Abstract
The behavior of calcium in Chiba 74 (runner type) in process of growth and maturity was observed using radiocalcium as a tracer and the effects of calcium deficiency upon chemical composition of it were examined. Roots were grown in gravel culture and they received Ca deficient nutrient solution both after the early stage of growth and flowering stage, while fruits were grown in sand culture with a complete solution until harvest. 0.5 1. of the complete solution including 0.5 mc. of Ca45 Cl2 was supplied to the rooting medium of each plant for 5 days at the three stages of growth. 1. Top growth, flower production, peg and pod formation were hindered significantly by deficiency of Ca after early stage of growth, but plants, which received no Ca after flowering, were not prevented from their flowering and peg or pod formation. 2. The greater part of Ca45, irrespective of its date of supplying, was found to accumulate in the vigorus leaf during the time of the treament with Ca45, and maximum distribution of Ca45 in the leaf never changed till their harvest times, even in the case of withholding Ca from the plants after Ca45 treatment. The distribution of Ca45 was observed mainly in the terminal part at the lateral branch of all the plants, except the control plant which was treated by Ca45 at the early stage of growth, and in the root, accumulation of Ca45 was remarkably decreased at the early stage of growth. Through the whole stage of growth less distribution of Ca45 was observed in the fruit, which involed more Ca45 when it was supplied at flowering stage than when it was supplied at vegetative stage. 3. Ca contents of various parts of plant except the fruit were remarkably decreased by deficiency of Ca after the vegetative stage. On the other hand, it was recognized that no great difference in Ca contents was made between the plant withheld Ca after flowering and the one supplied with the complete solution. The inverse relations, which were caused by the deficiency of Ca after early stage of growth, were found to exist between the following chemical composition; between starch and Ca contents in each organ of the plant, except in the root; between K and Ca in the leaf; between Mg and Ca in the lateral branch and in the root. On the contrary at flowering stage the inverse relation between Ca and other chemical compositions was less distinct in each organ of the plant.
