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.
