By Ryan, Elizabeth A. Source University of Aberdeen (United Kingdom) Published 1993 Indexed 2023-05-21 Document Type Dissertation/Thesis Abstract On poor peats and heathlands, satisfactory growth of Sitka spruce (Picea sitchensis), planted pure, can only be achieved with repeated applications of nitrogen fertilizer. However, when spruce is planted in mixture with Scots pine (Pinus sylvestris), Lodgepole pine (P.contorta), or Japanese larch (Larix kaempferi) it shows improved nitrogen nutrition and better growth than pure spruce. The mechanism by which the 'extra' nitrogen required to sustain improved spruce growth has not yet been elucidated. A mechanism is proposed in this thesis. The mycorrhizal community is examined in pure and mixed stands at Culloden Scotland, by recording potential mycorrhizal fruiting bodies, carrying out a seedling bioassay and characterising the mycorrhizal communities on both pine and spruce roots. |
