Abstract


KIM, JOON HO (Dept. of Biology, Kongju Teacher´s College) Effects of Urea Nitrogen on the Metabolism of Plants Ⅳ. On the change of simple sugar content in plants treated with nitrogen. Kor. Jour. Bot. Ⅶ (1):11-14, 1864.
Change of the amount of carbohydrates in relations with nitrogen metabolism was studied under the different manners of supply and with different sources of nitrogen. In barley plant supplied with nitrogen through root, the depression periods of glucose and sucrose content occurred at 2 days after, but the amounts of both sugars were different with the different sources of nitrogen; there were in sequence diminished by treatement of NO_3, NH_4 and urea.
In sunflower leaves sprayed with urea both sugar contents were inversely related to the urea concentration speayed, and depressing periods of the sugars appeared immediately in the N-deficient plant but late in the N-abudant one.
