Other claims from this paper (9)
- Intervention effect At initiation of flowering, plants exposed to reduced R:FR had greater specific leaf area, stem elongation and main stem leaf area than plants under ambient R:FR.
- Intervention effect At initiation of flowering, plants exposed to reduced R:FR had greater specific stem length and main stem mass than plants under ambient R:FR.
- Intervention effect Biomass allocation to stems, leaves and roots did not differ between vegetative-stage R:FR treatments.
- Intervention effect At the end of flowering, morphology and productivity of plants in partial shade did not differ between vegetative-stage R:FR treatments.
- Intervention effect Plants in full sunlight during flowering after reduced vegetative-stage R:FR had less total plant mass and less total leaf area than plants given ambient R:FR.
- Intervention effect Plants in full sunlight during flowering after reduced vegetative-stage R:FR had greater stem elongation, specific stem length and ratio of main stem to total stem mass than plants given ambient R:FR.
- Intervention effect At physiological maturity, plants given reduced vegetative-stage R:FR and partial shade in the reproductive stage had less total seed mass and fewer seeds than plants given ambient R:FR and partial shade.
- Intervention effect Fecundity of plants in full sunlight during the reproductive stage did not differ between vegetative-stage R:FR treatments.
- Intervention effect The authors interpret reduced vegetative-stage R:FR as maladaptive at later growth stages of common lambsquarters in competitive environments.
