Other claims from this paper (15)
- Intervention effect Root P concentration increased with solution P.
- Intervention effect Root phytate P was greater at 6 mM P than at 0, 1, or 2 mM P.
- Intervention effect At 0 mM P, shoot mass was 67% lower than at 6 mM P.
- Intervention effect At 0 mM P, shoots per plant were 43% lower than at 6 mM P.
- Intervention effect Root starch and protein concentrations did not decline after defoliation at 0 mM P.
- Intervention effect Defoliation increased root endoamylase activity in plants receiving P.
- Association Root total amylase activity declined as P supply increased.
- Association Root total amylase activity was not associated with root starch degradation.
- Intervention effect Root P concentration rose within seven days of P application.
- Intervention effect P applied at defoliation enhanced root starch use.
- Intervention effect P applied on day 14 had no effect on root starch depletion.
- Observation Plants supplied 6 mM P used root starch normally after a second defoliation.
- Intervention effect P application during regrowth did not restore normal root protein utilization.
- Observation P deficient roots retained high organic reserve concentrations but impaired use after defoliation.
- Observation P deficient roots had impaired reserve use after defoliation.
