摘要：
A transport velocity of Pu complexed with the siderophore DFOB has been measured in corn to be at least 174 cm/h. Based on a calculated plant water velocity, a Pu retardation factor of 1–10 was estimated. Dominant Pu species retardation in soil is typically several orders of magnitude higher than this, implying that plants can be a vector for exceptionally rapid upward Pu mobility.
