Abstract

One of the most important symbioses in plants is Vesicular Arbuscular Mycorrhiza (VAM) fungus that has widespread distribution. Many plants that have special properties such as root morphologic properties have different symbiosis with VAM fungi. This symbiosis has different effects on each plant. The role of these fungi in absorption of non-mobile elements such as phosphate is more important. In a glasshouse experiment on two cultivar of clover, Trifolium alexanderinum and Trifolium subterraneum, the effects of soil applications of PHOSPHORUS fertilizer and inoculum of Glomus interraradice on the mycorrhizal colonization of roots, MYCORRHIZAL DEPENDENCY, crop yield and nutrient uptake were studied in autoclaved sterilized soil. Root length in the two cultivars was different. The applied P increased plants dry matter significantly but suppressed mycorrhizal infection. MYCORRHIZAL DEPENDENCY and percentage of ROOT COLONIZATION in T.alexanderium were more than those of T.SUBTERRANEUM. There was a negative correlation between MYCORRHIZAL DEPENDENCY and percentage ROOT COLONIZATION on one hand and applied PHOSPHORUS on the other. The highest ROOT COLONIZATION occurred in zero level of PHOSPHORUS and the lowest in 25 mgkg-1 PHOSPHORUS amounting to 55% and 8% respectively. With ROOT COLONIZATION and increasing PHOSPHORUS concentration, shoot and root dry weight were increased. However at higher PHOSPHORUS concentration (25 mgkg-1), the increase was not significant. In control (without mycorrhiza and 0 mgPkg-1 soil), dry root weight in T.SUBTERRANEUM was more than T.alexanderinum. The correlation between mycorrhizal colonization and PHOSPHORUS concentration on one hand and K content in plant tissues was negative.
