Other claims from this paper (11)
- Association Boron concentrations in shoots and roots increased strongly up to 1–2 μM external B and more weakly above 2 μM.
- Observation Petioles retained unchanged B concentration from day 22 to day 55 in most treatments.
- Association With higher external B, relative B content increased in leaf blades.
- Association With higher external B, relative B content decreased in roots.
- Association With higher external B, relative B content generally remained unchanged in stems and petioles.
- Observation Plants at low external B maintained vegetative growth but failed to produce reproductive parts.
- Observation Florets had the maximum B concentration at flowering.
- Intervention effect Low B depressed floret growth more sensitively than vegetative parts.
- Intervention effect At ≤ 0.41 μM external B, reproductive growth was depressed relative to ≥ 0.86 μM.
- Intervention effect Low external B delayed flowering by 6–8 days.
- Observation At low external B, flowers aborted soon after bud burst.
