The Effect of a Vesicular-Arbuscular Mycorrhiza on the Uptake of Soil Phosphorus by Strawberry (Fragria sp. Var. Cambridge Favourite)
Mycorrhizal and non-mycorrhizal strawberry plants, var. Cambridge Favourite, were grown in a soil low in available phosphorus as well as in the same soil dressed with KH2PO4. The soil was autoclaved and mycorrhizal plants were produced by inoculating young runner plants with sporocarps of an Endogone sp. capable of producing vesicular-arbuscular mycorrhiza in strawberry. Leachings of sporocarps were also added to the non-inoculated plants.
In the P-deficient soil, the mycorrhizal plants absorbed significantly more P and gave significantly higher dry matter production than the non-mycorrhizal plants. The latter showed acute phosphorus deficiency symptoms. There were no differences in the P uptake and the growth
of mycorrhizal and non-mycorrhizal plants in the phosphate-enriched soil.
