ORGANIC SUBSTANCE METABOLISM DURING SEED GERMINATION OF PINUS BUNGEANA

The metabolism of fats,proteins and carbohydrates and change of enzyme ofseeds of pinus bungeana during the germination were conducted by the methods of gas-—liquid chromatography,flow injection,colorimetric analysis of spectrophotometer,toprovide theoretical basis for seeds dormancy,germination and storage of seeds of foresttree.The results indicate that(1)carbohydrates were first utilized during germination ofseed of pinus bungeana;(2)stored substances in seeds began to decompose quickly afterradicale broke through seed coats;(3)the activity of enzymes in the seeds does not alwayscoincides with the increase or decrease in quantity of its responsible substance duringgermination of the seed.Changes in stored substance relate to metabalism of othermetabolism of other materials and the use of hydrolysates.
