| 摘 要： | 对引进繁育的北美鹋掌楸实生苗的高、地径、叶片宽、叶片长和叶全长等性状进行了调查分析，研究结果表明，该树种在济南地区能健壮生长；种源内及种源闻实生苗高、地径生长量及叶相关性状均表现出较大变异，苗高和叶片长生长量变异达到显著水平，加拿大多伦多种源较为优异；在山东进行引种繁育北美鹅掌楸，需进行种源及个体选择；苗期苗高是进行早期筛选的理想指标。 |

| Abstract: | The height, root diameter, laminae width,laminae length and leaf length of the Liriodendron tulipifera grown in Jinan area during Seedling--period were investigated in this report. The results showed that this species grew well in Jinan; the variances of the growth characters above are greater between and in the provenees and the variance of the height and laminae length is significant between the provences respectively. The provence of Toronto is better. The provences should be selected when this species introduced in Shandong area and the height is a perfect index in the selecting of excellent provence and single tree. |
| Keywords: | Liriodendron tulipifera provence seedlings breeded by the seeds Seedling-- period growth character variance |
