Farklı Ağaç Türlerinin Geliştiği Yüzey Toprağının Mikrobiyal Popülasyonu

Özet

It is known that the number of the microbial population and their types around of the plant roots affected by the plant root secretions.
Leaves and the body parts of various plants (apple, lime, pine and walnut) will change the content of the upper layer of the soil that develops
the plants during the seasonal changes. Accordingly, that their microbial population in the upper soil of the trees will change have been
considered. For this purpose, four different trees that grow in the same region, were selected and their surface soil samples were taken from
different regions to be reached a depth of 5 -10 cm. These soil samples was mixed and used for the microbial analysis. In order to determine
the types of microorganisms and their number of the total micro-organisms, gram-negative bacteria and spore-forming bacteria (cfu/g) were
used by the serial dilution techniques. As a result, the highest number of the microorganisms and their types of microorganisms from the soil
of the apple tree, although the lowest number and their types of microorganisms was obtained from the soil of the pine tree. However, the
number of the gram-negative bacteria was the highest in the soil of linden tree, although the number of gram negative bacteria was in the soil
of pine tree. For spore - forming bacterium, the highest number from the walnut soil and the lowest number from the linden tree have been
obtained.
