Within three hours after application, radioactive material was found in the treated leaf, root and 33 Analytical Determination of Nicotine leaves younger than the treated leaf, but in not older leaves. 13% of the initial radioactivity. Even though the amount of radioactivity in the root was small compared to the total JA applied, it was yet commensurate with the increment of root JA observed after wounding. JA-conjugate pools, measured using several different hydrolysis procedures, amounted to only about 10% of the free JA pool, insufficient to account for the ten-fold increase of JA in the shoot 90 min post-wounding .
