- Intervention effect Calcium deficiency after early growth significantly hindered top growth, flower production, and peg and pod formation.
- Intervention effect Withholding calcium after flowering did not prevent flowering or peg and pod formation.
- Observation Most applied Ca45 accumulated in vigorous leaves during treatment and remained most concentrated there until harvest.
- Observation Ca45 was mainly distributed in the terminal part of lateral branches, with a stated control exception.
- Observation Root Ca45 accumulation decreased markedly at the early growth stage.
- Observation Fruit had less Ca45 distribution throughout growth than other plant parts.
- Intervention effect Fruit contained more Ca45 when supplied at flowering than when supplied in the vegetative stage.
- Intervention effect Calcium deficiency after the vegetative stage markedly decreased calcium contents outside the fruit.
- Intervention effect Calcium contents differed little between plants deprived of calcium after flowering and those receiving complete solution.
- Association After early calcium deficiency, starch and calcium contents were inversely related in organs other than roots.
- Association After early calcium deficiency, magnesium and calcium contents were inversely related in lateral branches and roots.
- Association At flowering, inverse relations between calcium and other composition measures were less distinct across organs.
