There were 2 peaks of starch accumulation in the process of somatic embryogenesis,the first time was at the stage of embryogenic callus,the second time was at the stage of globular embryoids;and a small raise appeared at the stage of torpedo-shaped embryoids,and the content of starch was slightly higher than those of heart-shaped embryoids and cotyledonary embryoids.With the development of embryos,the tendency of the changes of the content of DNA,RNA and the total nucleic acids was approximately similar,and the peak values were all at the stage of cotyledonary embryoids,and the change of the content of RNA was more remarkable than those of DNA and the total nucleic acids.The tendency of change of the content of proteins almost took on the S-shaped curve.
