Other claims from this paper (9)
- Intervention effect Root respiration was low under high P regardless of growth stage.
- Intervention effect P deficiency decreased CO 2 assimilation and shoot biomass accumulation.
- Intervention effect P deficiency increased root respiration, root:shoot ratio and specific leaf mass.
- Intervention effect P deficiency increased leaf starch accumulation.
- Intervention effect Daily CO 2 assimilation, shoot biomass, SLM and root:shoot ratio were similar at adequate and high P.
- Association Plant P accumulation increased with P availability.
- Mechanism Reduced root respiration during reproductive transition may indicate roots becoming less competitive sinks than flowers.
- Mechanism Reduced root respiration at high P was attributed to fewer root apices.
- Recommendation The authors conclude that excessive P fertilization is detrimental to root activity in ornamental production.
