摘　　要：为了探讨嫁接砧木对红松结实及其松籽品质的影响,采用樟子松嫁接红松技术,把辽宁本溪、黑龙江尚志等地红松品种引种到陕西榆林,并对嫁接8 a~10 a后的植株果实(松籽)的营养成分进行了分析评价。研究结果表明:(1)矿物质营养元素含量方面,11种矿质元素中来自榆林两个样品的8种矿质元素显著高于来自东北地区的样品;(2)碳水化合物组成方面,各样品间淀粉含量无显著差别,榆林地区样品的可溶性糖含量显著高于东北地区,而粗蛋白质、粗脂肪含量则是显著低于东北地区样品;(3)氨基酸组成方面,榆林人工林样品中的总氨基酸、必需氨基酸、鲜味氨基酸、药效氨基酸等含量均显著高于其他样品;(4)脂肪酸组成含量方面各处理间差异均未达到统计学显著水平。主成分分析结果表明,来自榆林人工林的样品得分最高,黑龙江人工林次之,榆林苗圃地样品排名第四。To investigate the impact of grafting stock on the fruiting of Pinus koraiensis and the quality of its pine nuts,the technique of grafting Korean pine onto Pinus sylvestris var.mongolica was applied to introduce varieties of Pinus koraiensis from Benxi of Liaoning,and Shangzhi of Heilongjiang,to Yulin of Shaanxi,and the nutritional components of the pine nuts of the grafted plants from 8 a to 10a after grafting were analyzed and evaluated.The research showed that:(1)In terms of the content of mineral nutrient elements,among the 11 compared mineral elements,8 mineral elements from the two samples in Yulin were significantly higher than those from the samples in the Northeast region;(2)Regarding carbohydrate composition,there was no significant difference in starch content among the samples.The soluble sugar content of the samples from Yulin region was significantly higher than that in the Northeast region,while the contents of crude protein and crude fat were significantly lower than those of the samples from the Northeast region;(3)In terms of amino acid groups,the contents of total amino acids,essential amino acids,umami amino acids,and medicinal amino acids in the samples from the artificial forest in Yulin were significantly higher than those of other samples;(4)No statistically significant differences were observed in fatty acid composition and content among the different treatments.The results of principal component analysis show that the samples from the Yulin plantations scored the highest,followed by those from the Heilongjiang plantations,and the samples from the Yulin nurseries ranked fourth.
