Effects of Different Storage Period and Treatment on Seed Germination of Glycine Soja

The seed of wild soybean(Glycine soja) belong to hard seed.Its germination percentage was very low with general methods.The effect on seed germinations and embryo growth by using machinery method of damaging seed coat,freezing,60℃ hot water bath and dryness,lye and soaked in concentrated sulfuric acid and stirred were studied in this paper.The results showed that the germination rate,viability and index with the machinery method of damaging seed coat,sulfuric acid and stirred were higher than that of the control(P0.05).Integrate the experimental results of germination percentage,germination index and seedling growth of wild soybean,the best result was obtained when the seeds were soaked in concentrated sulfuric acid and stirred for 10 min.The germination percentage,germination viability and germination index with freezing treatment were lower than that of the control.Compared with room temperature,thousand seed weight and germination percentage increased under cold storage.The dormancy period of Glycine soja under room temperature and cold storage was 7 and 8 month,respectively.
