| 【目的】筛选优良的白皮松种源和家系，以提高北京市白皮松绿化和造林的质量。【方法】以来自甘肃天水、陕西洛南、甘肃两当、陕西蓝田、山西孝义的5个种源各30个家系的白皮松为研究材料，以北京蟒山的30个白皮松家系为对照，采用完全随机设计，测定4年生白皮松苗的苗高和地径，在北京地区开展种源和家系对比试验。【结果】不同种源间4年生白皮松的苗高和地径生长量差异极显著，其中北京当地对照白皮松表现处于中下水平，而甘肃两当和甘肃天水2个种源白皮松表现较好，苗高和地径生长量较大；白皮松种源内不同家系间的生长量也具有极显著差异，甘肃两当、甘肃天水、陕西蓝田、山西孝义及北京蟒山种源中，白皮松苗高和地径生长均超过对照种源家系均值的家系数分别为23，23，10，10和10个，苗高和地径生长量超过对照平均水平的家系主要来自甘肃两当和甘肃天水地区。【结论】甘肃两当和天水是今后北京地区造林和绿化用白皮松优先考虑的种源地。 |

| Abstract: |
| 【Objective】This study selected elite provenances and families of Pinus bungeana to improve the quality of landscaping and afforestation in Beijing.【Method】Seeds of P.bungeana from 5 provenances (GSTS,SXLN,GSLD,SXLT and SXXY) with 30 families each were compared with seeds of 30 families from BJMS.Seedlings were planted in field comparison test with randomized design.Heights and basal diameters of 4-year old seedlings were determined and compared.【Result】There were highly significant differences in height and basal diameter of 4-year old P.bungeana seedlings of among provenances.Seedlings from BJMS were in relatively low level,while seedlings from GSLD and GSTS had better performance.There were also highly significant differences among different families of each individual provenance.The numbers of families with better height and basal diameter growth than CK in GSLD,GSTS,SXLT,SXXY and BJMS were 23,23,10,10 and 10,respectively.Superior families mainly originated from GSLD and GSTS.【Conclusion】P.bungeana from GSLD and GSTS should have priority for landscaping and afforestation in Beijing. |
