1- Introduction
Dust is one of the most important environmental challenges in recent years in the Middle East and Iran (Ghorchian et al., 2011). Studies show that in order to stabilize the soil to prevent the production of dust, mechanical methods can not always be used, but it is necessary to move towards biological methods. Therefore, in this study, the effect of mycorrhizal populations on some morpho-physiological
characteristics of plants and soil in order to control dust had been investigated. In addition, based on the
latest information sources and methods, as well as field visits and surveys, the necessary ground for this
research had been provided. In the present study, the symbiotic relationship between the plants of Haloxylon aphyllum, Tamarix aphylla, Nitraria schoberi and mycorrhizal fungi was first confirmed. Then, the effect of mycorrhiza on plant species under normal and stress-free conditions was investigated In addition, the effect of mycorrhizal fungi on plant species under water stress and salinity, the percentage of colonization and the use of wind tunnels to estimate the soil strength of the inoculated sample in three soil types and under three types of water stress had been investigated.
2-Methodology
The aim of this study was to improve plant development in reducing wind erosion. After sampling the soils of Rhizosphere, Haloxylon, Tamarix and Nitraria, seedlings in two levels of inoculation with and without mycorrhizal fungi, three levels without water stress, moderate water stress and severe water stress and three soil types: standard soil with ntutral Ec, Soil No. 1 with EC=0.5 and soil No. 2 with EC=6 were conducted as a greenhouse in a factorial design. By using wind tunnel tests, morphological characterization of plants and mycorrhiza colonization experiments on the roots of plants were studied. Mycorrhiza inoculation significantly increased shoot and root fresh weight, shoot and root dry weight, root area, root volume, shoot and root length, and decreased soil loss.
3-Results
The results of comparing the mean of Haloxylon (increase of 18 to 40, decrease of 10%), Tamarix (increase of 1to3% and increase of 1to3%) and Nitraria (increase of 1 to 3% and decrease of 1%) indicate that the effect of fungus Mycorrhiza has been based on the vegetative characteristics of the plant and the amount of soil wasted. The interaction of plant species and water stress in Haloxylon plant also had a reduction of about 35% in vegetative characteristics relative to normal water stress and 15% relative to moderate water stress. Regarding the interaction of plant species and water stress in Tamarix, there was a decrease of about 18 to 35% in vegetative characteristics compared to normal water stress and 9 to 20% relative to water stress. Due to the interaction of plant species and water stress, Nitraria plant also had a reduction of about 25% in vegetative characteristics relative to normal water stress and 38% relative to moderate water stress.
4-Discussion & Conclusion
In general, the results of the study on the percentage of colonization showed that with inoculation of
mycorrhizal fungi, the percentage of colonization of mycorrhizal fungi increased compared to the control
condition. According to the results of the study, the characteristics related to the biological performance of the plant such as fresh and dry weight, and root and plant height have been obtained. The increasing effect of mycorrhiza has been primarily attributed by various researchers to the increase in the area and expansion of plant roots due to the production of fungal fibers and the increase in the uptake of nitrogen, phosphorus, potassium, water and other nutrients, which in turn can lead to improvement in the photosynthesis, and growth and development of the aerial parts, and can, finally, increase the dry weight of the plant. Mycorrhizae increases plant and nutrient uptake due to effective increase in root uptake by hyphae. In addition, due to the effect of mycorrhizae on stomatal conductance, the photosynthetic rate of mycorrhizal plants is higher than that of plants not inoculated with mycorrhizae. In addition to increasing the plant growth and creating an extensive network of hyphae through nutrient uptake, arbuscular mycorrhizal fungi have an important role in improving soil structure and aggregate resistance by secreting a glycoprotein called glomalin and reducing soil wastage.
