不同采种地点核桃楸种子形态及苗期生长指标的观测结果表明：江源的种子小，苗木生长量低，苗木生长变异系数大；磐石的种子较大，差异性小，出苗率高，苗高性状差异小，生长良好，且呈稳定增长趋势。所有采种地点的苗木地茎均无明显差异。综合不同采种地点的种子形态和苗期生长表现，磐石采种点的种子优于其他7个采种点，适合作优良种子使用。
不同採種地點覈桃楸種子形態及苗期生長指標的觀測結果錶明：江源的種子小，苗木生長量低，苗木生長變異繫數大；磐石的種子較大，差異性小，齣苗率高，苗高性狀差異小，生長良好，且呈穩定增長趨勢。所有採種地點的苗木地莖均無明顯差異。綜閤不同採種地點的種子形態和苗期生長錶現，磐石採種點的種子優于其他7箇採種點，適閤作優良種子使用。

The observation result of seed morphology and seedling growth of Juglans mandshurica from different regions showed that the seeds of Jiangyuan were small, the growth increment of nursery stock was low, the variable coefficient of nursery stock growth was large.Furthermore, the seeds of Panshi were larger, the difference was small, the rate of emer-gence was high, height of seedling properties difference was small, the growth was fine and it presented the tendency of steady increase.The seedling stem of all seed collecting area had no evident difference.The seeds of Panshi seed collecting area were superior to other 7 seed collecting area after synthesizing the seed morphology and seedling growth of different are-a.It was suitable for the usage of high quality seeds.
