Other claims from this paper (7)
- Association Roots of the susceptible sunflower genotype appear more sensitive to low B contents in the solution than shoots.
- Association The shoot/root dry-weight ratio of sunflower was smaller in the resistant genotype.
- Observation B contents in the water-insoluble residue of sunflower roots were similar for all genotypes and treatments.
- Association B concentration in leaf water-insoluble residue of sunflower reached near-saturation values only once B accumulated in root cell sap.
- Mechanism Critical shoot B concentrations in sunflower are established after the cell-wall B requirement is satisfied and a proper metabolic B content in root cell sap is reached.
- Mechanism Low uptake efficiency at high B supply suggests an exclusion mechanism that restricts B accumulation in sunflower.
- Mechanism High uptake efficiency with low-B treatments indicates mechanisms other than mass flow supply the acquired B in sunflower.
