Movement and Fate of p-Nitrophenyl-α,α,α-Trifluoro-2-Nitro-p Tolyl Ether-1′-14C in Peanut Seedlings

Abstract

Autoradiographs and liquid scintillation counts of peanut (Arachis hypogaea L., var. Starr) seedlings indicate that p-nitrophenyl-α,α,α-trifluoro-2-nitro-p-tolyl ether-1′-¹⁴C (C-6989) is rapidly absorbed from nutrient solution but only 6.5% of the radioactivity absorbed is translocated to the shoot after 144 hr, with the acropetal movement being confined to the stem and petiole.
