Abstract |
: |
Used in this research nineteen soil sample farming for different crops were collected from different regions of the Western Region (Huda al-Sham - City - Taif), Saudi Arabia - and analyzed the samples analyzed chemically, and studied the presence germs fungus roots of the Interior (liposome tree) and the percentage of injury roots, and the ability of soil and bacteria derived from them to cause infection, and propagation Gratimha, and how some plants in response to vaccination and resistance to drought, and summarizes the results are as follows:
Divided the soil samples into several groups on the basis of chemical analysis, which included eight samples of soil is alkaline non-saline (3 samples from the area of guidance Sham 0.4 samples from the area of Taif, and one sample from the area of Medina) five samples of soil, mild salinity (one sample of Huda al-Sham area, two samples from the area of Taif 0.4 samples from the area of Medina) and sample the soil too salty (of Madinah). Different density of bacteria fungi roots of the Interior (liposome tree) is clearly distinct from the soil sample to the other, showed samples of soil, the rave-Sham highest numbers of bacteria (1104 to 3880 germ kg soil dry) and lower concentrations of salt, magnesium, sodium, potassium, bicarbonate, sulphate and phosphorus dissolved. The roots of plants, alfalfa, millet and Sudan grass farm in this region gave the highest infection rate (from 10.8 to 49.0%) compared to soil samples Taif and Medina.
It was noted that soil samples containing high numbers of fungal spores roots of the Interior, has encouraged the growth of plants, alfalfa, millet, and led to increased content of nitrogen, phosphorus and potassium from the control treatment. The results showed that the onion and corn from the most suitable families for the propagation of fungi liposome tree roots, and other families showed wide differences in this regard.
It was noted that plants sorghum Almikaurizih (infected with a mixture of fungal roots) are more drought resistant than other plants sorghum non-infected, and did not show plants alfalfa fertilized bacterial genus Scalirosests Sclerocystis and Jloms Glomus any activity in the utilization of protein (albumin bovine) as the sole source of nitrogen. |
