[Comparison of the nematode fauna of winter wheat and wild grain in the foothill and lowland zones of Dagestan].

The nematode fauna of winter wheat and wild cereals in the foothill zone of Dagestan is richer than that in the lowland zone. From 117 species of nematodes recorded from the rhizosphere and organs of examined plants 105 species are reported from foothills and only 78 species from the lowland zone. In the foothill zone the average number of nematodes in 10g of root soil and organs of wheat amounts to 619 specimens, in wild cereals--to 347 specimens, in lowland zone--to 310 and 236 specimens respectively. This difference is caused by soil--climatic conditions.
