Optimising ectomycorrhiza development in the containerzised nursery
Hardy, G., Burgess, T. and Dell, B. (2004) Optimising ectomycorrhiza development in the containerzised nursery. In: IV Asia-Pacific Mycological Congress & The IX International Marine and Freshwater Mycology Symposium, 14 - 19 November, Chiang Mai Thailand.
Conditions for optimal mycorrhiza formation were studied in a commercial nursery using seedlings and inoculum of six compatible ectomycorrhizal (ECM) fungi. Factors evaluated were type and preparation of the potting mix, mineral nutrition of the host, and chemical control of pathogens. Mycorrhization was reduced by the use of poorly composted sawdust/pinebark, non-pasteurised substrates, the use of soluble ' ystemic' ti high in available N and P. Optimal mycorrhiza development occurred in either a peat/perlite substrate or in well composted eucalypt bark potting mix supplemented with low N and P nutrients. The use of a range of fungicides routinely used to control damping-off and foliar pathogens in production nurseries had no impact on mycorrhizal development. Well inoculated plants had more than 80% of their root system by ECM fungi.
