Abstract: This paper summarises the recent determinations in respiration of branch, stem and root of Korean pine in natural forests of Changbai Mountain. Patterns of their diurnal variations are similar. The peaks for branch,stem and root are respectively 2.25,3.36 and 0.92μmol.s-1.m-2at 12-16 o'clock.The variation of their respiration rate is closely related with ambient temperature.Q10 value ranges from 1.5 to 3 for stem,and from 2.5 to 4 for root.

Key words: Korean pine, Non-photosynthetic organ, Respitation rate
