摘　　要：对大叶樟、猴欢喜、木莲3种容器苗的多个形态指标进行测定,并研究其根系水势和根生长潜力的关系,结果表明,容器苗地径和全苗干重与各形态指标间显著相关,是反映容器苗质量的重要形态指标;苗木根系水势和根生长潜力回归极显著,是苗木质量评价重要的生理指标和活力指标。Determination was carried out on morphological indicators of container seedlings of Cinnamomum platyphyllum, Manglietia fordiana, Sloanea sinensis to study relations between water potential of root system and root growth potential. The results demonstrated that the critical morphological quality indicators should include stem diameter and the dry weight of whole seedlings. Root water potential and root growth potential had strongly correlated, and should be considered as the main indicators for physiological and vigor.
