Abstract:This paper studied that the significant difference exists among the ten provenances of 9-year-oldFraxinus mandshurica stand. The rule of geographic variation is that dual continuous changes with longitude and latitude, and the provenance in the southwest range grows rapidly. There are positive significant correlation when the tree growth is influenced by ≥10°C accumulated temperature, duration of sunshine and annual precipitation. So it is suggested that Lushuihe and Maoershan provenances should be employed first in Maoershan Forest Farm and its neighborhoods. (Responsible Editor: Zhu Hong)
