Abstract:
In the present, rhizosphere soil samples were collected from ten species of weeds. That marginal soil was taken in different locations from Yezin Agricultural University Campus from June to December, 2018. The survey was the isolation of arbuscular mycorrhizal fungi (AMF) spores’ density and colonization of the ten species of roots was studied in Poaceae and Cyperaceae families. The experiments were carried out to isolate the AMF from ten species of root and rhizosphere soil from weeds. The eight species of weeds included in Poaceae families and two in Cyperaceae families. In this experiment, AMF and plant root hairs its play important roles in plant water uptake and absorb nutrients in soil. The relative of endomycorrhizae and a root hair were served in plant water relations and it’s were grown with or without inoculation of the AMF that were control drought conditions and water stress. All species of rhizosphere soils were observed the hyphae colonization percent and spores’ numbers. Arbuscular Mycorrhizal fungi colonization percent in roots was calculated by grid-line intersection method. The collected AMF spore number and populations used to count by spore descending method. In this experiment were showed the highest AMF percent that have been found in Echinochloa colona L. Link (92.62%). The lowest AMF colonization percent is Sporobolus diander (Retz.) P. Beauv (30.86). The highest number of AMF spores was found in Leptochloa chinensis (L.) Nees (25.71). The lowest number of AMF were Scirpus grossus L. (5.14). The largest size of AMF spores was observed in Echinochloa crus-galli (L.) Beauv. (443.0µm) and the smallest AMF spores’ size were found Saccharum spontaneum L. (49.08µm). Arbuscular Mycorrhizal fungi of vesicle and arbuscules were found in all ten species have been studies. This study result has highlighted the practical situations where AMF have a significant impact in restoring or maintaining soil health and fertility. Although, they probably represent the most significant plant microbe symbiosis of the complex microbial interactions that occur in the rhizosphere soil. In this experiment result, AMF and plant root hairs its play important roles in plant water uptake and absorb nutrients in soil, drought conditions and water stress.
