Abstract
The isolated methods as reported previously, were used on Chiba No. 45 (runner type), and various nutrient solutions were added daily to acid- washed sand of the fruiting zone throughout the experiment. 1. Under the conditions of this experiment, fruit development was prevented at the early stage of its development by deficiencies of every element studied. However, production of unfilled fruit was siginificantly increased only on the plants which received the distilled water or minus calcium solution in the fruiting zone. Therefore, it seems that the formation of unfilled fruit result from deficiency of calcium in the fruiting zone, and that the formation of seed is scarcely effected by all the elements except calcium. 2. The analyses at harvest time showed that calcium deficiency had the greatest effect on the contents of HCl soluble calcium in shell and in seed, reducing them from 0.24 and 0.06 to 0.05 and 0.03 percentages respectively. But any element except calcium which was reduced to low content in shell, had scarcely any effect on its content in seed. Magnesium deficiency increased percentage values for alcohol soluble and acetic acid soluble calcium or alcohol soluble potassium in shell. The same tendencies were recognized in the cases both of calcium deficiency and potassium content and of potassium deficiency and magnesium content. Calcium deficiency also had the greatest effect on soluble-N and NO3-N content in shell. The content of non-reducing sugar in shell was remarkably increased in unfilled fruit with abnormal seed. Also the content of starch in abnormal seed was markedly increased. 3. Behaviour of magnesium content, especially acetic acid soluble, during the fruit development made a sharp distinction between calcium deficiency and other deficiencies in this experiment. The same tendency was more clearly found on behaviour of potassium content. Increasing of HCl soluble calcium was hardly observed in the case of calcium deficiency. Nitrogen content, especially NO3-N, in shell of calcium deficiency showed a differential tendency during the fruit development. In case of deficiencies of every element studied, there was little difference between the decreasing tendencies of carbohydrate and phosphorus content.
