摘 要 ：本文较详细地研究了不同地理分布、种子发芽率在35%以上的杉木种子营养化学成分。结果表明,杉木种子中可溶性糖、粗蛋白质、脂肪、淀粉的含量分别为40～70gkg^-1、150～160gkg^-1、230～260gkg^-1、60～80gkg^-1;大量元素含量以N最高,为24～26gkg^-1;微量元素含量依次为Mn>Fe>Zn>Cu>Ni>Pb>Cd。该结果可为杉木种子的品质鉴定提供科学依据。

Abstract:The chemical composition of Chinese fir seeds from different geographic distribution sites and with the germination rate over 35% was studied. The results showed that the content of soluble carbohydrate, coarse protein, fat, and starch in the seeds was 40～70gkg^-1,150～160gkg^-1,230～260gkg^-1,60～80gkg^-1,respectively. The content of N was the highest among the macroelements, wiich was 24～26gkg^-1.The order of the microelement contents in the seeds was Mn>Fe>Zn>Cu>Ni>Pd>Cd. The results may provide a scientific basis for the quality identification of Chinese fir seeds.
