Utilization of Organic Compounds by Germinating Soybean Seeds¹

ABSTRACT

Surface-sterilized soybean seeds (Glycine max L.) were placed inside sterile vials containing 5 ml of sterile, deionized water and 1µCi amounts of various ¹⁴C-labeled organic compounds. The atmosphere inside the sealed vials was analyzed for ¹⁴CO₂ every hour for 12 hours. The compounds tested were uniformly labeled glucose, fructose, maltose, lysine, glycerol, and urea; glycine labeled in the 1 or the 2 position; and citric acid labeled in the 1 and 5 positions. All compounds tested were metabolized by germinating soybean seeds as evidenced by ¹⁴CO₂ evolution. However, with the exception of urea, the amount of ¹⁴CO₂ produced was small. Urea was metabolized very rapidly and very extensively. It appears that soybean seeds can metabolize external organic molecules within 1 hour of exposure to moisture.
