摘　　要：在全国5省(区)收集桢楠15个种源71株优良单株种子,采用容器育苗方式,随机区组设计3次重复,对不同种源苗木的苗高、地径、地上生物量和地下生物量等指标进行了研究。结果表明,不同种源间苗高和地径差异显著;不同种源苗木单株生物量及地下/地上差异较大;经综合评价,以种源7、10、1、2和4表现较优。The seeds of Phoebe zhennan collected from 71 superior individual plants of 15 provenances were sowed by way of container seedling raising. Research work was designed by random blocks and repeated 3 times. Such indexes of different provenances as the height,ground diameter,aboveground biomass and underground biomass of seedlings were studied through variance analysis and multiple comparison method. The results indicated that the seedling height and ground diameter growth of different provenances had a significant difference. There was great difference in individual biomass and the biomass ratio between the underground part and the aboveground part of the different provenances. Through comprehensive evaluation,provenances 7,10,1,2 and 4 performed excellently.
