| Abstract:
The effect of inoculation with the endomycorrhizal fungus Glomus macrocarpum on nutrient uptake and growth of three strawberry cultivars was evaluated under greenhouse conditions. Mycorrhizal and non-mycorrhizal plants were grown in a phosphorus-deficient soil dressed with insoluble rock phosphate (hydroxyapatite). Also, non-mycorrhizal plants were grown in the same soil fertilized with soluble phosphorus. The soil was not autoclaved. Shoot dry weight, concentration of phosphorus (P) in the leaves, total P uptake, leaf area, number of leaves, crowns and stolons were significantly higher in mycorrhizal plants than in non-mycorrhizal plants grown in the soil dressed with hydroxyapatite. Also, inoculation with the endomycorrhizal fungus increased shoot dry weight of the plants significantly compared to non-mycorrhizal plants which were fertilized with soluble phosphorus, but no significant difference was found between them regarding total P uptake. Mycorrhiza did not affect significantly the uptake of K, Ca and Mg. Concentration of micronutrients was lower in mycorrhizal plants than in non-mycorrhizal plants. The establishment of the mycorrhiza proved beneficial to the plants in the soil low in available phosphorus by means of increased P-uptake and growth. | |
