intensity promoted shoot carbon content and accumulation.
- Intervention effect Continuous light reduced shoot nitrogen, phosphorus and potassium contents.
- Intervention effect Continuous light reduced shoot calcium, magnesium, copper and zinc contents.
- Intervention effect Iron and manganese contents did not change under continuous light.
- Intervention effect Continuous light increased calcium, iron and manganese accumulation.
- Intervention effect Moderate continuous light intensity favored shoot nitrogen, phosphorus and calcium contents over 300 μmol·m−2·s−1.
- Intervention effect Moderate continuous light intensity favored magnesium, iron and manganese contents.
- Intervention effect Moderate continuous light intensity favored copper and zinc contents, while potassium was unaffected.
- Intervention effect Potassium content was not influenced by moderate versus high continuous light intensity.
- Intervention effect A 75% blue light ratio favored carbon content relative to lower blue ratios.
- Intervention effect The 3R1B light treatment gave higher carbon accumulation.
- Intervention effect The 1R1B treatment gave higher shoot N, P, K, Ca, Mg, Fe, Mn and Zn contents.
- Intervention effect Light quality did not affect copper content.
