This paper concerned the application of improvement in Vivo of Traditional Method for determination of nitrate reductase (NR) activity of leaves to dominant tree species in five forest communities of northern aspect of Changbai Mountain. The results indicated that the NR activity of tree species was related to shade tolerance, and the intolerant tree species had higher NR activity. The NR of a species was also related to the vertical structure and ecological site condition. The tree species, which have higher NR activities should be selected for fast growing and high yield tree species.
