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.
