Flux of 14C-labelled carbon from plants to hyphae of AM fungi for 70 h post-labelling was measured by (a) trapping CO2 released from soil cores containing AM hyphae linked to the plants compared to cores from which AM hyphal connections to the plant roots had been severed, and (b) quantification of the total amount of 14C in the cores. Release of 14CO2 from the cores colonised by active AM mycelium was highest for 0–28 h from the onset of labelling and declined rapidly thereafter.
