Vesicular Arbuscular

The degree of vesicular–arbuscular mycorrhizal root colonization of alpine fell-field plants was measured at six sites in the northern Rocky Mountains of Montana and Wyoming. Soils derived from calcareous or acidic crystalline parent materials were analyzed for chemical and physical properties and vesicular–arbuscular mycorrhizal fungal propagule density. Soils associated with calcareous parent materials had finer texture, higher pH, and higher levels of calcium, sodium, and silicon. Viable vesicular–arbuscular mycorrhizal propagule density was positively correlated with plant canopy cover. Typical vesicular–arbuscular mycorrhizal colonization occurred in 84% of the species examined. Vesicular–arbuscular mycorrhizal root colonization was significantly greater on soils derived from calcareous parent materials. Alkaline pH and high levels of calcium associated with calcareous soils may result in these soils being functionally more phosphorus deficient than are crystalline soils. Phosphorus deficiency may partially explain the higher levels of vesicular–arbuscular mycorrhizal colonization observed.

Context: Arbuscular-Mycorrhizal fungi colonization in roots of many plants promotes the increased nutrient uptake especially the phosphorus from phosphorus deficient soil.Objective: To compare the efficacy of different concentration of recommended dosages of super phosphate fertilizers with inoculation of AM fungi to evaluate growth, nutrients uptake on Niger plant (Guizotia abyssinica (L.f) Cass. var, RCR-18).Materials and Methods: The effect of two Arbuscular mycorrhizal fungi Scutellospora nigra and Glomus mosseae with 4 different dosage (25%, 50%, 75%, 100% ) of superphosphate (P2O5) was treated on growth yield and nutrient uptake in Niger plant (Guizotia abyssinica (L.f) Cass. var, RCR-18) was evaluated under greenhouse conditions. Pots were watered they were harvested once in 30 days intervals. For 90 days the following readings viz., plant height, root length, biomass, grains yield, percent root colonization, spore number macro-micro nutrients contents in shoots and roots were determined.Results: Scutellospora nigra with 50% RDSP/kg showed a significant increase in the plant growth biomass of shoot and root of Guizotia abyssinica (L.f) Cass. var, RCR-18. Percent root colonization, seed number and N, P, K and Zn, Mg uptake in shoot and root.Conclusion: Overall, our results clearly suggest that synergistic and additive mechanisms involved can enhances the plant growth, nutrient uptake and adaptation to unfavorable drought soil conditions.J. bio-sci. 22: 45-51, 2014
