Comparative Analysis Of Biocenotic Complexes Of Wheat Nematodes And Wild Cereals

Abstract

The article provides a comparative analysis of biocenotic complexes of wheat nematodes and wild-growing cereal plants. Common methods in phytohelminthology were used to study the fauna of nematodes. As a result of studies in plants and root soil of wheat and wild grasses, 237 species of nematodes were registered. It is noted that on wheat and wild-growing cereals, the common dominant species are P. rigidus, A. avenae, A. parietinus, D. dipsaci. Also, the coefficient of similarity of faunistic complexes of wheat nematodes and wild-growing cereals was studied, and the found nematodes were distributed by ecological groups. It is argued that phytoparasites can transfer to cultivated plants from wild grasses, and also, the data confirm that wild grasses are reserves of parasitic nematodes, and can serve as a hotbed of preservation of nematode invasion for cultivated plants in Uzbekistan.
