In this paper, the assessing indices of container seedlings quality were synthesized in accordance with growth and physiological factors. The results showed that the seedling quality might be determined by the dormancy state of terminal bud, nutrient condition of plant, and the state of root system. The critical quality indices should include stem diameter at soil surface, dry weight of terminal bud, and soluble sugar content. Moreover, some indices such as root system vitality and dry weight of plant were also important.
