| Abstract/Contents: | "Plantago lanceolata L. and Trifolium repens L. were grown for 16 wk in ambient (360 Ī¼mol molā»Ā¹) and elevated (610 Ī¼mol molā»Ā¹) 1 atmospheric COā. Plants were inoculated with the arbuscular mycorrhizal (AM) fungus Glomus mossea (Nicol. & Gerd.) Gerdemann & Trappe and given a phosphorus supply in the form of bonemeal, which would not be immediately available to the plants. Seven sequential harvests were taken to determine whether the effect of elevated COā on mycorrhizal colonization was independent of the effect of COā on plant growth. Plant growth analysis showed that both species grew faster in elevated COā and that P. lanceolata had increased carbon growth allocation towards the roots. Elevated COā did not affect the percentage of root length colonized (RLC); although total colonized root length was greater, when plant size was taken into account this this effect disappeared. This finding was also true for root length colonized by arbuscules. No COā effect was found on hyphal density (colonization intensity) in roots. The P content of plants was increased at elevated COā, although both shoot and root tissue P concentration were unchanged. This was again as a result of bigger plants at elevated COā. Phosphorus inflow was unaffected by COā concentrations. It is concluded that there is no direct permanent effect of elevated COā on mycorrhizal functioning, as internal mycorrhizal development and the mycorrhizal P uptake mechanism are unaffected. The importance of sequential harvests in experiments is discussed. The direction for future research is highlighted, especially in relation to C storage in the soil." |
