12 Jan Role of Mycorrhiza fungi in soil nutrient fixation
मिट्टी कें पोषक तत्व निर्धारण में माइकोराइजा कवक का योगदान Arbuscular mycorrhizal fungi (AMF) are obligate symbionts with higher plants. Mycorrhiza is the association between fungi and the roots of higher plants and microorganisms and higher plants. On a global scale, between 86% and 94% of plants are mycorrhizal. Mycorrhizal associations are mutualistic, neutral, or parasitic depending on the circumstances although mutualism is the dominant type.Associations between arbuscular mycorrhizal fungi (AMF) and plant roots are usually non-specific in terms of the fungus-plant pairings that are compatible. A positive effect of mycorrhizalinoculation on growth of plants in metal contaminated soils. Arbuscularmycorrhizas have the ability to alleviate many anthropogenic stresses, including effects of metals and polychlorinated aliphatic and phenolic pollutants. Remediation of soils contaminated with toxic pollutants using specific combinations of plants with mycorrhizal fungi deserves increased emphasis. Groups of mycorrhizas The two main types of mycorrhiza are ecto and endo mycorrhizas, differ in their structure and physiological relationships with host plant. Mycorrhiza fungi frequently stimulate plants to reduce root biomass and simultaneously expanding nutrient uptake capacity by extending far beyond root surfaces and proliferating in soil pores that are too small for root hairs to enter. Two mycorrhizal groups of fungal mycelium are: a) Endo mycorrhizas. The fungi live inside the cortical cells of the roots and also grow...
