摘要: 树木的呼吸作用是能量消耗与转换的过程,它将有机物质氧化成为二氧化碳和水,释放出能量以供生长和维持生命活动所需。研究树木呼吸作用的意义不仅在于它与环境因素及生长节律紧密相关,而且也是在建立碳平衡模式中不可缺少的组分。由于对呼吸的研究不够充分,这一组分目前仍是个空缺。

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
