Very little sugar was translocated to the primary leaf opposite the treated petiole or to the growing tip of the stem. Of the small amount of sugar that was translocated upward the bulk accumulated in the younger rather than the older trifoliate leaf. When glucose-C 14 or fructose-C 14 were used the radioactivity in the stem decreased logarithmically from the point of introduction. The downward translocation of both sugars was impeded at the nodes.

These hexoses were translocated both upward and downward past killed sections of stems. When sucrose-C 14 was used the radioactivity in the stem decreased linearly from the point of introduction. Sucrose was not translocated either upward or downward past killed sections of stems.

This rapid cell division requires a large amount of fuel, and that fuel is the sugar in our body. However, postings on the Internet have created misleading and inaccurate conclusions about the relationship between cancer and sugar intake.

A radioactive form of glucose (sugar) often used during a positive emission tomography (PET) scan, a type of imaging test. In PET, a small amount of radioactive. The radioactive sugar can help in locating a tumor, because cancer cells take up or absorb sugar more avidly than other tissues in the body.
