Distribution and Association of Arbuscular Mycorrhizal Fungi in Different Cultivars of Wheat from Lalganj Pratapgarh District of Utter Pradesh, India

Abstract

Arbuscular mycorrhizal fungi are key components of soil micro-flora and obviously interact with other microorganisms in the rhizosphere which is the zone of influence of plant roots on microbial populations and other soil constituents. Keeping in view the importance of AM fungi, the present study was undertaken for assessing the AM fungal spore population dynamics in the rhizosphere soil and its colonization in rhizosphere soils in relation to soil physico-chemical factors. Present study represents an attempt to establish the qualitative and quantitative distribution of AM fungal species in rhizosphere soils of wheat. Thirteen different wheat cultivars collected from four different sites of Lalganj Pratapgarh (U.P.), India were examined for the AM infection. All the wheat cultivars were found to be infected with arbuscular mycorrhizae. However, their population in rhizosphere and root infection varied to a considerable extent from species to species. The maximum spore population and highest percentage of root colonization were found with the rhizosphere soil of cultivars Ankur Kedar.

Effect of Inoculation with Arbuscular Mycorrhizal Fungi on Selected Spring Wheat Lines

“…Arbuscular mycorrhizal fungi interact at the root-soil interface in a coordinated manner. Their hyphae absorb and translocate water and nutrients from the soil to the plant to increase its growth and development (Dwivedi, 2015;Priyadharsini & Muthukumar, 2015). Wheat is colonized by mycorrhizae, but colonization depends on AMF strains and soil conditions.…”

Modulating Effect of PGRs on Growth and Biochemical Traits in Rice (Oryza sativa L.) under Salt Stress

“…Rice is a critical source of food for more than 3 billion people annually. Rice is cultivated in 45 million hectare which is with a production of 120 million tones (Financial year 2020-2021) and productivity is 2550 kg/ha of our country" [1,2]. "Soil sodicity/salinity has become a severe threat to ensure global food security.…”

Amalgamation of arbuscular mycorrhizal fungi and phosphate solubilizing bacteria on growth and yield of Solanum lycopersicum L.

“…To reduce environmental contamination, particularly soil pollution, most experts propose using biofertilizers in combination with inorganic fertilizers in a sustainable manner to preserve soil health, productivity, disease resistance, and yield growth 28 (Lekberg and Koids 2005). The AM fungus differs with host ranges, according to Dwivedi 29 . Despite their widespread presence, they revealed that every taxonomic group of plants and the list of species not infected is likely devoid of microorganisms such as bacteria, fungi, and actinomycetes that may aid in crop yields by assisting in the solubilization of insoluble phosphorus and encouraging plant growth by providing hormone levels, vitamins, and other growth-promoting substances.…”
