Other claims from this paper (12)
- Intervention effect Six nutrient treatments increased unfilled fruit production.
- Observation Shell and seed HCl-soluble calcium distinguished treatment groups during development.
- Intervention effect Young-fruit calcium content was nearly equal among complete, distilled-water and calcium-deficient treatments.
- Mechanism Free citric and malonic acid content declined and accounted for the free-acid reduction.
- Observation Shell free-acid content remained nearly unchanged without calcium.
- Observation Abnormal-seed free-acid content increased during the season without calcium.
- Mechanism Increased malonic acid content mainly caused the abnormal-seed acid increase.
- Association Combined acid content increased in parallel with HCl-soluble calcium in shells.
- Mechanism Oxalic acid content accounted for the increase in combined acid.
- Mechanism Calcium was inferred to combine with oxalic acid in maturing shells.
- Observation Oxalic acid and increasing HCl-soluble calcium were absent under calcium deficiency.
- Observation The same calcium-acid relation was unclear in seeds.
