Table 1 Total 15N recovery in the labelling systems and in pea plant parts supplied with the labelling solutions as well as in triticale plant parts as intercrop at the end of a 105-day greenhouse pot experiment; transfer paths: ADR = AMF, diffusion, and root contact between pea and intercrop; AD = AMF and diffusion; A = only AMF; CV = mean coefficient of variation between replicate pots (n = 6).
