- Abstract:
- We have shown that the dominant ericoid mycorrhiza of British heathland Systems, Hymenoscyphus ericae, has considerable intraspecific variation in its preference for nitrogen sources (ammonium, nitrate & amino acids). This raises the question as to why this variation is present. We wish to test the hypothesis that intraspecific variation in N source utilisation by the fungus enables the association to maximise exploitation of N source(s) available. This project aims specifically at assessing whether difference in N preference of H. ericae isolates will infer variability in N assimilation by the association Vaccinium myrtillus/H. ericae. This will be tested using a factorial experiment comparing N uptake of seedlings mycorrhizal-free or infected with strain of H. ericae of contrasting preference, supplied with different forms of 15N labelled N.
