Organic Substance Metabolism in Seeds of Sophora japonica during Germination

摘要

The metabolism of fats, proteins and carbohydrates and the change of enzyme activity in seeds of Sophora japonica during germination were studied by methods of Soxhlct's extraction, flow injection and colorimetric analysis of spectrophotometcr for providing theoretical basis for germination and storage of seeds of forest trees. The results are as follows: (1) The activity of enzymes in the seeds does not always coincide with the increase or decrease of their corresponding substances during germination of the seeds of Sophora japonica. (2) Proteins were first utilized during germination of the seeds. (3) The fatty acids reducing sugar and amino acids in the radicle+plumular axis were used psecedcntly over all others when the embryos grew. (4) excessive small—molecular substances produced by hydrolysis would accumulate in tissrcs and sometimes they were stored temporarily in the form of storage substances and finally used for embryo growth.
