摘　　要：对油松、侧柏苗木形态与生理之间关系的研究表明：在正常生长情况下，苗木形态特征是苗木生理状况的外在表现。同一批苗木内，苗木形体越大，则针叶内Ｎ，Ｐ，Ｋ浓度越高，总含量越大，并且叶绿素含量和净光和速率也越高，因此苗木形态在一定程度上反映了苗木质量。The relationship of seedling morphology and physiology were studied on Pinustabulaeformis, Platycladus orientalis,Larix prineipis-repperehtii and Pinus sylvestris L. var. mongOlica in northern China. The results demonstrated that seedling morphology,innormal growth conditions,is an indicator of physiological status because morphological fea-tures such as height and diameter are correlated with seedling needle N,P,K concentrations,chlorophyll contents and the rate of photosynthesis.
