Abstract |
: |
There is no doubt, is the study of fungi, the distribution of grain to high temperature, as well as able to withstand the high temperatures in the western region of Saudi Arabia especially important, as expected, Joe the totals of these fungi in abundance in this part of the high temperature. This shows the importance of these fungi in abundance in this part of the high temperature. This shows the importance of these fungi when cultivating land in the area for the first time. Studies have shown that the research conducted in the presence of fungi, grain to high temperature, as well as fungi able to withstand the high heat in large numbers in soil taken from a site different from the cities of Mecca and Jeddah. She physiological studies conducted on some fungi isolated from the western region, the presence of a strong relationship between temperature and pH (pH), and salinity and the growth of fungi tested, where studies have shown the ability of these fungi to withstand degrees unusual of these factors. Was also in this research study the ability of fungi previously referred to the production of certain enzymes which the enzyme is known analyst of starch Balomelez, enzyme Alkazanez Alselloleezz.
The results showed that the presence and intensity of these fungi in general may differ depending on locations and type of existing vegetation, soil conditions and time of sampling in terms of content of moisture and organic matter, pH, and total dissolved salts in addition to the type of soil itself. Overall, the study showed richer lands of Mecca and Jeddah this fungus, while the results showed also contain soil samples taken from different sites of Taif and Medina, the small numbers of them. The fungi are the following:
Paecilomyces varitotii, Chaetomium
Olivaceum, Mucor pusillus, Acremonium alabamense, penicillium dupontii and Thermomyces lanuginosus.
Among the fungi Almt_khasl in this research, the most efficient fungi tested in the analysis of carbohydrates and protein and cellulosic likely presence in Almokhtlvat plant in the soil. Therefore not recommended to work on multiplication and distribution of this fungus is cultivated on the land or even work to create environmental conditions suitable for sustaining growth of the role they can play naturally in soil fertility. |
