采用随机区组试验设计,于2005年春,将来自甘肃天水和两当、陕西蓝田、山西孝义和北京等5个白皮松种源的幼苗分别在北京十三陵林场和河南卢氏东湾林场进行种源试验。通过对其2008年和2011年保存及生长状况进行分析,结果表明:白皮松各种源在河南卢氏保存率较高,而在北京生长较快。种源内各家系在两地均能完整保存,家系和单株保存率依次为:北京(92.66%、59.01%)、孝义(91.21%、57.24%)、蓝田(85.28%、53.39%)、天水(81.44%、49.56%)和两当(80.83%、42.26%)。白皮松树高生长较快的是天水种源(100.09cm),然后依次是两当(93.66cm)、蓝田(91.23cm)、北京(87.53cm)和孝义(82.06)种源。
In the spring of 2005, seedlings from five provenances of Pinus bungeana from Tianshui and Liangdang in Gansu Province, Lantian in Shaanxi Province, Xiaoyi in Shanxi Province, and Beijing were respectively planted in the Shiminling Forest Farm in Beijing and the Ludong Dongwan Forest Farm in Henan Province Provenance test. According to the analysis of their conservation and growth status in 2008 and 2011, the results showed that all the Pinus bungeana sources had a higher preservation rate in Henan and faster growth in Beijing. The genealogical families within each provenance can be completely preserved in both loci. The conservation rates of pedigree and single plant were as follows: Beijing (92.66%, 59.01%), Xiaoyi (91.21%, 57.24%), Lantian (85.28%, 53.39% Tianshui (81.44%, 49.56%) and two when (80.83%, 42.26%). The high growth of Pinus bungeana was the provenance of Tianshui (100.09cm), followed by the provenance of 93.66cm, Lantian (91.23cm), Beijing (87.53cm) and Xiaoyi (82.06).
