Abstract: | The metabolism of fats, proteins and carbohydrates and change of enzyme of seeds ofpinus bungeana during the germination were conducted by the methods of gas-liquid chromatography, flow injection, colorimetric analysis
of spectrophotometer, to provide theoretical basis for seeds dormancy, germination and storage of seeds of forest tree. The
results indicate that (1) carbohydrates were first utilized during germination of seed ofpinus bungeana; (2) stored substances in seeds began to decompose quickly after radicale broke through seed coats; (3) the activity of enzymes
in the seeds does not always coincides with the increase or decrease in quantity of its responsible substance during germination
of the seed. Changes in stored substance relate to metabalism of other metabolism of other materials and the use of hydrolysates. |
