Absorption and translocation of carbon from 14C-labelled urea applied to leaves and roots

, : Absorption and translocation of carbon from 14C-labelled urea applied to leaves and roots. Roczniki Nauk Rolniczych, A 100(2): 7-15

In laboratory trials in a closed water culture system in which the root systems could be separated from the stems and leaves, translocation of 14C was determined 6, 24 and 48 h after supplying beans (Phaseolus vulgaris) with 14C-urea. 6 h after foliar application of urea, concentration of 14C was 3.2 times higher in the leaves and 1.7 times higher in the stems than in the roots.
