摘　　要：对济源、洛阳、三门峡3个不同分布区的毛梾果实和种子的形态特征及脂肪油进行了测定分析。结果表明:(1)3个分布区毛梾果实的纵径、横径和百果质量均有极显著差异,且均为济源>三门峡>洛阳。(2)毛梾果实中的粗脂肪含量高于种子,说明其果皮中含有较高的粗脂肪,且不同产地的毛梾果实及种子之间粗脂肪含量存在显著差异,果实的粗脂肪含量由高到低依次为济源>三门峡>洛阳。(3)毛梾果油中的脂肪酸组成主要为二十碳链以下的直链脂肪酸,主要是十六碳和十八碳的脂肪酸,组成成分简单而且集中,但酸值较高,对其后续的生产加工将造成一定的影响,因此,培育低酸值的毛梾品种意义重大。毛梾果油含有大量的亚油酸,也可作为食用油原料加以利用。The content of the fruit fattyoil and the fruit morphology and oil length of Cornus walteri in Jiyuan,Luoyang and Sanmenxia were tested and analyzed.The result showed： Fistly,there were significant difference among the longitudinal diameter,diameter and the hundred fruit weight of the Cornus walteri in the three distribution areas,which were in an order of Jiyuan Sanmenxia Luoyang;Secondly,the crude fat content in the fruit were higher than in the seeds,which suggested that there were higher crude fat in the fruit peel and there were significant difference between the fruit crude fat content and the seeds in these three distributions.Whether it was the fruit or the seed,their crude fat contents were from high to low all in an order of Jiyuan Sanmenxia Luoyang;Thirdly,the fatty acid composition in fruit oil of Cornus walteri was the straight-chain fatty acids no more than twenty-carbon chain that mainly were sixteen-or eighteen-carbon fatty acid.They are suitable to be used as raw material of bio-diesel,but the high acid which would affect the process.Therefore,it is of great importance to select low acid cultivar in Cornus walteri breeding.There is great deal linoleic acid in the cornus walteri fruit oil,which could be used as raw material to the edible oil.
