The effect of different land uses on arbuscular mycorrhizal fungi in the northwestern Black Sea Region
Özet
The object of the present research was to
establish correlations between the status of root colonization
of arbuscular mycorrhizal fungi (AMF) and different
types of land use. In order to achieve this aim,
rhizosphere soil samples from grassland crops were
taken during June and July of 2013 in order to use for
determining several soil characteristics. The 27 different
taxa and 60 soil samples were collected from the rhizosphere
level in the study areas. The existence of AMF
was confirmed in 100 % of these plants with different
rations of colonization (approximately 12–89 %).
Bromus racemosus L. (pasture) was the most dense
taxon with the percentage of AMF colonization of
88.9 %, and Trifolium pratense L. (forest) was the least
dense taxon with the percentage ofAMF colonization of
12.2 % (average 52.0 %). As a result of the statistical
analysis, a positive relationship was found between the
botanical composition of legumes and AMF colonization
(r=0.35; p =0.006). However, a negative relationship
was determined between botanical composition of
other plant families and AMF colonization (r= −0.39;
p =0.002). In addition, a positive relationship was defined
between soil pH (H2O) and the root colonization
of AMF (r = 0.35; p = 0.005). The pasture had the
highest mean value of AMF root colonization. However,
the pasture and gap in the forest were in the same
group, according to the results of the S-N-K test.
