为了研究油用牡丹凤丹的籽粒产量和品质性状与不同海拔高度气象因子的相关性，选用油用牡丹凤丹品种为供试材料，在洛阳地区海拔 100~1 010 m的不同样地进行多点栽培试验。结果表明，海拔高度与凤丹籽粒灌浆期和种仁粗脂肪含量呈显著正相关。海拔高度与种仁蛋白质含量呈显著负相关，种仁蛋白质含量与粗脂肪含量呈极显著负相关。海拔高度与凤丹籽粒种仁棕榈酸和饱和脂肪酸相对含量呈显著正相关，种仁亚麻酸和多不饱和脂肪酸相对含量与各气象因子无显著相关性。说明海拔高度影响油用牡丹凤丹籽粒最主要的品质性状是种仁粗脂肪含量。在中高海拔的丘陵山区种植油用牡丹凤丹有利于提高其籽粒百粒质量、出仁率和种仁粗脂肪含量。

 In order to clarify the correlation between the seed yield and quality characters of oil tree peony Fengdan and the meteorological factors at different altitudes,the multi-point cultivation experiments at altitude ranging from 100 m to 1 010 m in Luoyang region was carried out with the tree peony Fengdan as the test material.The results showed that there were significant positive correlations between altitude and the filling stage and the content of crude fat in seed kernel,a significant negative correlation between altitude and protein content of seed kernel,and a significant negative correlation between protein content and crude fat content of seed kernel.Also,there was a significant positive correlation between the altitude and the relative contents of palmitic acid and saturated fatty acid in seed kernel of Fengdan,but there were no significant correlations between the contents of linolenic acid and polyunsaturated fatty acid and meteorological factors.The results revealed that the crude fat content of kernel was the most important seed quality trait of oil tree peony Fengdan affected by altitude.Planting oil tree peony Fengdan in hilly  and mountainous areas at middle and high altitudes is beneficial to increasement of the 100-seed weight,the kernel rate and the crude fat content of kernels．
