In order to understand the mechanism of the wide occurrence of tipburn phenomenon in Chinese cabbage grown under protected cultivation, Chinese cabbage cultivated in two experimental plots was analyzed based on the distribution of some mineral elements by region in the plant and in the soil. The following results were obtained : 1) The occurrence of tipburn is not related to the concentration of Ca in the soil. 2) The concentration of Ca by region in the plant increased in the order such as inner leaf < middle leaf < outer leaf and inner vein < middle vein < outer vein. 3) From this results the cause of occurrence of tipburn phenomenon in Chinese cabbage which occurred at fixed times in the growth and development of the plant can be controlled by modifying environmental factors in order to prevent excessive transpiration in the inner leaf.
