Studies were made on the relationship between respiration rate and nitrogen concentration of trees (mainly Plnus densiflora), in the correlations found in various organs (i.e. needle, branch, stem) and the seasonal variations. The respiration rate differed greatly between the photosynthetic and nonphotosynthetic organs. However, when the respiration rate of these organs was comnared on a unit nitrogen concentration basis, the difference was smaller. That is, the respiration tended to increase with higher nitrogen content. The same relation existed in differnt kinds of tree leaves. The respiration rates of current needles and branches, calculated at 20℃, showed the minimum values in summer and the maximum in winter, and those of 1-year-old needles and branches showed smaller seasonal variations. The seasonal variations in nitrogen concentration showed a concave trend in common with respiration rates.
