摘　　要：笔者从运城市绛县磨里镇郭家庄村、临汾市翼城县西闫镇和晋城市沁水县土沃乡3个种源区采集种子,分别在运城市绛县陈村、临汾市翼城县十里河镇、晋城市沁水县中村镇进行白皮松种源选育试验。结果表明,种源区1的白皮松种子千粒重均大于140 g,明显高于其他2个种源;其发芽率均大于85%,也明显高于其他2个种源。种源区1的白皮松2年生苗木、5年生苗木的苗高、地径、主根长、成活率均高于其他2个种源,10年生苗木、15年生苗木的苗高(树高)、地径(胸径)也高于其他2个种源。因此,运城市绛县磨里种源为白皮松优良种源,可以进行推广栽植。Seeds were collected from 3 provenances which were Guojiazhuang Village in Moli Town of Jiang County in Yuncheng City,Xiyan Town in Yicheng County of Linfen City and Tuwo Township in Qinshui County of Jincheng City.Provenances selection experiments of Pinus bungeana were conducted in Guochen Village of Moli Town in Jiang County of Yuncheng City,Shilihe Town of Yicheng County in Linfen City and Zhongcun Town of Qinshui County in Jincheng City.Results showed that the thousand seed weight of Pinus bungeana seeds in provenance area 1 was greater than 140 g which was significantly higher than the other 2 provenances,the germination rates was greater than 85%which was significantly higher than the other 2 provenances.The seedling height,ground diameter,root length and survival rate of 2-year-old and 5-year Pinus bungeana seedlings in provenance area 1 were higher than those in the other 2 provenances.The seedling height(tree height),ground diameter(DBH)of 10-year-old and 15-year Pinus bungeana seedlings in provenance area 1 were higher than those in the other 2 provenances.Therefore,Moli Town of Jiang County in Yuncheng City was an excellent provenance of Pinus bungeana and could be promoted for planting.
