樟子松１４个种源（产地）试验的研究表明，樟子松苗期生长与原产地纬度、海拔高及降水量、年均气温存在着密切的相关性，相关系数分别为－０５４７５、－０６６１９和０６２２１、０６５５３。６年生幼树种源间高生长差异达到１％的显著水平。物候期观测结果，不同种源生长节律不同，纬度较高的种源的物候期到来较早，纬度较低的到来略迟，相差１～４天。不同种源造林成活率、幼树保存率及抗虫性不同，９００７号（净月潭）、９０１４号（章古台）种源造林成活率、幼树保存率较高，抗虫性以９０１４号和９０１２号（青山）最强。
Studies on 14 provenances (provenances) of Pinus sylvestris var. Mongolica showed that there was close correlation between the growth of Pinus sylvestris var. Mongolica and the latitude, altitude, precipitation and average annual temperature of origin, the correlation coefficients were -0.5475, -0.66619 and 0 6221,065 653. 6-year-old saplings of high-growth difference between the significant level of 1%. Phenological observation results showed that different provenances had different rhythms of growth. Earlier phenology of germplasm with higher latitudes came earlier and latitude was slightly delayed with a difference of 1 to 4 days. The survival rate of different provenances, sapling rate and pest resistance were different, 9007 (Jingyuetan), 9014 (Zhanggutai) afforestation survival rate, the sapling preservation rate higher resistance to 9014 No. 9012 (Aoyama) the strongest.
