Abstract

Petiolar application of potassium cyanide inhibited 14C-assimilate translocation without affecting source leaf photosynthesis or phloem loading of sucrose inPhaseolus vulgaris. The inhibition of transport was correlated with disruption of the structural integrity of the sieve tubes (sieve pore blockage) rather than impairment of a metabolic process in the translocation path driving translocation.
