Cabbage plants were grown at graded levels of nitrate nitrogen (20 and 100 ppm N) and temperature (15, 20, and 25℃), and the effects of these treatments on cabbage-head development were investigated. The total plant dry weight and the cabbage-head yield were always higher at 100 ppm N than at 20 ppm N, and at each N level the values were in the order of 20>15>25℃. The nitrogen content in the outer leaves was higher at 100 ppm N than at 20 ppm N, and increased slightly with increase in temperature. The total sugar content was higher in the inner head leaves, and was decreased greatly at 25℃ in both organs. The ^<14>CO_2 assimilation of the outer leaves, and was decreased greatly at 25℃ in both organs. The ^<14>CO_2 assimilation of the outer leaves was larger at 100 ppm N than at 20 ppm N. After ^<14>CO_2 assimilation by the plants, a greater amount of ^<14>C was lost by respiration at 25℃ than at 15 and 20℃, resulting in a low distribution of ^<14>C-sugars in the inner head leaves. The highest yield and a better quality of cabbage-heads were obtained when the plants were grown at 20℃ with a high N supply and the outer leaves had a carbohydrate/nitrogen content ratio of about 7.
